Creating an Interactive Editable ALV in ABAP with Header-Item CRUD Functionality

In this blog post, we will explore a powerful ABAP implementation of an editable ALV using CL_GUI_ALV_GRID. This solution provides:

Interactive two-screen design (Header & Item)Double-click to header to itemField-level edit control via CELLTABFull CRUD operations (Create, Read, Update, Delete) for both header and item data

Scenario

We use two custom database tables:

Custom Table → Delivery Header Data (VBELN, ERNAM, ERDAT, VSTEL, VKORG)Custom Table → Delivery Item Data (VBELN, POSNR, MATNR, WERKS)

The goal is to allow users to edit only selected rows, protect primary key fields, and manage entries interactively.

1. Table Declarations

TABLES?

Custom transparent table containing delivery header data.Custom transparent table for delivery item data.These tables are used to fetch and store ALV grid data.

TABLES:ZDB_EDIT_ALV,ZDB_EDIT_ALV1.

2. Class Forward Declaration

CLASS DELIVERY DEFINITION DEFERRED.

Forward declares a class named DELIVERY used later to handle double-click events.This is necessary to register event handlers before the class is fully implemented.

3. Type Declarations

Defines a structure T_ZDB_EDIT_ALV to hold header data and editable styles.CELLTAB: Stores editable style info for ALV cell-level control.

Similarly, for item data:

4. Data Definitions

Internal tables and work areas for header (LT_LIKP, LS_LIKP) and item (LT_LIPS, LS_LIPS) records.Field catalog tables for header (LT_FCAT) and item (LT_FCAT1) ALVs.Layout configurations for header and item grids.Containers and ALV grid objects for screen 200 (header) and screen 100 (item).

5. Selection Screen Definition

Purpose: Creates a selection screen block with delivery number as the input filter.S_VBELN: Allows users to input multiple values or ranges for VBELN.TEXT-000: Refers to a text element (defined in SE32 or SE38) for the frame title.

6. Field Catalog for Item ALV

Uses VALUE #( ) constructor to populate the field catalog for the item-level ALV (LT_LIPS).COL_POS: Column order in the ALV.FIELDNAME: Field to display.COLTEXT: Header text.TABNAME: Reference table used for dynamic assignment (not required in OO ALV, but used for clarity here).

7. Layout Configuration for Item ALV

GRID_TITLE: Title of the ALV.SEL_MODE = ‘A’: Allows multiple row selection.NO_TOOLBAR = ‘X’: Hides the standard ALV toolbar.STYLEFNAME = ‘CELLTAB’: Tells ALV to use the CELLTAB column to control editable styles per cell.

8. Start-of-Selection

START-OF-SELECTION. CALL SCREEN 200.

Trigger point of the report after user input.It navigates to screen 200, which displays the header-level ALV.

9. Event Handler Class Definition

Defines a local class DELIVERY with method GET_DATA.The method is registered as an event handler for the double-click event of the ALV.

10. Class Implementation

GET_DATA is triggered when the user double-clicks on a row in header ALV.It reads the delivery number (VBELN) of the clicked row.Then fetches all matching item-level records from ZDB_EDIT_ALV1 into LT_LIPS.Opens Screen 100, which shows the item ALV.

11. Screen 100 (Item ALV) – OUTPUT Module

SET PF-STATUS ‘ZITEMS’: Sets the GUI status (button functions) for item screen.PERFORM CREATE_OBJECT_LIPS: Initializes the ALV Grid for item records.

12. Screen 100 – INPUT Module

Handles user actions on screen 100:BACK: Return to header ALV.CREATE: Add a new item row.EDIT: Enable selected row for editing.UPDATE: Update modified item data.DELETE: Remove selected rows.SAVE: Insert/update item data into DB.FORM CREATE_OBJECT_LIPS – Initializes ALV on Screen 100 (Item).MODULE STATUS_0200 OUTPUT – Prepares header ALV on Screen 200.MODULE USER_COMMAND_0200 INPUT – Handles toolbar actions for header ALV.Then we’ll go deeper into the CRUD FORMs (CREATE/EDIT/UPDATE/DELETE/SAVE) for both header and item ALVs.FORM CREATE_OBJECT_LIPS – Create ALV Grid for Items

Explanation:

CLEAR O_CONTAINER2: Reset reference before ALV creation (safety check).CREATE OBJECT O_CONTAINER2: Creates a custom container placed on the screen (SCREEN 100) using element CONTAINER2.CREATE OBJECT O_GRID2: Binds an ALV Grid (CL_GUI_ALV_GRID) to the container.SET_TABLE_FOR_FIRST_DISPLAY:IS_LAYOUT = LS_LAYO1: Applies previously configured layout for item ALV.IT_OUTTAB = LT_LIPS: Data source for the ALV.IT_FIELDCATALOG = LT_FCAT1: Column settings for the ALV.

13. MODULE STATUS_0200 OUTPUT – Setup Header Screen (Screen 200)

Explanation:

SET PF-STATUS ‘ZHEADER’: Sets GUI status for header toolbar (buttons: CREATE, EDIT, SAVE, etc.).The SELECT pulls header records from ZDB_EDIT_ALV based on delivery numbers entered on the selection screen.

ALV Grid Initialization:

Creates the custom container and grid for header-level display.

Field Catalog (LT_FCAT):

Each field is appended individually to LT_FCAT with attributes:

Layout for Header ALV:

Final ALV Setup:

Initializes header ALV with all settings and data.

Event Handler Registration:

Double-click on any row in header ALV triggers GET_DATA, which fetches corresponding items.

14. MODULE USER_COMMAND_0200 INPUT – Header Screen Toolbar Actions

Executes the relevant FORM based on user action on toolbar buttons:CREATE: Adds a new editable row.EDIT: Enables selected row for editing.SAVE: Inserts or updates data in DB.DELETE: Removes selected rows from ALV and DB.UPDATE: Commits modified data to DB.

15. FORM CHANGE_MODE – Enable Edit Mode for Selected Header Row

Purpose: Only the selected row becomes editable. All others stay read-only.LVC_T_ROID, LVC_S_STYL: Types for editable styles.CELLTAB is used for cell-level control.Gets the row(s) selected in the header ALV using LVC_ROWMARK.

Loop over each header entry to determine which row to enable.

Compares the current loop index with selected rows.If it’s selected, enable its editable fields.

If Selected Row → Enable ditable Fields

IF SY-SUBRC = 0. LS_STYLEROW-STYLE = CL_GUI_ALV_GRID=>MC_STYLE_DISABLED. LS_STYLEROW-FIELDNAME = ‘VBELN’. INSERT LS_STYLEROW INTO TABLE LT_STYLEROW.

VBELN is a primary key → disabled.Similarly disables ERNAM.

LS_STYLEROW-STYLE = CL_GUI_ALV_GRID=>MC_STYLE_ENABLED. LS_STYLEROW-FIELDNAME = ‘ERDAT’. INSERT LS_STYLEROW INTO TABLE LT_STYLEROW.

Enables only non-primary key fields for editing: ERDAT, VSTEL, VKORG.

Assign Cell Styles to Entry

CLEAR: LS_LIKP-CELLTAB. INSERT LINES OF LT_STYLEROW INTO TABLE LS_LIKP-CELLTAB. MODIFY LT_LIKP FROM LS_LIKP TRANSPORTING CELLTAB. CLEAR: LT_STYLEROW.

Applies the style to the current line.

Else – Row not selected → Make it fully non-editable

ELSE. LS_STYLEROW-STYLE = CL_GUI_ALV_GRID=>MC_STYLE_DISABLED. … INSERT LS_STYLEROW INTO TABLE LT_STYLEROW. … MODIFY LT_LIKP FROM LS_LIKP TRANSPORTING CELLTAB.

Toggle Grid Ready for Input

IF O_GRID1->IS_READY_FOR_INPUT( ) EQ 0. CALL METHOD O_GRID1->SET_READY_FOR_INPUT EXPORTING I_READY_FOR_INPUT = 1. ELSE. CALL METHOD O_GRID1->SET_READY_FOR_INPUT EXPORTING I_READY_FOR_INPUT = 0. ENDIF.

Activates input mode if not already.

O_GRID1->REFRESH_TABLE_DISPLAY( ).ENDFORM.

Refreshes the ALV to reflect the updated editable state.

16. FORM CREATE_HEADER_DATA – Add New Editable Header Row

FORM CREATE_HEADER_DATA . DATA: LS_NEW TYPE T_ZDB_EDIT_ALV, LT_STYLEROW TYPE STANDARD TABLE OF LVC_S_STYL WITH DEFAULT KEY, LS_STYLEROW TYPE LVC_S_STYL.

Prepares a new structure and editable field style list.

Set Editable Fields

LS_STYLEROW-FIELDNAME = ‘VBELN’. LS_STYLEROW-STYLE = CL_GUI_ALV_GRID=>MC_STYLE_ENABLED. APPEND LS_STYLEROW TO LT_STYLEROW.

All fields are enabled since it’s a new row. Even primary keys like VBELN, ERNAM.Repeats for: ERNAM, ERDAT, VSTEL, VKORG.

Assign Styles and Add New Entry

LS_NEW-CELLTAB = LT_STYLEROW. APPEND LS_NEW TO LT_LIKP.

Assigns the editable CELLTAB and appends the new row to the internal table.

CALL METHOD O_GRID1->SET_READY_FOR_INPUT EXPORTING I_READY_FOR_INPUT = 1. CALL METHOD O_GRID1->REFRESH_TABLE_DISPLAY.ENDFORM.

Turns on editable mode and refreshes ALV.

17. FORM DELETE_HEADER_DATA – Delete Selected Header Rows

FORM DELETE_HEADER_DATA . DATA: LT_ROWS TYPE LVC_T_ROW, LS_ROW TYPE LVC_S_ROW, LV_IDX TYPE SY-TABIX.

LT_ROWS: Holds the list of selected row indexes.LS_ROW: Work area for current row index.LV_IDX: Integer used to track which row index is being processed.

Get Selected Rows

CALL METHOD O_GRID1->GET_SELECTED_ROWS IMPORTING ET_INDEX_ROWS = LT_ROWS.

Fetches the selected row indexes in the header ALV grid.

Loop and Delete from DB & Internal Table

LOOP AT LT_ROWS INTO LS_ROW. LV_IDX = LS_ROW-INDEX. READ TABLE LT_LIKP INDEX LV_IDX INTO LS_LIKP. IF SY-SUBRC = 0. DELETE FROM ZDB_EDIT_ALV WHERE VBELN = LS_LIKP-VBELN. DELETE LT_LIKP INDEX LV_IDX. ENDIF. ENDLOOP.

For each selected row:Reads that entry from LT_LIKP.Deletes corresponding record from DB table ZDB_EDIT_ALV.Deletes it from internal table LT_LIKP.

Refresh ALV & Commit

CALL METHOD O_GRID1->REFRESH_TABLE_DISPLAY. COMMIT WORK. MESSAGE ‘Selected header(s) deleted’ TYPE ‘S’.ENDFORM.

Refreshes the ALV display.Saves DB changes using COMMIT WORK.Displays success message.

18. FORM SAVE_HEADER_DATA – Insert or Update Header Records

FORM SAVE_HEADER_DATA .

Flat Structure Definition

TYPES: BEGIN OF TY_ZDB_EDIT_ALV_FLAT, VBELN TYPE ZDB_EDIT_ALV-VBELN, ERNAM TYPE ZDB_EDIT_ALV-ERNAM, ERDAT TYPE ZDB_EDIT_ALV-ERDAT, VSTEL TYPE ZDB_EDIT_ALV-VSTEL, VKORG TYPE ZDB_EDIT_ALV-VKORG, END OF TY_ZDB_EDIT_ALV_FLAT. DATA: LS_DB_ALV_FLAT TYPE TY_ZDB_EDIT_ALV_FLAT.

This structure excludes CELLTAB and is used to write data into the DB.

Ensure User Changes Are Captured

CALL METHOD O_GRID1->CHECK_CHANGED_DATA.

Updates the internal table (LT_LIKP) with user input from the ALV grid.

Loop Through Header Table and Save to DB

LOOP AT LT_LIKP INTO LS_LIKP. LS_DB_ALV_FLAT-VBELN = LS_LIKP-VBELN. LS_DB_ALV_FLAT-ERNAM = LS_LIKP-ERNAM. LS_DB_ALV_FLAT-ERDAT = LS_LIKP-ERDAT. LS_DB_ALV_FLAT-VSTEL = LS_LIKP-VSTEL. LS_DB_ALV_FLAT-VKORG = LS_LIKP-VKORG.

Copies the values to a flat version to avoid CELLTAB structure issues.

Insert or Update Logic

SELECT SINGLE VBELN INTO @DATA(LV_VBELN) FROM ZDB_EDIT_ALV WHERE VBELN = @LS_DB_ALV_FLAT-VBELN AND ERNAM = @LS_DB_ALV_FLAT-ERNAM. IF SY-SUBRC = 0. UPDATE ZDB_EDIT_ALV SET ERDAT = @LS_DB_ALV_FLAT-ERDAT, VSTEL = @LS_DB_ALV_FLAT-VSTEL, VKORG = @LS_DB_ALV_FLAT-VKORG WHERE VBELN = @LS_DB_ALV_FLAT-VBELN AND ERNAM = @LS_DB_ALV_FLAT-ERNAM. ELSE. INSERT ZDB_EDIT_ALV FROM LS_DB_ALV_FLAT. ENDIF. ENDLOOP.

If record exists (same VBELN & ERNAM) → UPDATE.Else → INSERT as new record.

COMMIT WORK. MESSAGE ‘Header data saved successfully’ TYPE ‘S’.ENDFORM.

Final commit and success message.

19. FORM UPDATE_HEADER_DATA – Update Header Records

FORM UPDATE_HEADER_DATA . CALL METHOD O_GRID1->CHECK_CHANGED_DATA.

Reads current ALV data into LT_LIKP.

Loop and Upsert to DB

abapCopyEdit LOOP AT LT_LIKP INTO LS_LIKP. LS_DB_ALV_FLAT-VBELN = LS_LIKP-VBELN. LS_DB_ALV_FLAT-ERNAM = LS_LIKP-ERNAM. LS_DB_ALV_FLAT-ERDAT = LS_LIKP-ERDAT. LS_DB_ALV_FLAT-VSTEL = LS_LIKP-VSTEL. LS_DB_ALV_FLAT-VKORG = LS_LIKP-VKORG.

Maps data into a flat structure.

abapCopyEdit SELECT SINGLE VBELN INTO @DATA(LV_VBELN) FROM ZDB_EDIT_ALV WHERE VBELN = @LS_DB_ALV_FLAT-VBELN AND ERNAM = @LS_DB_ALV_FLAT-ERNAM. IF SY-SUBRC = 0. UPDATE ZDB_EDIT_ALV SET ERDAT = @LS_DB_ALV_FLAT-ERDAT, VSTEL = @LS_DB_ALV_FLAT-VSTEL, VKORG = @LS_DB_ALV_FLAT-VKORG WHERE VBELN = @LS_DB_ALV_FLAT-VBELN AND ERNAM = @LS_DB_ALV_FLAT-ERNAM. ELSE. INSERT ZDB_EDIT_ALV FROM LS_DB_ALV_FLAT. ENDIF. ENDLOOP.

Same insert/update logic as SAVE

COMMIT WORK. MESSAGE ‘Header data Updated successfully’ TYPE ‘S’.ENDFORM.

That completes the full documentation of header-level editable ALV with CRUD.

Next, I’ll begin the item-level ALV explanation starting with:

FORM CHANGE_ITEMS_MODEFORM CREATE_ITEMS_DATAFORM DELETE_ITEMS_DATAFORM SAVE_ITEMS_DATAFORM UPDATE_ITEMS_DATA

20. FORM CHANGE_ITEMS_MODE – Make Only Selected Item Row Editable

FORM CHANGE_ITEMS_MODE . DATA: LT_INDEX_ROWS TYPE LVC_T_ROW, LT_ROW_NO TYPE LVC_T_ROID, LS_ROW_NO TYPE LVC_S_ROID, LS_STYLEROW TYPE LVC_S_STYL, LT_STYLEROW TYPE TABLE OF LVC_S_STYL.

Similar to header edit logic.Used to control which single row in the item ALV becomes editable.

CALL METHOD O_GRID2->GET_SELECTED_ROWS IMPORTING ET_ROW_NO = LT_ROW_NO.

Retrieves the selected item rows using LVC_ROWMARK.

Loop Over All Rows and Toggle Editable Mode

IF NOT LT_ROW_NO IS INITIAL. LOOP AT LT_LIPS INTO LS_LIPS. READ TABLE LT_ROW_NO INTO LS_ROW_NO WITH KEY ROW_ID = SY-TABIX.

For each item row in LT_LIPS, check if it’s selected.

If Selected: Enable Editable Fields

IF SY-SUBRC = 0. LS_STYLEROW-STYLE = CL_GUI_ALV_GRID=>MC_STYLE_DISABLED. LS_STYLEROW-FIELDNAME = ‘VBELN’. INSERT LS_STYLEROW INTO TABLE LT_STYLEROW. LS_STYLEROW-FIELDNAME = ‘POSNR’. INSERT LS_STYLEROW INTO TABLE LT_STYLEROW. LS_STYLEROW-STYLE = CL_GUI_ALV_GRID=>MC_STYLE_ENABLED. LS_STYLEROW-FIELDNAME = ‘MATNR’. INSERT LS_STYLEROW INTO TABLE LT_STYLEROW. LS_STYLEROW-FIELDNAME = ‘WERKS’. INSERT LS_STYLEROW INTO TABLE LT_STYLEROW.

VBELN and POSNR are primary keys → disabled.Only MATNR, WERKS are editable.

CLEAR: LS_LIPS-CELLTAB. INSERT LINES OF LT_STYLEROW INTO TABLE LS_LIPS-CELLTAB. MODIFY LT_LIPS FROM LS_LIPS TRANSPORTING CELLTAB. CLEAR: LT_STYLEROW.

Applies the cell-style configuration to the current row.

Else: Disable All Fields for Non-Selected Rows

ELSE. LOOP AT FIELDS: ‘VBELN’, ‘POSNR’, ‘MATNR’, ‘WERKS’. LS_STYLEROW-FIELDNAME = FIELD. LS_STYLEROW-STYLE = CL_GUI_ALV_GRID=>MC_STYLE_DISABLED. INSERT LS_STYLEROW INTO TABLE LT_STYLEROW. ENDLOOP. CLEAR: LS_LIPS-CELLTAB. INSERT LINES OF LT_STYLEROW INTO TABLE LS_LIPS-CELLTAB. MODIFY LT_LIPS FROM LS_LIPS TRANSPORTING CELLTAB. CLEAR: LT_STYLEROW.

Toggle Edit Mode and Refresh ALV

IF O_GRID2->IS_READY_FOR_INPUT( ) EQ 0. CALL METHOD O_GRID2->SET_READY_FOR_INPUT EXPORTING I_READY_FOR_INPUT = 1. ELSE. CALL METHOD O_GRID2->SET_READY_FOR_INPUT EXPORTING I_READY_FOR_INPUT = 0. ENDIF. O_GRID2->REFRESH_TABLE_DISPLAY( ).ENDFORM.

21. FORM CREATE_ITEMS_DATA – Add New Editable Row in Item ALV

Enable All Fields (for Create)

LS_STYLEROW-FIELDNAME = ‘VBELN’. LS_STYLEROW-STYLE = CL_GUI_ALV_GRID=>MC_STYLE_ENABLED. APPEND LS_STYLEROW TO LT_STYLEROW. … (Repeat for POSNR, MATNR, WERKS)

All fields are enabled so user can create new record from scratch.

LS_NEW-CELLTAB = LT_STYLEROW. APPEND LS_NEW TO LT_LIPS. CALL METHOD O_GRID2->SET_READY_FOR_INPUT EXPORTING I_READY_FOR_INPUT = 1. CALL METHOD O_GRID2->REFRESH_TABLE_DISPLAY.ENDFORM.

Appends the new row to ALV and switches to input mode.

22. FORM DELETE_ITEMS_DATA – Delete Selected Item Rows

FORM DELETE_ITEMS_DATA . DATA: LT_ROWS TYPE LVC_T_ROW, LS_ROW TYPE LVC_S_ROW, LV_IDX TYPE SY-TABIX. CALL METHOD O_GRID2->GET_SELECTED_ROWS IMPORTING ET_INDEX_ROWS = LT_ROWS.

Gets the selected item row indexes from ALV.

LOOP AT LT_ROWS INTO LS_ROW. LV_IDX = LS_ROW-INDEX. READ TABLE LT_LIPS INDEX LV_IDX INTO LS_LIPS. IF SY-SUBRC = 0. DELETE FROM ZDB_EDIT_ALV1 WHERE VBELN = LS_LIPS-VBELN. DELETE LT_LIPS INDEX LV_IDX. ENDIF. ENDLOOP. CALL METHOD O_GRID2->REFRESH_TABLE_DISPLAY. COMMIT WORK. MESSAGE ‘Selected header(s) deleted’ TYPE ‘S’.ENDFORM.

Deletes item records from both DB and internal table.

23. FORM SAVE_ITEMS_DATA – Insert or Update Item Rows

FORM SAVE_ITEMS_DATA . DATA: LS_DB_ALV1 TYPE TY_ZDB_EDIT_ALV1_FLAT, LS_DB_FULL TYPE ZDB_EDIT_ALV1, LV_VBELN TYPE ZDB_EDIT_ALV1-VBELN. CALL METHOD O_GRID2->CHECK_CHANGED_DATA.

Converts ALV changes to internal table.Flat structure is used to exclude CELLTAB.

Loop Through Item Table

LOOP AT LT_LIPS INTO LS_LIPS. LS_DB_ALV1-VBELN = LS_LIPS-VBELN. LS_DB_ALV1-POSNR = LS_LIPS-POSNR. LS_DB_ALV1-MATNR = LS_LIPS-MATNR. LS_DB_ALV1-WERKS = LS_LIPS-WERKS.

Transfer values from ALV row to flat structure.

DB Insert/Update Logic

SELECT SINGLE VBELN INTO @LV_VBELN FROM ZDB_EDIT_ALV1 WHERE VBELN = @LS_DB_ALV1-VBELN AND POSNR = @LS_DB_ALV1-POSNR. IF SY-SUBRC = 0.

24. FORM UPDATE_ITEMS_DATA – Update Existing Item Records

FORM UPDATE_ITEMS_DATA . DATA: LS_DB_ALV1 TYPE TY_ZDB_EDIT_ALV1_FLAT, LS_DB_FULL TYPE ZDB_EDIT_ALV1, LV_VBELN TYPE ZDB_EDIT_ALV1-VBELN. CALL METHOD O_GRID2->CHECK_CHANGED_DATA.

Same structure and update logic as SAVE.

LOOP AT LT_LIPS INTO LS_LIPS. LS_DB_ALV1-VBELN = LS_LIPS-VBELN. LS_DB_ALV1-POSNR = LS_LIPS-POSNR. LS_DB_ALV1-MATNR = LS_LIPS-MATNR. LS_DB_ALV1-WERKS = LS_LIPS-WERKS. SELECT SINGLE VBELN INTO @DATA(S_VBELN) FROM ZDB_EDIT_ALV1 WHERE VBELN = @LS_DB_ALV1-VBELN AND POSNR = @LS_DB_ALV1-POSNR. IF SY-SUBRC = 0.

MOVE-CORRESPONDING LS_DB_ALV1 TO LS_DB_FULL. INSERT ZDB_EDIT_ALV1 FROM LS_DB_FULL. ENDIF. ENDLOOP. COMMIT WORK. MESSAGE ‘Item data Updated successfully’ TYPE ‘S’.ENDFORM.Output:

Header Output

When I was click on edit button

When I was click on create button

When I was create a new row delete button

When I was click on create buttom multiple append rows also created in both header and item also

If I was save on empty row Its shows as

If was double click on empty on no items was displayed and Header empty row it will not created on items details

Same actions performs in CURD operations in item level also:

In this blog post, we will explore a powerful ABAP implementation of an editable ALV using CL_GUI_ALV_GRID. This solution provides:Interactive two-screen design (Header & Item)Double-click to header to itemField-level edit control via CELLTABFull CRUD operations (Create, Read, Update, Delete) for both header and item data ScenarioWe use two custom database tables:Custom Table → Delivery Header Data (VBELN, ERNAM, ERDAT, VSTEL, VKORG)Custom Table → Delivery Item Data (VBELN, POSNR, MATNR, WERKS)The goal is to allow users to edit only selected rows, protect primary key fields, and manage entries interactively.1. Table DeclarationsTABLES? Custom transparent table containing delivery header data.Custom transparent table for delivery item data.These tables are used to fetch and store ALV grid data.TABLES:ZDB_EDIT_ALV,ZDB_EDIT_ALV1. 2. Class Forward DeclarationCLASS DELIVERY DEFINITION DEFERRED.Forward declares a class named DELIVERY used later to handle double-click events.This is necessary to register event handlers before the class is fully implemented. 3. Type DeclarationsDefines a structure T_ZDB_EDIT_ALV to hold header data and editable styles.CELLTAB: Stores editable style info for ALV cell-level control.Similarly, for item data: 4. Data DefinitionsInternal tables and work areas for header (LT_LIKP, LS_LIKP) and item (LT_LIPS, LS_LIPS) records.Field catalog tables for header (LT_FCAT) and item (LT_FCAT1) ALVs.Layout configurations for header and item grids.Containers and ALV grid objects for screen 200 (header) and screen 100 (item).5. Selection Screen Definition Purpose: Creates a selection screen block with delivery number as the input filter.S_VBELN: Allows users to input multiple values or ranges for VBELN.TEXT-000: Refers to a text element (defined in SE32 or SE38) for the frame title. 6. Field Catalog for Item ALVUses VALUE #( ) constructor to populate the field catalog for the item-level ALV (LT_LIPS).COL_POS: Column order in the ALV.FIELDNAME: Field to display.COLTEXT: Header text.TABNAME: Reference table used for dynamic assignment (not required in OO ALV, but used for clarity here). 7. Layout Configuration for Item ALVGRID_TITLE: Title of the ALV.SEL_MODE = ‘A’: Allows multiple row selection.NO_TOOLBAR = ‘X’: Hides the standard ALV toolbar.STYLEFNAME = ‘CELLTAB’: Tells ALV to use the CELLTAB column to control editable styles per cell. 8. Start-of-SelectionSTART-OF-SELECTION. CALL SCREEN 200.Trigger point of the report after user input.It navigates to screen 200, which displays the header-level ALV.9. Event Handler Class DefinitionDefines a local class DELIVERY with method GET_DATA.The method is registered as an event handler for the double-click event of the ALV. 10. Class Implementation GET_DATA is triggered when the user double-clicks on a row in header ALV.It reads the delivery number (VBELN) of the clicked row.Then fetches all matching item-level records from ZDB_EDIT_ALV1 into LT_LIPS.Opens Screen 100, which shows the item ALV. 11. Screen 100 (Item ALV) – OUTPUT Module SET PF-STATUS ‘ZITEMS’: Sets the GUI status (button functions) for item screen.PERFORM CREATE_OBJECT_LIPS: Initializes the ALV Grid for item records. 12. Screen 100 – INPUT Module Handles user actions on screen 100:BACK: Return to header ALV.CREATE: Add a new item row.EDIT: Enable selected row for editing.UPDATE: Update modified item data.DELETE: Remove selected rows.SAVE: Insert/update item data into DB.FORM CREATE_OBJECT_LIPS – Initializes ALV on Screen 100 (Item).MODULE STATUS_0200 OUTPUT – Prepares header ALV on Screen 200.MODULE USER_COMMAND_0200 INPUT – Handles toolbar actions for header ALV.Then we’ll go deeper into the CRUD FORMs (CREATE/EDIT/UPDATE/DELETE/SAVE) for both header and item ALVs.FORM CREATE_OBJECT_LIPS – Create ALV Grid for ItemsExplanation:CLEAR O_CONTAINER2: Reset reference before ALV creation (safety check).CREATE OBJECT O_CONTAINER2: Creates a custom container placed on the screen (SCREEN 100) using element CONTAINER2.CREATE OBJECT O_GRID2: Binds an ALV Grid (CL_GUI_ALV_GRID) to the container.SET_TABLE_FOR_FIRST_DISPLAY:IS_LAYOUT = LS_LAYO1: Applies previously configured layout for item ALV.IT_OUTTAB = LT_LIPS: Data source for the ALV.IT_FIELDCATALOG = LT_FCAT1: Column settings for the ALV. 13. MODULE STATUS_0200 OUTPUT – Setup Header Screen (Screen 200)Explanation:SET PF-STATUS ‘ZHEADER’: Sets GUI status for header toolbar (buttons: CREATE, EDIT, SAVE, etc.).The SELECT pulls header records from ZDB_EDIT_ALV based on delivery numbers entered on the selection screen.ALV Grid Initialization:Creates the custom container and grid for header-level display.Field Catalog (LT_FCAT):Each field is appended individually to LT_FCAT with attributes: Layout for Header ALV: Final ALV Setup: Initializes header ALV with all settings and data.Event Handler Registration: Double-click on any row in header ALV triggers GET_DATA, which fetches corresponding items. 14. MODULE USER_COMMAND_0200 INPUT – Header Screen Toolbar Actions Executes the relevant FORM based on user action on toolbar buttons:CREATE: Adds a new editable row.EDIT: Enables selected row for editing.SAVE: Inserts or updates data in DB.DELETE: Removes selected rows from ALV and DB.UPDATE: Commits modified data to DB.15. FORM CHANGE_MODE – Enable Edit Mode for Selected Header RowPurpose: Only the selected row becomes editable.
