What is Covert Key ? – When we are using standard BDEF for our development, some time we can see standard BDEF using “Late Numbering” for creating preliminary key %pid.
For example, for PO Creation we use BDEF I_PurchaseOrderTP_2 , for Purchase Contract BDEF is I_PurchaseContractTP and for Service Entry Sheet BDEF r_serviceentrysheettp.
During CREATE operation using EML, in MAPPED parameter will only return a preliminary key %pid. Then to retrieve the final key in our application from this preliminary key we must use the CONVERT KEY key word.
This conversion will call in SAVE Sequence in SAVE_MODIFIED method. And for this we need to use either Unmanaged Save or Additional Save.
Note:- If we want to save this convert key into the persistence of our own RAP business object, then we must use the unmanaged save approach.
For Example, here I am using BDEF r_serviceentrysheettp.
Scenario 1– When we are call EML inside our BDEF.
I have created an app where Service Entry Sheet will create when user click on Action Button.
I have used managed with unmanaged save implementation.
In Behavior Implementation class (Global Section) I have defined a variable that will hold the response of my API call.
In Action “createses” method
Here in variable mapped_serviceentry_sheet we will hold the response of our API call i.e. MAPPED data.
In debugging we can see the %PID value.
Here we can see EML is returning only preliminary key, that we need to convert in SAVE_MODIFIED method.
In debugging –
Scenario 2 – Call EML outside BDEF or normal class.
In Debugging –
Thanks
