How to Create a Decision Tree in BRF+

How to Create a Decision Tree in BRF+
1. Introduction

The Business Rule Framework Plus (BRF+) in SAP allows business users and developers to define and maintain business rules without extensive ABAP coding.
A Decision Tree is a graphical way of modeling conditional logic where each branch represents a decision point.

This manual explains how to create and test a Decision Tree in BRF+.

2. Launch BRF+ Workbench

Open SAP GUI.

Enter Transaction Code: BRF+ (or BRFPLUS).

The BRF+ Workbench opens in a browser-based window.

3. Create an Application

In the Workarea, select Create → Application.

Enter details such as:

Application Name: Z_DEMO_APP

Description: Demo application for decision tree

Package: $TMP (for local) or assign to a transport request

Save the application.

4. Create a Function

Inside the application, right-click and choose Create → Function.

Maintain the following:

Name: Z_DECISION_TREE_FUNC

Mode: Event Mode

Save the function.

5. Create a Decision Tree Object

Right-click on the function.

Select Create → Expression → Decision Tree.

Provide details:

Name: Z_DECISION_TREE

Description: Example for discount calculation

Save the object.

6. Define Input and Output Data Objects

Create input data objects for decision making, for example:

Order_Type (Data Type: CHAR)

Customer_Category (Data Type: CHAR)

Define an output object to hold the decision result, for example:

Discount_Value (Data Type: NUMC).

7. Model the Decision Tree Logic

Open the Decision Tree in the graphical editor.

Add branches and maintain conditions:

IF Order_Type = ‘ONLINE’ → Assign Discount_Value = 10.

IF Order_Type = ‘RETAIL’ → Assign Discount_Value = 5.

ELSE → Assign Discount_Value = 0.

Save and activate the decision tree.

8. Test the Decision Tree

Right-click on the decision tree and choose Test.

Enter test values, for example:

Order_Type = ONLINE

Customer_Category = GOLD

Execute and verify the result returned in Discount_Value.

9. Conclusion

We have successfully created a Decision Tree in BRF+.
This object can now be used in business functions to replace hard-coded logic, making it easier to maintain and update rules without changing ABAP code.

For complex business rules, you may also explore Decision Tables or Formulas in BRF+.
