The ABAP Program Flow dialog box in the Application Source Qualifier shows the order of objects in the ABAP program and how you can customize the program.
The ABAP program selects tables and objects according to the order in the program flow. Select a table in the program flow to configure the filter condition, join type, and join condition for the selected table. You can complete the following tasks in the ABAP Program Flow dialog box:
Change the order of the program flow.
Use the up and down arrows to arrange the order of objects in the program flow.
Insert SAP functions.
You can insert SAP functions in the program flow after you have imported them in the Source Analyzer.
Create and insert ABAP code blocks in the program flow.
You can add new functionality to the program flow by inserting more blocks of ABAP code. Use ABAP program variables in the code block.
Create ABAP program variables.
You can create ABAP program variables to represent values in the ABAP program. The ABAP program variables can also represent SAP system variables.
Filter data using dynamic or static filters.
Use dynamic or static filters to reduce the rows that the ABAP program selects. Use ABAP program variables with static filters.
Override the default join type and join condition.
If you use multiple sources in the mapping, you can join them with one Application Source Qualifier. You can choose how the ABAP program joins the sources.
In the Mapping Designer, you can also configure the source definition to override the default query with a Select Single or Select Distinct statement.
