In the ABAP program flow, use mapping variables and parameters in the following ABAP program objects: filter conditions, join conditions, and ABAP code blocks. The type of mapping variables and parameters you use depends on how the SAP server processes the ABAP program object.

Use both user-defined and built-in mapping variables and parameters in dynamic filter conditions. The Designer stores dynamic filter conditions in the repository. When you run a workflow, the PowerCenter Integration Service evaluates the variable or parameter and passes the filter from the repository to the SAP system. Then the ABAP program calls a function to process the dynamic filter.

You cannot use built-in mapping variables in static filter conditions because the SAP server processes the static filter directly from the ABAP program. The PowerCenter Integration Service does not pass values from the repository to the SAP system. Similarly, you cannot use built-in mapping variables in join conditions and ABAP code blocks.

The following table shows the types of mapping variables you can use with each object in the ABAP program flow:

Use mapping parameters in all ABAP program objects.
