Application Source Qualifier for SAP ECC Sources Overview
Application Source Qualifier for SAP ECC Sources Overview
When you add an SAP ECC source definition to a mapping, connect it to an Application Source Qualifier transformation. The Application Source Qualifier represents the record set queried from the SAP ECC source when you run a session.
When you complete the mapping, generate and install the ABAP program that the SAP application server uses to extract source data.
The Designer generates an ABAP program based on the properties in the source definition and the Application Source Qualifier. The Designer can generate open SQL, exec SQL, or ABAP join syntax. You can also set tracing level for session processing.
In the Application Source Qualifier, you can customize the ABAP program in the ABAP Program Flow dialog box. The ABAP Program Flow dialog box shows the order that the ABAP program processes objects. You can configure properties such as filter condition and join condition in the ABAP Program Flow dialog box.
In the ABAP Program Flow dialog box, use static or dynamic filters to specify how the ABAP program selects rows. You can also add more functionality to the ABAP program by adding ABAP code blocks. You can create variables and import SAP functions to use in the ABAP code or filter condition.
If you join multiple sources with one Application Source Qualifier, you can specify how the ABAP program joins the source tables. You can also specify the order that the ABAP program selects the source tables.
