SAP BAPI

This section provides information on how to connect to SAP BAPI. Before creating a Function, ensure you have already created the corresponding System within a System Line.

Connect to SAP BAPI​

In order to connect to SAP BAPI, create a new Function in the menu 'Virtual Datasets' and directly assign it to a Category.
Next, select the relevant Technical Handler 'BAPI'.
All other configuration (e. g. a descriptive Short Name and Description) has to be made as usual.

For the Technical Parameters, please specify the following options. The options in BOLD are REQUIRED:

  • FUNCTION: BAPI function name
  • RESULT_PATH: Result locator for BAPI result.

The valid options for the RESULT_PATH are defined by the exports of the BAPI function that is called. The BAPI function BAPI_USER_GET_DETAIL for instance returns these parameters and tables:

All exported parameter names are valid RESULT_PATHs. VDP functions always return tables, hence BAPI export parameters will be handled accordingly:

  • Atomic values (e. g. IDENTITY): returned as a table with one column and one row
  • Structure: returned as a table with one row and columns for all included fields (fields in structures that are structures or tables are shown as JSON strings)
  • Table: returned as table identical to the BAPI parameter table (cells in tables that are structures or tables are shown as JSON strings)

To have VDP return only one field of a structure, you can specify the export parameter and the field name. The result path of the user's last name in this example is ADDRESS/LASTNAME.
