BAPI Extension

light111BAPI Extension


The BAPI FM interface supports standard fields but there can be cases  where the customer  adds some Z-fields to the db table / some other business function is activated in the system which in turn adds some fields to the DB tables. In either of the cases the standard BAPI interface won’t be able to update these  addon fields. SAP provides a way to update these addon fields in terms of BAPI Extension technique.

The bapi extension structure allows to pass the structure name ( name of the structure that contains addon fields) and values.  Once this is done, the BAPI takes care of updating the fields.

Let’s illustrate this- with Contract Account creation in SAP FICA.

Tx- CAA3

The highlighted section appears only when certain business function is activated in the system. Which means when certain business function is activated certain new fields added to the underlying DB table and the screen section appears.

The underlying DB table gets some fields with addition of INCLUDE structure.

Let;s check the BAPI used to create contract account. The highlighted structure in the TABLES section contains only the standard contract account fields.

567

Now the BAPI uses the EXTENSION to pass the addon fields to the interface.

89

The BAPI extension-in reference structure contains the addon fields.

The BAPI extension-in ddic reference structure- BAPIPAREX allows to pass the STRUCTURE name(BAPI_TE_FKKVKPI) and the values in the VALUEPART-1/2/3/4.
