BAPI_FM_SPLIT is a standard SAP Structure so does not store data like a database table does. It can be used to define the fields of other actual tables or to process "ExtensionIn structure for RBAA Split" Information within sap ABAP programs. This is done by declaring abap internal tables, work areas or database tables based on this Structure. These can then be used to store and process the required data appropriately. i.e. DATA: wa_BAPI_FM_SPLIT TYPE BAPI_FM_SPLIT.
The BAPI_FM_SPLIT table consists of various fields, each holding specific information or linking keys about ExtensionIn structure for RBAA Split data available in SAP. These include FM_SPLIT_SEQUENCE_NBR (Sequence number for Rule-Based Acct Asst Distributions), FM_SPLIT_BATCH (Batch to group results from an PSM assignment distribution), FM_SPLIT_AUTH_GROUP (Authorization group for PSM account assignment distribution)...
