BAPI_0038_DATA 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 "Funded Program data structure" 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_0038_DATA TYPE BAPI_0038_DATA.
The BAPI_0038_DATA table consists of various fields, each holding specific information or linking keys about Funded Program data structure data available in SAP. These include VALID_FROM (FM: Valid from date), VALID_TO (FM: Valid to date), DATE_EXP (Expiration Date), FM_AUTHGR_MEASURE (FM: Funded Program Authorization Group)... See below for full list along with technical details, documentation, text table, check tables, foreign key relationships, conversion routines, relevant tcodes and example ABAP select code etc. .
