BPCG_ID 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 "As BPCG with ID for 'Delete', 'Insert'" 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_BPCG_ID TYPE BPCG_ID.
The BPCG_ID table consists of various fields, each holding specific information or linking keys about As BPCG with ID for 'Delete', 'Insert' data available in SAP. These include MANDT (Client), OBJNR (Object number), POSIT (Internal commitment item (8 chars)), TRGKZ (Object indicator)... 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. .
