BBPIMLINK 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 "EBR: Goods Receipt IDOC Link" 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_BBPIMLINK TYPE BBPIMLINK.
The BBPIMLINK table consists of various fields, each holding specific information or linking keys about EBR: Goods Receipt IDOC Link data available in SAP. These include PO_ITEM (Item Number of Purchasing Document), OBJKEY (Object key), LOGSYS (Logical system), GUID (GUID of a CRM Order Object)... 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. .
