BBP_POLINKS 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 "IDOC Links to Follow-up Documents of Purchase Order" 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_BBP_POLINKS TYPE BBP_POLINKS.
The BBP_POLINKS table consists of various fields, each holding specific information or linking keys about IDOC Links to Follow-up Documents of Purchase Order data available in SAP. These include PO_ITEM (Item Number of Purchasing Document), CLIENT (Client), WI_ID (Work item ID), ELEMENT (Element)... 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. .
