GRPP 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 "Structure for Group Check of Items" 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_GRPP TYPE GRPP.
The GRPP table consists of various fields, each holding specific information or linking keys about Structure for Group Check of Items data available in SAP. These include POSNR (Sales Document Item), VFPKZ (Control indicator for availability check/delivery scheduling), STABLM (Line index for internal table processing), ETABLM (Line index for internal table processing)... 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. .
