GRFN_S_PLANUSAGE 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 "Planner usage configuration" 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_GRFN_S_PLANUSAGE TYPE GRFN_S_PLANUSAGE.
The GRFN_S_PLANUSAGE table consists of various fields, each holding specific information or linking keys about Planner usage configuration data available in SAP. These include IMPL_CLASS (ABAP class name for selection procedure implementation), ENTITY (Entity ID), HIDE_OU_SIGNOFF (Data element for domain BOOLE: TRUE (='X') and FALSE (=' ')), SELECT_OU (Data element for domain BOOLE: TRUE (='X') and FALSE (=' '))... 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. .
