GRFN_S_TASKPLAN_GENERAL_API 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 "Task plan (Used by GRFN_S_TASKPLAN_GRP_GEN_API only)" 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_TASKPLAN_GENERAL_API TYPE GRFN_S_TASKPLAN_GENERAL_API.
The GRFN_S_TASKPLAN_GENERAL_API table consists of various fields, each holding specific information or linking keys about Task plan (Used by GRFN_S_TASKPLAN_GRP_GEN_API only) data available in SAP.
