RSPLSPC_S_SUBPROCESS 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 "Parellel Execution: Parameters for Subprocess" 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_RSPLSPC_S_SUBPROCESS TYPE RSPLSPC_S_SUBPROCESS.
The RSPLSPC_S_SUBPROCESS table consists of various fields, each holding specific information or linking keys about Parellel Execution: Parameters for Subprocess data available in SAP. These include SEQNM (Name (ID) of Planning Sequence), VARVARIANT (Technical Name of Variant), STEPID (Step in Planning Sequence), FUNCTION (Name of Planning Function)... 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. .
