RSPLAPI_S_SEQ_HEADER 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 "Header Information of Planning Sequence" 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_RSPLAPI_S_SEQ_HEADER TYPE RSPLAPI_S_SEQ_HEADER.
The RSPLAPI_S_SEQ_HEADER table consists of various fields, each holding specific information or linking keys about Header Information of Planning Sequence data available in SAP. These include OBJVERS (Object version), TXTLG (Long description), TSTPNM (Last changed by), DATUM (System Date)...
