MRTRSS_API_PSTREL 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 "RMS-MRTRS: GR Stage-MR Operation (Appl Layer)" 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_MRTRSS_API_PSTREL TYPE MRTRSS_API_PSTREL.
The MRTRSS_API_PSTREL table consists of various fields, each holding specific information or linking keys about RMS-MRTRS: GR Stage-MR Operation (Appl Layer) data available in SAP.
