RMSAS_PP_ERROR 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-ATL: Error Information" 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_RMSAS_PP_ERROR TYPE RMSAS_PP_ERROR.
The RMSAS_PP_ERROR table consists of various fields, each holding specific information or linking keys about RMS-ATL: Error Information data available in SAP. These include MSGTY (Message Type), MSGNO (Message Number), MSGV1 (Message Variable), MSGV2 (Message Variable)...
