RMXTS_PP_API_RMS 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 "TMS-API: RMS Process Parameters" 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_RMXTS_PP_API_RMS TYPE RMXTS_PP_API_RMS.
The RMXTS_PP_API_RMS table consists of various fields, each holding specific information or linking keys about TMS-API: RMS Process Parameters data available in SAP. These include RECN (Sequential Number of Data Record), ACTN (Sequential Number of the Change State), RECNROOT (Sequential Number of Data Record), RMS_CLASS (Process Parameter Class)...
