PRPS_UPD_VS2OP 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 "Fields from PROJ (sim.vers.) NOT relevant to the update" 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_PRPS_UPD_VS2OP TYPE PRPS_UPD_VS2OP.
The PRPS_UPD_VS2OP table consists of various fields, each holding specific information or linking keys about Fields from PROJ (sim.vers.) NOT relevant to the update data available in SAP. These include MANDT (Client), PSPNR (WBS Element), POSID (Work Breakdown Structure Element (WBS Element)), OBJNR (Object number)...
