PRPS_CJDB_REP 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 "Reporting str. for PRPS (for CJDB_GET_PROJECT_FROM_LDB_PSJ)" 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_CJDB_REP TYPE PRPS_CJDB_REP.
The PRPS_CJDB_REP table consists of various fields, each holding specific information or linking keys about Reporting str. for PRPS (for CJDB_GET_PROJECT_FROM_LDB_PSJ) data available in SAP. These include POSID (Work Breakdown Structure Element (WBS Element)), POST1 (PS: Short description (1st text line)), OBJNR (Object number), PSPHI (Current number of the appropriate project)...
