ACT01_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 ACT01 (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_ACT01_CJDB_REP TYPE ACT01_CJDB_REP.
The ACT01_CJDB_REP table consists of various fields, each holding specific information or linking keys about Reporting str. for ACT01 (for CJDB_GET_PROJECT_FROM_LDB_PSJ) data available in SAP.
