The IDocs are read according to their status values. Since only the last (current) status is relevant for all statistics programs (exception: the evaluation history, evaluation of the test IDoc), the system only accesses the control record table (EDIDC), due to performance reasons - the control record always contains the current IDoc status. Both exceptions mentioned above must read all statuses and therefore access the status record table (EDIDS). For this reason, this program requires more time than the other statistics programs.

The IDocs are assigned to the individual status groups in table TEDS3.
