Cleanup

The TFORM_GENERATE_VALID_COMBINATIONS program cleans up the previously generated records in the SC_VALID_COMBINATIONS as follows:

DELETE FROM SC_VALID_COMBINATIONS vc 
    WHERE valid_combination_source = 'Generated'

    //If source is specified:
    AND source = <SOURCE>

Note:

If the records are successfully deleted or cleared, commits changes.
If an error occurs while deleting the record, the processing is stopped, error message is logged, and returned with error.
The task log record is updated with the actual status.
