Mass deletion of analysis authorizations in BW 7.0

Hello all,

since there is no mass maintenance tool in BW 7.0 (especially for deleting AAs), is it safe to write a small ABAP program that deletes the contents from the related tables, e.g.:

DELETE * FROM RSECVAL WHERE TCTAUTH <> '0BI_ALL';

DELETE * FROM RSECHIE WHERE TCTAUTH <> '0BI_ALL';

DELETE * FROM RSECTXT WHERE TCTAUTH <> '0BI_ALL';

Did I miss something? Any other relations?

Thanks in advance!
