Deletion

Hi Folks,

Does the delete statement works only for internal tables?

I want to delete some entries from a ztable.

TABLES:ZMM__DER.

SELECTION-SCREEN BEGIN OF BLOCK B1 WITH FRAME TITLE TEXT-001.

SELECT-OPTIONS: S_DATE FOR ZMM_DER-RUNDAT OBLIGATORY,

SELECTION-SCREEN END OF BLOCK B1.

DELETE ZMM_DER WHERE RUNDAT IN S_DATE.
