CVC deletion from file

Dear Experts,

This might be an oft asked question. Posting in hurry without checking first

Why doesn't / didn't SAP provide the standard option of delete CVC's from file on the same lines as create CVC''s from file / work-list.

Can something go wrong if I write my own program to delete CVC's from file ?. I was wondering if SAP didn't provide the same, there must be some hidden danger here that tiny lil minds can overlook..

Please advise

Thanks

BS.
