Sorry for posting this in general but didnt know wat category this would go in.
The question is suppose i have a select options for materila say s_matnr on the selection scree. I wanna validate it so i put a piece of validation at-sel-screen saying
SELECT SINGLE * FROM mara WHERE matnr IN s_matnr. IF sy-subrc <> 0. MESSAGE e000 WITH text-t06 s_matnr-low text-e01. ENDIF.
But wat if some one enters a multiple selection on the sel screen where the 3rd and the 4th material nos are incorrect. In that case the system is not returning any error message.
Can some one suggest me a better way??
is looping on s_matnr a good option?
