uppercase in screen.

hi sap,

i have screen with 5 fields and on the first screen field the input must be in UPPER CASE.

I have tried in the attributes but i could not find anything to set. but there is one check box with UPPER CASE and LOWER CASE but it is non-editable mode. i tryed to check the tick box by unticking the check box of FROM DICTIONARY... but when i untick it gives me error.

how can i make it to give only upper case? can you please help me out

this is the table and field name : T024-EKGRP

your help is much appriciated. i have checked in the SDN but i could not find anything.

regards,

laya.
