Hello,

Is your requirement to Validate the Character Field? This is what I understand. If it is right, then do you want to Validate whether a Character Value is entered?

Check the below Sample Code.

At Selection-Screen on P_CHARFIELD.

IF P_CHARFIELD CA '1234567890'.

Message 'Enter an Alpha Character only' Type 'E'.

Endif.
