validation on i/o box
I have one i/o box in module pool pro.,
And user should be allowed to enter ALPHABETs ( A to Z)
but not the NUMBERs ( 0 to 9 ).
For this I defined the field's format as STRG in screen attributes.
But as soon as i execute the Tcode for this module pool , it gives runtime error as CONVERSION_FAILED_ERROR..
Could anybody suggest me the solution...
