Hi... My requirement is based on module pool prgmming . i.e 1st screen input field is konnr when user give value then press enter. then it will go to 2nd screen . in 2nd screen table control wizard is there with diff fields,1st field is again 'konnr' . this 'konnr' field value like 1st screen field value this value should come automatically in display mode like non changeable field before enter values manually in 2nd screen table control..in table control user has no chance to change this field value. and how to validate table control fields?
