I have a requirement in XD02, here after entering the customer number, i need to do some validation and on basis of that validation i want the user to edit customer details or just display everything in display mode only. I found a BTE and got tx XD01 called on the basis of validation and its working fine. However when the user presses the change button, he/she is able to go back into change mode. I want the user not be able to change any customer details at all, based on the validation in TX XD02. Anyhelp would be appreciated.
