Hi bhaskar,

I think this is the error.

replace the first parameter declaration with below line

<b>parameters:p_kunnr type kna1-kunnr modif id ABC user-command RAD.</b>Please reward points if helpful

Thanks,

Hi,

If you press the Enter then only it will show the Disable fields, until unless it will not trigger the Event.

Hi,

when you correct value and press <b>execcte(F8)</b> it goes to at selection screen and then start-of-selection it does not go to at selection screen output event .

so the remainng 3 are not displayed.

when you correct value and press <b>enter</b> it goes to at selection screen and then at selection screen output event then the remainng 3 are displayed.

regards,

anath.
