Error message in User Exit

[Former Member]

Hi All,

I wish to put in an error message on a user exit that gets displayed when the user clicks SAVE if the PO Number is blank.

I can get the error message to appear but I want the user to be able to change the PO number after the message appears but the screen is all grey.

Is there anyway I can let the user change the PO Number after the error message has been displayed in the user-exit?

Many Thanks,

Colm

Hello,

Plesae try this function module that enables message to appear in user-exit: PTRM_UTIL_MESSAGE_APPEND

Say me if that do what do you want.

Good Luck.

Hi,

Try keeping po number in chain endchain and do the validation

in the exit.

Hi,

Acoording to me the user should be able to HIT Enter and the system will automatically open for inputs. This is how most of the std sap transactions work.

Hi,

If u display the message as error user will not be able to do any thing. Display the message as information popup using FM AQ_INT_SHOW_MESSAGE_AS_POPUP then u can try below code.

SET PARAMETER ID 'BES' FIELD ur current PO number.

CALL TRANSACTION ME22N.

Please analyze this before implementing as it may cause adverse effects.

Thanks,

This FM seems to do the job for me. However I have one issue. I am doing this in VA01 create and order. Once the error is output how do I stop the rest of the processing and display the screen for inputting.

I solved this issue by just re-calling the screen.

CALL SCREEN '4001'.
