KO01 - Error messages to user

[glauco]

Hi friends.

I closed my post about how to add ZZfields in KO01, ko02, ko03.

Now I need to give error messages when user let a OBBLIGATORY customer ZZfield empty.

I used user exit (EXIT_SAPMKAUF_003 that's called in PAI of new ZZsubscreen) BUT, when I need to give error message because a field is empty, screen become blocked and all fields become gray (non-editable).

PS: What do you think about changing program (customer screen 0340) with access key to object R3TR, PROG, SAPMKAUF ? We lost SAP Support ??? I only want to change a custom screen !!! I think this way I can give error messages without leting screen blocked to user.

thanks.

Hi friends.

I have solved it encoding error message in another exit (EXIT_SAPLRKIO_001).
