U should show your code of PAI process, but it should be this:

PROCESS PAI.

CHAIN.

FIELD: EKKO-EBELN,

EKKO-LIFNR.

MODULE VALIDATION.

ENDCHAIN.

In VALIDATION you should insert your code for validation

Yes you have to validate in the PAI only,

check in debug mode what is the vendor value you are getting

Hi,

You are correct. You ave to do validation in PAI only.

But just before performing your validation, assign the new value.

What is happening in the current situation is, it is no assigning the new value in the error situation.

Thanks,

Yes, it is is correct to validate in the PAI, but I'm not sure about your problem. Please post the code for the screen flow control of the PAI as well as the module which does the validation.

Hi,

validation is in PAI - correct

use this flow-logic:

FIELD xxx MODULE check_abc ON INPUT.
