I have added custom field in VA01 at line item level. Code in PBO of screen is working fine. BUT it will work when I go to that particlular screen.
But the custom field is not populating in USEREXIT_FIELD_MODIFICATION; which is required for validation..
Standard scrren layout and customd field attributes are same.
I need to change attributes in user exit. Error message on save is not advisable.
Is I am missing something? DO I need to write additional in other user exit?
