Custom Popup in VA01 after Availability check
I have to provide a popup message in VA01 (main screen) after the material availability check when user press "Continue" in case the confirmed quantity is less than input quantity. I tried to use:
Program RV03VFZZ --> FORM USEREXIT_AVAILABILITY_IN USING VALUE(US_ATPPR) and
FORM USEREXIT_AVAILABILITY_OUT USING VALUE(US_ATPPR)
but I am unable to trace the field (variable) contaning confirmed quantity. Question is: Is this right place for this if not then how can this be achieved (user-exit, BADI or any other enhancement spot).
