I am trying to change the Order quantity at item level in VA02 transaction, before saving the documnet i did some validation on this order quantity in the exit userexit_save_document_prepare.
.
if xvbap-kwmeng > ztable-quantity.
xvbap-kwmeng = ztable-quantity.
modify xvbap index sy-tabis.
endif.
Here the new validated value will be updated in VBAP table, but at transaction(VA02) level it is not updated, it is showing old value only.
Even i maintained XVBAP-UPDKZ = 'U'.
But at screen level it is not updating?
Could you please let me know ASAP for my issue....
