Hi, when I save an order by co02, I need to check some data in the position before saving and if something is wrong, then I want to block the saving.
I tried to use the user exit EXIT_SAPLCOBT_001 to do my checks, but after that I cannot avoid the saving.
In the user exit EXIT_SAPLCOZV_001 I have only the header of the order and in this moment I cannot get the operation data not yet saved, but only the data already in the db. How can I get the data that will be saved before the commit? O any help to block the saving?
