Hi experts,
I use VL09 to cancel a delivery and if I run VL09, a canceling material document is created.
I want to show an error message if posting date of a canceling material document is different from that of a original material document.
And I want to show that message before a canceling material document is created.
I already tried the exit 'EXIT_SAPLMBMB_001'.
But 'EXIT_SAPLMBMB_001' is run after a canceling material document is created.
Please, give me an advice.
Thank you.
