I am using the Badi INVOICE_UPDATE and method - CHANGE_AT_SAVE to give the error message when the GR quantity is greater than the invoiced quantity comparing the RSEG table and RSEG_NEW.
My problem is, when I choose single line item and click on simulate button, only one Error message with RED shows up. But when I chose, multiple line item and click on simulate button, Error message with RED and same error message with GREEN shows up.
Also, is it possible to give multiple messges in this INVOICE_UPDATE badi. If so, how to proceed with.
I have searched the net and SCN but have not got the correct solution. Kindly help.
