11i AP - Different Liability Account noticed at Invoice header and Supplier Pay site
I have noticed that an Invoice that is paid, showing different Liability Account at Invoice header and supplier pay site. I did check few more invoices for the supplier but some are having this issue. Some of them are matched to Receipts and some are not.
Unable to understand the reason. Tested in the test instance and noticed that while creating invoice it takes Liab Acct from supplier pay site as required. but in production instance it is not showing different accounts at inovice and supp pay site
Please help and suggest what can be done to correct this issue
