We have a issue with confirmed PO appearing in desktop receipt. The shopping cart was created with UOM PCK and the PO was created with UOM PAK. While we see in the system the PAK and PCK UOM conversion exsts in german language. Looks like issue is because of this and the same has been addressed when we raised OSS message.
Now The issue is we are not able to maintain the UOM in english language, when we try doing it in transaction CUNI we get the error: ISO code NMP is already used for measurement PAC.
Please suggest step by step on how to maintain the conversion in english language.
or, any other directions to resolve this issue.
