Inter-Billing TroubleShooting: Invalid Account No message when create new Invoice

From AutoCount Resource Center

Question: Our Company is using intercompany billing plugin to post IV to PI. When I create a new invoice and save, system prompted ‘Invalid Account No’. The invoice was successfully saved but Purchase Invoice does not post to another account book.

Possible Reason:

In the other account book, the item group of this item is not assigned with Purchase code and the GL default account is not assigned with Purchase account too.
