Any suggestions on this error message? 

There are debit and credit open advances that cannot be automatically matched with the invoice SI ####. Please offset advances not relevant for the Invoice ####, manually in a payment entry window first. 

When creating a posting proposal (IEE Apps 9), RMB header Advance Invoice only shows one available Advance Invoice.  There should be three showing. When I do select that one Advance Invoice that appears, I get the error.

If IFS is expecting a supplier offset, what does it mean by “offset advances not relevant”? 

This is my third question in community… hoping for a response.

If not able to respond, do you have a favorite resource for IFS information you could share? I don’t mind weeding through information or reading 1,000 pages to find the answer I need. 

Thank you in advance if you have an idea on this one.
