Cannot Generate Distributions for PO matched invoice lines - Things to check

Summary:

I have an imported invoice with two lines, both PO matched - On one of the invoice lines, I am receiving a hold which states "Cannot Generate Distributions". Based on my various searches, I cannot find anything definitive on this hold, so I wanted to see if anyone has a cheat sheet or checklist on what to troubleshoot around this error or what would cause it. I see a PO Charge Account and project-related information on the PO line/schedule is being matched to so I'm not sure what would be causing this error.
