Creating Credit Note "Project purchase unit has not been specified"

I get this error while trying to create a credit note against a PO.

See attached screenshot.

Can someone tell me what i’m missing? I don’t see anywhere to specify it.

Thanks,

Can you give more information of the PO? Is the PO created from Project module?

Pranav…

Yes the PO originated from a project.

We’ve actually found that we had to create the credit note line manually rather than select it from old invoiced po.
