A project invoice was created from the billable lines on a project thru the standard create invoice process. The invoice was then cancelled (Correct>Cancel).
Looking at the project, the Billable totals are correct but when you attempt to recreate the invoice you get "Qty. to Transfer to Invoice may not be lower than 0 and may not exceed 0".
How do we recreate the invoice without having to re-establish the billable planning lines (which in turn would double the Billable totals on the project)?
Thanks
