Hi,

This requires more detailed investigations. If it is a correction invoice this can be connected to invoice reference. It can be connected to matching invoice with purchase order also. You should check both.

Best Regards,

@ronhu did you find a solution? 

@alackas sorry for the late.

I encountered the same issue again, thus I am trying to looking for solution and recall everything we made, hence I found my post.

the issue is due to the zero cost posting lines on Posting Proposal, tab Cost Posting, solution is to remove these lines, then posting would be sucessful. usually this happens when user enter the cost posting lines manually, if it has multiple lines to enter, this error occurs.

hope this help.
