Do you have the same No. Series being utilized by multiple document types? i.e Sales Order, Sales Invoice, Posted Sales Invoice having the same No. Series? This caused the same issue for us.
There may be an issue with your no. series. Check your no. series and see if the next numbers are correct.
This i s the error message vi get when we try to post the Sales quote. We can fix it manually, but that is not a safe road to continue.
Can you send us the screenshot of the message?
