Hello,
I hope you were able to resolve this issue since posting this forum, but if not did you try running Sales Reconcile on the Document with the issue?
1. (Sales >> Utilities >> Reconcile-Remove Sales Documents)
2. Enter your Sales Order in the From and To Range.
3. Select the 'Reconcile Sales Documents' Option
4. Mark the option to 'Print Report Only' (this way it will print a report of what will change if you process the reconcile but will not commit those changes.
5. Click Process.
If you see changes that appear relevant, repeat the process without clicking the 'Print Report Only' option to process them.
Otherwise, I would be suspicious of a field such as the quantity previously invoiced in the SOP10200 table for the Sales Order being incorrect and needing to be updated.
select QTYPRINV,* from SOP10200 where SOPNUMBE = 'XXXXXXX'
I hope this helps! If you are in a time crunch, I would recommend opening a support case so we can help you directly if you have not already.
Thanks!
