Dear,
I've matched invoice with 2 product receipts with total quantity 12,000 (2 lots)  and I accidentally changed quantity at invoice line to be 11,000.
This invoice has been posted successfully. 
Then I tried to issue credit note for this invoice but got an error message as attached.
I wonder how can I correct the mistakes? or you have any suggestion for this case? 
Please advise.
Thank you in advance.
