Backend error: Quantity 0.20 smaller than quantity delivered 2.00 and purchase order item 10 still contain faulty schedule lines

Hi,

While changing the PO user is getting the below backend error:

Backend error: Quantity 0.20 smaller than quantity delivered 2.00 and purchase order item 007 still contain faulty schedule lines.

user is trying to change some other line item and error is w.r.t different line item.

I have also checked GR and IV for line item 7 , its quantity is 2 in GR and IV both. I have also checked ECC PO the quantity is correctly updated as 2.

We are in extended classic scenario on SRM 7.03.

Please suggest why we are receiving this error.

Thank You.

Best Regards,

Abhishek
