You are unable to post the cancelation invoice because of an error message: Item X: The item in the document has the same quantity as the item in the reference document, but the price is lower.
Reproducing the Issue
- Go to the Supplier Invoicing work center.
- Select the Invoices and Credit Memos view.
- Select the invoice ABC and select Edit button.
- Select Post button.
- System displays the error message.
System displays the error message due to the change in the Posting Date of the supplier invoice and the cancelation invoice which leads to the different currency conversion rate.
The supplier invoice is created with the currency USD and posted on DD:MM:YYYY (Ex:03.12.2012). The supplier invoice cancelation is posted on DD:MM:YYYY (Ex: 01.01.2013).
Since the Purchase order in reference to which the supplier invoice is created is posted in currency EUR.
So system checks the currency conversion rate according to the posting date.
Since the currency conversion rate changes, system displays the error message.
To avoid this error message post the invoice on the same posting date DD:MM:YYYY (Ex:03.12.2012).
