If you choose to Correct a Purchase Invoice (PI) the system automatically creates a Credit PI and a new PI to correct and then post. This new PI cannot be posted 'as is' as the original PI still has the Vendor Invoice No. (VIN) set and this should be unique. The current way around this is to suffix the VIN, e.g. with an underscore (_). This has the disadvantage that when later matching bank statements the corrected PI is not matched.

If the system would suffix the posted PI's VIN instead, that would make life easier as the new PI can be posted 'as is' and matching keeps working.

I know it's possible to turn off this check but I find that undesirable as duplicate documents are sometimes submitted and would then no longer be detected.
