Why does Fishbowl say "Cannot change vendor's currency after orders have been created:"?

This vendor has existing purchase orders, so Fishbowl prevents changing its currency. The currency setting becomes locked once orders exist against that vendor.

What it means

Fishbowl blocks changes to a vendor’s currency once purchase orders have been recorded for that vendor. This prevents the system from having orders in one currency while the vendor record shows a different one.

What to check

The vendor has existing purchase orders (review the vendor’s Purchase Order history or filter the PO list to this vendor).
You’re attempting to edit the Currency field on the vendor record.
If you need a different currency for future orders, consider creating a new vendor record with the desired currency instead of modifying the existing vendor.
