When user tries to edit a vendor record and hit Save button a warning message appears:
You cannot delete currencies that have the specific pricing setup for the entity.
User can try the steps below to be able to save the vendor record:
1. Edit the Vendor record.
2. Under Financial tab > Primary Currency > Change this to the account's base currency.
3. Hit Save.
4. Edit the Vendor record again and change back the primary currency to the original currency of the vendor.
5. Hit on Save.
In case the same warning message is encountered in step 3, try to check if there are items listed on the vendor record's Financial tab > Items sub tab. If there is, Edit the item record and remove the preferred vendor (Edit Item record > Purchasing/Inventory tab > Vendors). After doing this, follow steps 1-5 again. If it saves properly, you can edit the item record again and input the preferred vendor again.
