This has been tested and works on 2.2MS2. For 2.2MS1, it should be compatible, however, have not tested This vendor contribution is the first part in a developing multi-part contribution for vendor, product, inventory purchasing, receiving, and management. The vendor contribution allows you to Add/Edit vendors (no delete, for historical record keeping purposes). It also allows you to add an unlimited amount of vendors to a single product, for those stores who have the ability to get products from different vendors. Deleting a product does not delete the vendor. Deleting a product from a vendor's list does not delete the vendor. Vendor management is in its own Left Nav Admin box. Product mapping to vendors is done when you edit a product, there is a button for "vendors". There is not a customer facing portion to this, this is admin only.
