Once an item is introduced via the item management module, the most common change to the item is list cost and deal changes. The Mass Cost Update screen allows the users to change list cost for multiple items at once. The cost can be managed at the following levels in vendor portal.
At the warehouse level or warehouse network level
At store level or store network level
Globally or chain wide list cost
At the model/zone level
A zone is a group of stores for the specific vendors. For retailers with a large # of stores and heavy DSD operations, the DSD cost is often managed at the zone level.
Vendor portal has extensive functionality in zone management where it allows vendors to manage their own zones. Very often, the companies manage this within their ERP and integrate the zone information into the vendor portal.
