Event Proposal
Suppliers now have the ability to create future and past-dated Events directly in Supplier One for Stores and Dotcom. Once approved by both the Merchant and the Supplier, the Event is assigned a Co-op ID. The Co-op start date is determined based on the Event start date, not the collection dates.
In the left navigation menu of Supplier One, click Growth opportunity and select Event proposals. Or navigate directly to https://supplierone.wal-mart.com/coop.
