Hi All,

Need inputs on how can we schedule, reserve, pick, ship... basically orchestrate a sales order without enabling GOP( No Sourcing Rule, Assignment set, ATP Rule...).

Whenever an order is submitted, scheduling fails with "The item passed to order promising was not found in any organization. Verify the item definition. (DOO-2685268)"

I tried creating a custom orchestration process with manual scheduling, but still getting the same error when scheduled manually. Please advice. 

Regards,

Zia
