Min-Max planning replenishing a purchase request is the task that requires manual execution of the Process Supply Chain Orchestration Interface process so that a supply order gets created. Min-Max planning is a method of inventory replenishment that maintains a minimum and maximum quantity of each item in a warehouse or subinventory. When the quantity of an item falls below the minimum level, a purchase request is generated to replenish the item to the maximum level1. The purchase request is then sent to the Supply Chain Orchestration Interface table, where it waits for the Process Supply Chain Orchestration Interface scheduled process to run. This process creates a supply order based on the purchase request and sends it to the supplier2. You must run this process manually or schedule it to run periodically3.
