What functionality is used to make sales order items available to MRP?

The functionality that makes sales order items available to MRP (Material Requirements Planning) is known as Transfer of Requirements. This process involves transferring the demand generated from sales orders to the planning system so that it can incorporate this information into its calculations for material availability and procurement.

When a sales order is created, it generates a demand for specific materials or products. The Transfer of Requirements functionality ensures that this demand is communicated to the MRP module, which then assesses whether the necessary inventory levels or procurement activities are in place to meet that demand. By integrating this data into the MRP process, the organization can effectively plan for production, manage inventory levels, and ensure timely delivery of products to customers.

In contrast, Inventory Checking focuses on determining current stock levels rather than transferring demand. Allocation Rules are used to manage the distribution of available inventory among various demand sources but do not communicate demands to MRP. Lead Time Confirmation is about verifying the time it takes to fulfill orders, rather than managing the demand scenario in the planning process.
