Compute Material Requirements
Use the Compute Material Requirements screen to plan product requirements by comparing the requested quantity of a list of end parts and their components to existing inventory, order, requisition, and reservation information.
The process plans material requirements in a top-down fashion, exploding the Manufacturing Bill of Material and determining the requirements for each subassembly and component. For each end part, one BOM level at a time, the system determines the new requirements for the part, adds them to existing requirements (including safety stock and inventory requests, if desired), and subtracts current inventory, on-order, and on-requisition quantities. If a shortage is identified, the process can generate a manufacturing order (for make parts) or a purchase requisition (for buy parts) to cover the shortage quantity.

Use the Compute Material Requirements screen to plan products even though their bill of material may not be completed.
After you generate requisitions, manufacturing orders, and/or reservations for a list of end parts, save the run parameters to check the status of a given production job.
Inventory Project Selection Options
You can use the Inventory Project Selection group box to select which projects will be checked when determining current inventory availability.
Below are listed the key part and BOM key characteristics and how they affect the explosion and planning process.
This section describes the different quantity fields found in the Material Requirements Report (MRR) and how they are calculated.
