This document is about how missing parts check work in SAP MM Inventory Management.
Overview Of Missing Parts Check:
By using Missing parts check, the system checks at the time of goods receipt, other receipts or transfer posting of a material, whether it is a massing part or not.

What is Missing Part:
A material is called as missing part when the available stock of that material is not sufficient to fulfill the existing reservations (requirements) of that material. So in order to fulfill those requirements you have to procure or produce that material. These requirements may be generated automatically (for ex: by means of Production order dependent requirements for raw materials which will create a reservation for raw materials) or Manually (For Ex: by means of reservation created manually in MB21 with movement type 201 goods issue to cost center).
