This document provides an overview of SAP MM (Materials Management). It discusses the key components and processes in SAP MM including master data, procurement, inventory management, invoicing, valuation, materials requirements planning, and implementation milestones. The procurement process involves activities from requisitioning to payment. Inventory management covers goods movements, stock updates, and document creation. Invoicing can be done based on purchase order or goods receipt. Valuation determines price and account updates. MRP generates planned orders to fulfill material requirements.

13.  Procurement for stock
 Procurement for stock is characterized by the fact that the material is stored after goods
receipt, and the consumption of the material is entered in a separate step.
If material is procured for stock, the warehouse stock level of the material is increased by
entering goods receipt and reduced by entering goods issue.
 Procurement for consumption
 In the case of procurement for consumption, the material is regarded as consumed at
the time of goods receipt.
If a material is procured for consumption, the consumption purpose is defined by
purchasing (an account assignment category and further specifications such as cost
center or project number are entered).
If material is procured directly for consumption, no warehouse stock is created when
goods receipt is entered (and the stock value is not increased) but the consumption
statistics (and the consumption accounts in the accounting department) are updated
directly.

15. Inventory management is concerned with the flow of materials
within a company.
Goods movements are divided into goods receipts, goods issues, and
transfer postings.
When you enter a goods movement, the stock situation is updated both
on a quantity and value basis . In addition, material documents are
created to record each transaction.

17. In the case of order-based invoice verification, the
items in a purchase order are settled. A prerequisite for this is that
goods receipt has not yet been entered for the quantity invoiced when
invoice verification is carried out. Items from different purchase orders
can be settled together.
With invoice verification based on goods receipt, each
goods receipt is settled individually. The goods receipt must already
have been entered for the quantity invoiced. Different goods receipts
can be settled together. GR-based invoice verification must be
specified in the order item.

19. In the material master for a material with price control S, the
'Moving average price' is also displayed so you can determine the
difference between the acquisition price and the standard price.
Receipts are posted to the stock account with the receipt value Quantity *
Purchase order price. The moving average price is recalculated after every
transaction to correspond to the acquisition price.

21. If a material requirement is automatically planned and
requirements planning is active in the plant, planning mark-outs are
automatically created when transactions relevant for materials planning
are carried out (goods issue, reservations, changes to the materials
planning data…)
Requirements planning can be carried out online or using
background processing.
Planned orders are proposals for the issue of purchase orders to satisfy
a requirement. In a separate step, they are converted into purchase
requisitions.
