Key Components of SAP S/4HANA MM

Common activities include:

3. Material Master: Material Master contains important information about materials used by an organization. It includes descriptions, units of measure, purchasing data, storage information, accounting details, and other relevant material attributes.

5. Invoice Verification: Invoice Verification connects purchasing and goods receipt activities with supplier invoice processing. It helps verify invoice details against purchase orders and goods receipts.
SAP S/4HANA MM Procurement Process
The procurement process is one of the most important business processes in SAP MM. It is commonly known as Procure to Pay (P2P) Process.
A standard procurement flow includes:
Requirement → Purchase Requisition → Purchase Order → Goods Receipt → Invoice Verification → Vendor Payment
Here is how each stage works:
- Purchase Requisition: An internal document that communicates the requirement for materials or services.
- Purchase Order: A formal purchasing document sent to the selected supplier.
- Goods Receipt: Records the materials received from the supplier and updates inventory where applicable.
- Invoice Verification: Checks the supplier invoice against the purchase order and goods receipt.
- Vendor Payment: The finance team processes payment to settle the supplier liability.
The exact process may vary depending on the organization’s procurement requirements and SAP configuration.
