What Does SAP MM Mean?

SAP MM is a main part of SAP ERP that handles purchasing, inventory, and material management.

It helps businesses:

Get materials quickly and efficiently
Keep track of your inventory levels
Keep an eye on vendor transactions
Connect with sales and finance

An Overview of the SAP MM End-to-End Process Flow

The whole process goes through a set cycle:

Finding out what you need
Purchase Requisition (PR), Request for Quotation (RFQ), Vendor Selection, Purchase Order (PO), Goods Receipt (GR), Invoice Verification, and Payment Processing

Let’s go over each step in detail.

SAP MM Process Flow with Codes in Steps

1. Finding Out What is Needed

This is where the need for a material is found.

For example, a company that makes things needs raw materials:

Who raised it: the department or the MRP system
No Code needed yet (first stage)

2. Purchase Request (PR)

PR is a document that asks for procurement within an organization.

TCode: ME51N

Example: The store department asks for 100 pieces of steel.

Important Points:

Document for internal use
No vendor has been chosen yet
It may require approval

3. Request for Quotation (RFQ)

We send RFQs to several vendors to get prices.

TCode: ME41

For example, send an RFQ to three steel suppliers.

4. Vendor Selection and Quotation Comparison

You get quotes from vendors and then compare them.

TCode: ME49

Selection criteria:

Cost
Delivery time
Quality

5. Purchase Order (PO)

PO is a written request that is sent to the chosen vendor.
TCode: ME21N
Example: Order 100 steel units from Vendor A.

Important Information:

Assigned to a vendor
Price finalized
Legal document

6. Goods Receipt (GR)

After the goods are delivered, they are entered into SAP.

TCode: MIGO

For example, receive 100 units in the warehouse.

System Updates:

Stock increases
Accounting entry created

7. Invoice Verification

The vendor sends an invoice that is checked against the PO and GR.

TCode: MIRO

Example: Invoice received for ₹50,000.

Checks:

Amount
Price
Tax

8. Payment Processing

Payment is made through the finance module.

Integrated with: SAP FICO

Example: Payment made via bank transfer.

PR → RFQ → Vendor Selection → PO → GR → Invoice → Payment

This is the standard SAP MM Course flow followed by most companies.

Real-World Example (End-to-End)

Let’s simplify with a practical example:

A construction company needs cement.

PR raised for 500 bags
RFQ sent to vendors
Vendor selected based on price
PO created
Goods delivered to site
Invoice verified
Payment processed

Result: Smooth procurement cycle with proper tracking
