MM Goods Receipt and Goods Issue Part 1: Goods Movements, Movement Types and Stock Types

Key takeaway

Every quantity change in inventory is a goods movement posted with a movement type. Learn MIGO, material documents and accounting documents, the key movement types for receipts, issues, transfers and returns, and the stock types unrestricted, quality inspection and blocked.

What this complete series covers

Learn Goods Receipt and Goods Issue in a clear, practical sequence — from the basic idea to real project use, troubleshooting, and interview-ready understanding.

Who it is for: Best for SAP consultants, developers, and learners who want a practical understanding of Goods Receipt and Goods Issue.
Prerequisites: Basic SAP S/4HANA navigation and an understanding of the business process are helpful. Configuration or transaction steps require suitable access to a practice or project system.
Final outcome: By the end, you should be able to explain Goods Receipt and Goods Issue clearly, follow the main end-to-end flow, apply it in a project scenario, and troubleshoot the most common issues.

Explanation

📌 KEY POINTS
✅ Goods movements are posted with MIGO (or from other processes) using a movement type.
✅ Each movement creates a material document; valuated movements also create an accounting document.
✅ Key movement types: 101 GR for PO, 102 reversal, 122 return to supplier, 201/261 goods issue to cost center/order, 311 transfer, 551 scrapping, 601 delivery.
✅ Stock types: unrestricted, quality inspection, blocked — only unrestricted can be issued normally.
⚠️ Choosing the wrong movement type posts to the wrong accounts and is hard to unwind.

Real project scenario

A warehouse used 501 (receipt without PO) for supplier deliveries because PO numbers were missing on delivery notes. Stock and valuation came in at standard values, invoices couldn't match, and GR/IR had no entries. Requiring PO references (or inbound deliveries) and blocking 501 for most users fixed the three-way match.

Common mistakes

Wrong movement types.
Using 501 instead of PO receipts.
Issuing from quality/blocked stock.
Reversing with a new movement instead of x+1.
Ignoring accounting documents.

Best practices

Restrict movement types by role.
Receive against POs.
Use stock types deliberately.
Reverse with standard reversal types.
Review MB51 regularly.

Interview angle

Questions: "What is a movement type?", "Which movement types do you know?", "What stock types exist?"
Strong answer: MIGO, material/accounting documents, key movement types by category, stock types and transfers.

Practice this lesson

Quick check

1. A company wants to receive materials from a vendor into a stock status that prevents usage or invoice verification until quality or procurement approval is granted. Which movement type accomplishes this during goods receipt?

2. In standard SAP MM procurement processing, which movement type is used to post a goods receipt against a purchase order into unrestricted-use stock?

3. Which movement type posts a goods issue to a cost center?

Interview questions

1. Walk through the end-to-end process and accounting impact when a return delivery to vendor is posted against a goods receipt that was already counted in a completed physical inventory cycle.

Answer it in your own words first, then compare.

2. What is the purpose of an inbound delivery in SAP MM, and how does its document type configuration influence downstream goods receipt processing?
