What is the Organizational Structure in SAP MM 2025?
The Organizational Structure in SAP MM refers to how a company’s business units are represented within the SAP system. It defines how various departments, divisions, and processes are linked for smooth business operations.
In simple terms, it’s the digital blueprint of your company in SAP. It shows how different parts of your organization — such as plants, storage locations, and purchasing departments — are connected to each other.
This structure helps SAP understand:
-
Who is buying the materials
-
Where the materials are stored
-
Which company codes or plants are involved
-
How financial transactions should be recorded
Key Elements of Organizational Structure in SAP MM
Let’s understand the main elements that make up the SAP MM Organizational Structure:
1. Client
The Client is the highest level in the SAP system. It represents an entire group of companies or an enterprise. All company codes, plants, and purchasing organizations exist under the client.
Example: GTR Group can be considered a Client in SAP.
2. Company Code
A Company Code represents an independent legal accounting unit where a complete set of financial statements like Profit & Loss and Balance Sheet are prepared.
Example: GTR India Pvt. Ltd. could be a company code.
3. Plant
A Plant is an important element in SAP MM. It can represent a manufacturing unit, warehouse, or distribution center where materials are managed.
Example: The GTR Manufacturing Plant in Mumbai can be one of the plants.
4. Storage Location
A Storage Location is a subdivision of a plant. It specifies where the materials are physically stored within a plant.
Example: Raw materials and finished goods can be kept in separate storage locations in the same plant.
5. Purchasing Organization
The Purchasing Organization is responsible for buying materials and services for one or more plants. It negotiates prices, terms, and conditions with vendors.
Example: GTR Central Purchasing Department handles procurement for all plants.
6. Purchasing Group
A Purchasing Group represents a buyer or group of buyers responsible for specific purchasing activities. It’s more of a personal or departmental responsibility level.
How to Configure Organizational Structure in SAP MM
The configuration of the organizational structure in SAP MM is done step-by-step through the SAP IMG (Implementation Guide). This process is known as SAP MM – Organizational Structure Configuration.
Here’s a simplified overview of the configuration steps:
-
Define Company Code – Create a unique company code in the SAP system.
-
Define Plant – Assign plants to the company code.
-
Define Storage Locations – Create storage locations under each plant.
-
Define Purchasing Organization – Set up purchasing organizations and assign them to the company code or plant.
-
Define Purchasing Groups – Create purchasing groups for buyer responsibility.
After defining all these elements, you link them together through assignments. For example:
-
Assign plant to company code
-
Assign purchasing organization to company code and plant
-
Assign storage locations to plants
Once the configuration is complete, SAP can accurately map all transactions to the correct business units.
