What is an Organizational Structure in SAP MM?
The organizational structure in SAP MM defines how a company is organized in the system for materials management and procurement. It represents different business units, such as companies, plants, storage locations, and purchasing organizations, and how they are connected to each other.
In simple terms, it is the hierarchical setup that controls how materials and purchasing activities are managed across the company. Each level in this structure serves a specific purpose and helps SAP integrate various business processes efficiently.
Why Is the Organizational Structure Important in SAP MM?
The organizational structure helps SAP MM users:
-
Control the flow of materials and goods within the company.
-
Manage purchasing and inventory systematically.
-
Assign responsibilities to different departments and plants.
-
Maintain accurate records of transactions across business units.
-
Generate reports based on specific company codes or plants.
Without a clear structure, it would be difficult to track materials, handle suppliers, or manage purchases efficiently.
Key Components of MM Organizational Structure in SAP
Let’s look at the main elements that form the SAP MM organizational structure:
1. Client
At the top of the hierarchy is the Client.
It represents the highest level in the SAP system and refers to the entire enterprise. Every data or configuration created under a client is accessible to all its company codes and plants.
Example: If GTR Group runs multiple companies under one SAP system, the Client represents GTR Group as a whole.
2. Company Code
The Company Code is the legal entity for which financial statements such as balance sheets and profit & loss accounts are created.
Each company code operates independently but can share data within the same client.
Example: GTR India Pvt. Ltd. and GTR USA Inc. can each have their own company code.
3. Plant
A Plant is a physical or logical location where materials are manufactured, stored, or distributed.
It is a key component in SAP MM because most materials management activities — such as inventory control, material valuation, and purchasing — take place at the plant level.
Example: A factory, warehouse, or distribution center can be a plant.
4. Storage Location
The Storage Location represents specific places within a plant where materials are stored physically.
It helps keep track of stock levels, material movements, and goods receipts at a detailed level.
Example: A warehouse can have separate storage locations for raw materials, finished goods, or spare parts.
5. Purchasing Organization
The Purchasing Organization is responsible for procurement activities such as purchasing materials and negotiating with vendors.
It can serve a single company code or multiple company codes depending on how the company operates.
Example: GTR Academy might have a central purchasing organization that buys materials for all its training centers across different cities.
6. Purchasing Group
The Purchasing Group represents a person or group of people responsible for specific purchasing activities.
It’s more of an operational unit that handles purchase orders and vendor communications.
Example: A purchasing group can be assigned for IT equipment, another for office supplies, and another for training materials.
MM Organizational Structure in SAP – Example
Let’s understand with an example:
Imagine GTR Academy, one of the best SAP training institutes, operates across India.
Its organizational structure in SAP MM can look like this:
-
Client: GTR Academy Group
-
Company Code: GTR Academy Pvt. Ltd.
-
Plant: GTR Bangalore Campus, GTR Delhi Campus
-
Storage Location: Classroom Materials, Lab Equipment, Library Stock
-
Purchasing Organization: GTR Central Procurement
-
Purchasing Group: Trainers Group, IT Group, Admin Group
This setup allows GTR Academy to manage materials like laptops, projectors, books, and other resources efficiently in SAP.
