What is MM Organizational Structure in SAP?
The MM Organizational Structure in SAP defines how a company’s procurement and inventory management activities are organized. It represents the hierarchy or framework that shows how different business units are connected and how they work together in the materials management process.
In simple words, the MM organizational structure tells SAP:
“How is my company divided for purchasing and material management?”
This structure includes various organizational units such as Client, Company Code, Plant, Storage Location, and Purchasing Organization. Each unit plays a unique role in how materials are bought, stored, and managed.
Key Components of MM Organizational Structure in SAP
Let’s understand the main elements that form the organizational structure in SAP MM, step by step.
1. Client
The Client is the highest level in the SAP system.
It represents the entire organization or group of companies.
All data in SAP, such as materials, vendors, and configurations, are stored at the client level and can be shared across all company codes under it.
2. Company Code
A Company Code is a small, independent legal unit within the organization.
It represents a separate accounting entity where all financial transactions like purchasing, payments, and reporting are recorded.
Each company code has its own balance sheet and profit & loss statement.
3. Plant
The Plant is one of the most important organizational units in SAP MM.
It refers to a place where materials are manufactured, kept, or supplied.
A plant can be a manufacturing site, a warehouse, or even a distribution center.
In procurement, all goods receipts, inventory updates, and material storage activities happen at the plant level.
4. Storage Location
Within each plant, there are multiple Storage Locations.
These are physical or logical places where materials are stored.
For example, a plant can have separate storage locations for raw materials, finished goods, or spare parts.
5. Purchasing Organization
The Purchasing Organization is responsible for buying materials and services.
It handles vendor negotiations, purchase order creation, and contract management.
A company can have multiple purchasing organizations depending on how centralized or decentralized their procurement process is.
6. Purchasing Group
A Purchasing Group represents an individual or team responsible for specific purchasing activities.
It is not an organizational unit in the system hierarchy but is used for reporting and authorization purposes.
SAP MM – Organizational Structure Configuration
Now that you understand the components, let’s talk about how the structure is configured in SAP.
Configuration means creating and linking these units properly in the SAP system.
The process is done through SPRO (SAP Project Reference Object) using the following path:
SPRO → Enterprise Structure → Definition → Materials Management
You’ll configure:
-
Plants under Company Codes
-
Storage Locations under Plants
-
Purchasing Organizations and Purchasing Groups
-
Link the Purchasing Organization to the Company Code and Plant
Each connection ensures that materials flow correctly from procurement to inventory management.
If you’re studying this topic for certification, downloading an MM Organizational Structure in SAP PDF or SAP MM Enterprise Structure Configuration PDF can be very helpful for practice and revision.
Example of MM Organizational Structure in SAP
Let’s look at a simple example to make it easier to understand:
Imagine a company called ABC Manufacturing Pvt. Ltd. that has:
-
One Client: ABC Group
-
Two Company Codes:
-
1000 – ABC India Pvt. Ltd.
-
2000 – ABC USA Inc.
-
-
Plants:
-
1100 – Mumbai Plant
-
1200 – Delhi Plant
-
-
Storage Locations:
-
RM01 – Raw Materials
-
FG01 – Finished Goods
-
-
Purchasing Organization:
-
3000 – Central Purchasing Org
-
This example shows how the entire structure connects from top to bottom, ensuring every purchase or inventory activity is linked to a specific plant and company code.
Importance of MM Organizational Structure in SAP
The MM organizational structure is the foundation of the procurement process. Without it, you cannot perform any transactions in SAP. Here’s why it’s so important:
-
Defines how purchasing and inventory are managed.
-
Ensures data consistency across all modules.
-
Helps in financial reporting and tracking material costs.
-
Enables efficient procurement through correct vendor assignments.
-
Supports multiple locations and international operations.
In short, it brings clarity, control, and efficiency to an organization’s supply chain process.
