In today’s manufacturing and supply chain operations, businesses often hire outside vendors to do certain tasks in the production process. Companies don’t make every part themselves. Instead, they send raw materials to subcontractors who do certain tasks and then send the finished or semi-finished goods back. To handle this process well, you need a strong enterprise system. This is where SAP Materials Management (SAP MM) comes in.
People who work in procurement, supply chain, and SAP consulting need to know how the SAP MM subcontracting process works. The process of subcontracting makes sure that raw materials sent to vendors are tracked correctly, finished goods received are monitored, and accounting entries are correct.
Learning this process is an important part of Understanding the SAP MM and putting it into practice for students taking a SAP MM module course. Understanding subcontracting will help you deal with real-world business situations, whether you are getting SAP training and certification or going to SAP MM module training.
In this blog, we’ll go over the Subcontracting process in SAP MM step by step, with examples, accounting entries, best practices, and answers to common questions.

What Does It Mean to Subcontract in Understanding the SAP MM?
In SAP MM, subcontracting is when a company sends raw materials or parts to a vendor outside of the company. The vendor takes care of these materials and sends back a finished or partially finished product.
In this setup:
- The company owns the materials it uses.
- The vendor makes or puts things together.
- The business only pays for the subcontracting service.
Many businesses, such as electronics, cars, textiles, and pharmaceuticals, use this process a lot.
Example
A maker of mobile phones sends:
- Printed circuit boards
- Units of display
- Batteries
to a subcontractor who puts the phone together and sends it back.
SAP helps keep track of:
- Materials sent to the vendor
- Amount used in production
- Goods that were sent to us by the vendor
This whole process is what makes up the SAP MM subcontracting process flow.
Important Parts of the SAP MM Subcontracting Process
Businesses can benefit from the subcontracting process in many ways.
Key Features
• Full access to materials sent to vendors
• Automatic use of parts
• Keeping track of stock accurately
• Works with accounting
• Good management of vendors
Because of these features, subcontracting is a main topic in both SAP MM course programs and professional SAP learning tracks.
Step-by-Step Guide to the Subcontracting Process in SAP MM
Let’s look at the step-by-step process to better understand the SAP MM Subcontracting Process Flow.
Step 1: Make a Purchase Order for Subcontracting
The first step is to make a Subcontracting Purchase Order (PO).
Transaction Code: ME21N
This purchase order:
- Uses Item Category L for subcontracting
- Includes the description of the finished material
- Selects the subcontractor vendor
- Links the Bill of Materials (BOM) for components
Important Information in the PO
- Vendor details
- Material to be produced
- Required quantity
- Components to be supplied
- Delivery date
This purchase order gives the subcontractor written instructions to produce the material.
Step 2: Provide Raw Materials to the Vendor
After creating the subcontracting PO, the company sends raw materials to the vendor.
Transaction Code: MB1B or MIGO
Movement Type: 541
At this stage:
- Raw materials are issued to the subcontractor.
- Stock is transferred from company inventory to vendor stock.
Important Note
Even though the materials are at the vendor location, the company still owns them.
Step 3: Vendor Processes the Materials
The subcontractor produces the final product using the provided components.
Example
A furniture manufacturer sends:
- Wooden panels
- Screws
- Polish
to a subcontractor who assembles the furniture.
This step occurs outside the SAP system, but the subcontracting order tracks it.
Step 4: Receiving the Finished Product
Once production is complete, the subcontractor sends finished goods back to the company.
Transaction Code: MIGO
Movement Type: 101
During Goods Receipt
- Finished goods are received into company inventory.
- Components are automatically consumed according to the BOM.
Step 5: Invoice Verification
After delivering the finished product, the vendor sends an invoice for subcontracting services.
Transaction Code: MIRO
The invoice usually includes:
- Processing charges
- Assembly charges
- Labor costs
The company pays only for the subcontracting service, since materials were already supplied.
Subcontracting in SAP MM with Accounting Entries
Accounting entries are created during Goods Receipt and Invoice Posting.
When Goods Are Received
Debit: Inventory Account
Credit: GR/IR Clearing Account
This entry records the receipt of finished goods.
When Posting an Invoice
Debit: GR/IR Clearing Account
Credit: Vendor Account
This entry records the subcontractor’s service charges.
SAP professionals preparing for SAP MM subcontracting interview questions must understand these entries.
Example of the Subcontracting Process in SAP MM
Let’s consider a real-world example.
A company manufactures LED lights but outsources the assembly process.
Materials Sent to Vendor
- LED chips
- Plastic casing
- Wiring components
Subcontracting Process
- Purchase order created for LED assembly
- Components sent to the vendor
- Vendor assembles LED lights
- Finished goods returned
- Invoice paid for assembly services
SAP tracks every step, ensuring complete supply chain transparency.
SAP Subcontracting vs Standard Procurement
| Aspect | Standard Procurement | SAP Subcontracting |
|---|---|---|
| Materials Provided | Vendor supplies materials | Company supplies materials |
| Production Responsibility | Vendor | Vendor using company materials |
| Cost Structure | Total product cost | Processing/service cost |
| Inventory Tracking | Limited | Detailed component tracking |
This comparison explains why special configuration is required for subcontracting in SAP MM.
Documents Used in SAP MM Subcontracting
Several documents are created during the subcontracting cycle.
Important Documents
• Subcontracting Purchase Order
• Component Transfer Document
• Goods Receipt Document
• Vendor Invoice
Many learners use Subcontracting Process in SAP MM PDF, SAP subcontracting process PPT, or SAP MM Training materials to study this topic.
Best Practices for Managing Subcontracting in SAP
Effective subcontracting management requires accurate data and proper planning.
Best Practices
1. Maintain Accurate BOM
Incorrect BOM entries can cause incorrect component consumption.
2. Monitor Vendor Stock
Track materials stored at subcontractor locations.
3. Enable Automatic Consumption
Configure automatic component deduction during goods receipt.
4. Track Vendor Delivery Performance
Monitor vendor lead time and service performance.
5. Train SAP Users Properly
Employees should understand subcontracting transactions and processes.
Most professional SAP training and certification programs cover these best practices.
Why Learning SAP MM Subcontracting Is Important
Anyone who wants to build a career in SAP Materials Management must understand subcontracting.
Career Benefits
• High demand for SAP MM consultants
• Better understanding of supply chain processes
• Increased job opportunities in manufacturing companies
• Strong foundation for SAP consulting roles
Many training institutes include this topic in their SAP MM Course curriculum to prepare students for real-world projects.
