SAP MM Intercompany STO: A Comprehensive Guide

Nov 18, 2025 by Alex Braham 47 views

Hey guys! Ever wondered how to manage stock transfers between different companies within your SAP system? Well, you're in the right place! This guide dives deep into the Intercompany Stock Transfer Order (STO) process in SAP MM, making it super easy to understand. Let's get started!

Understanding Intercompany Stock Transfer Orders

First off, let's break down what an Intercompany STO actually is. An Intercompany Stock Transfer Order is essentially a purchase order. It's used to move materials from one company code to another within the same organization. Think of it as moving goods between different branches of the same company, even if they're legally separate entities. This process is crucial for businesses that need to redistribute stock efficiently across their various locations or business units.

The beauty of using Intercompany STOs lies in their ability to streamline the transfer process. Instead of treating these transfers as regular sales and purchases (which would involve a lot more paperwork and financial reconciliation), the Intercompany STO simplifies things. It allows for a more controlled and transparent movement of goods, which is particularly useful when you want to keep a close eye on inventory levels and costs across your entire organization.

The key benefits of using Intercompany STOs include:

Simplified Process: Reduces the complexity compared to standard sales and purchase scenarios.
Cost Efficiency: Minimizes unnecessary costs associated with external sales and purchases.
Inventory Control: Provides better visibility and control over stock levels across different company codes.
Accurate Tracking: Enables precise tracking of goods movement, ensuring accountability and reducing discrepancies.
Internal Compliance: Facilitates adherence to internal policies and procedures for stock transfers.

To make the most of Intercompany STOs, it's important to understand the underlying configurations and steps involved. We're going to walk through each of these, so you'll be a pro in no time!

Setting Up the Intercompany STO Process in SAP MM

Alright, let's get our hands dirty with the setup! Configuring the Intercompany STO process in SAP MM involves several key steps. Each step is crucial to ensure a smooth and accurate transfer of goods between company codes. Don't worry; we'll break it down piece by piece.

1. Define Shipping Data for the Supplying Plant

First things first, we need to define the shipping data for the plant that will be supplying the goods. This involves setting up the necessary shipping point and customer master data. The shipping point is the location within the plant from where the goods are dispatched. It's like the loading dock where the trucks come to pick up the shipment.

Go to SPRO (SAP Customizing Implementation Guide).
Navigate to: Logistics Execution -> Shipping -> Basic Shipping Functions -> Shipping Point and Goods Receiving Point Determination -> Assign Shipping Points. Here, you'll assign shipping points to your plants and storage locations based on various criteria such as shipping condition, loading group, and plant.

Next, we need to create a customer master record for the receiving company code. This customer master will represent the receiving company as a customer of the supplying company. Make sure to maintain all the relevant details like address, contact information, and shipping instructions.

Use transaction code XD01 to create a new customer master.
Enter the receiving company code as the sales organization.
Maintain the necessary data in the General Data, Company Code Data, and Sales Area Data tabs.

2. Configure the Purchasing Organization

Next up is configuring the purchasing organization. The purchasing organization is responsible for procuring goods and services for the company. In the case of Intercompany STOs, the purchasing organization in the receiving company code will create the purchase order to request the goods from the supplying plant.

Go to SPRO.
Navigate to: Enterprise Structure -> Definition -> Materials Management -> Define Purchasing Organization. Here, you'll define your purchasing organization and assign it to the relevant company code.

3. Set Up the Supplying Plant as a Vendor

Now, we need to set up the supplying plant as a vendor in the receiving company code. This vendor master record will represent the supplying plant as a supplier to the receiving company. It's similar to how we created a customer master in the supplying company for the receiving company.

Use transaction code XK01 to create a new vendor master.
Enter the supplying plant as the vendor.
Maintain the necessary data in the General Data, Company Code Data, and Purchasing Data tabs. In the Purchasing Data tab, make sure to enter the purchasing organization you defined earlier.

4. Define the Document Type for the Stock Transfer Order

Defining the document type for the stock transfer order is essential. This document type will differentiate the Intercompany STOs from other types of purchase orders in the system. It allows you to apply specific settings and controls to these transfers.

Go to SPRO.
Navigate to: Materials Management -> Purchasing -> Purchase Order -> Define Document Types. Here, you can create a new document type specifically for Intercompany STOs. You can copy an existing document type (like NB – Standard Purchase Order) and modify it to suit your needs. Ensure the item category is set to "U" for stock transfer.

5. Configure Delivery Type and Assign to Document Type

Configuring the delivery type and assigning it to the document type ensures that a delivery is automatically created when the stock transfer order is created. This streamlines the shipping process and ensures that the goods are dispatched promptly.

Go to SPRO.
Navigate to: Materials Management -> Purchasing -> Purchase Order -> Set Up Stock Transport Order -> Define Shipping Control -> Define Delivery Type. Here, you'll define the delivery type (e.g., NLCC – Intercompany Stock Transfer). Then, assign this delivery type to the document type you created in the previous step.

6. Set Up Pricing Procedure

Setting up the pricing procedure is critical for determining the transfer price between the company codes. The transfer price is the price at which the goods are transferred from the supplying plant to the receiving plant. This price can be based on various factors, such as cost, market price, or a negotiated price.

Go to SPRO.
Navigate to: Materials Management -> Purchasing -> Conditions -> Define Price Determination Process -> Define Pricing Procedure. Here, you'll define a pricing procedure specifically for Intercompany STOs. You can include condition types like Intercompany Price (PI01) to determine the transfer price.

7. Assign the Delivery Type to the Supplying Plant and Receiving Plant

This assignment ensures that the correct delivery type is used when creating deliveries for Intercompany STOs. This step links the shipping process to the specific plants involved in the transfer.

Go to SPRO.
Navigate to: Materials Management -> Purchasing -> Purchase Order -> Set Up Stock Transport Order -> Define Shipping Control -> Assign Delivery Type. Here, you'll assign the delivery type (NLCC) to the supplying plant and the receiving plant.

8. Activate the Stock Transport Order Document Type for One-Step or Two-Step Procedure

Activating the stock transport order document type for either a one-step or two-step procedure determines how the goods receipt is handled. In a one-step procedure, the goods are immediately received into the receiving plant's stock upon shipment. In a two-step procedure, the goods are first received into a transit stock and then moved into the receiving plant's stock. The choice depends on your organization's requirements and control needs.

Go to SPRO.
Navigate to: Materials Management -> Purchasing -> Purchase Order -> Set Up Stock Transport Order -> Activate Stock Transport Order Document Type. Here, you'll activate the document type for either the one-step or two-step procedure based on your business needs.

Executing the Intercompany STO Process in SAP MM

Now that we've got the configurations out of the way, let's walk through the actual execution of the Intercompany STO process. This involves creating the purchase order, creating the delivery, performing the goods issue, and finally, the goods receipt.

1. Creating the Stock Transfer Order (Purchase Order)

The first step is to create the stock transfer order in the receiving company code. This is done using transaction code ME21N. Here’s how you do it:

Open transaction ME21N.
Select the document type you defined for Intercompany STOs.
Enter the supplying plant in the Vendor field.
Enter the material number, quantity, and delivery date.
In the Plant field, enter the receiving plant.
Save the purchase order. This will generate a purchase order number.

2. Creating the Delivery

Next, we need to create a delivery for the stock transfer order. This is done in the supplying plant using transaction code VL10B or VL10D, which are used to create deliveries based on the STO.

Open transaction VL10B or VL10D.
Enter the purchase order number or selection criteria to find the STO.
Select the line item and click on Create Delivery.
In the delivery document, enter the storage location and pick the quantity.
Save the delivery. This will generate a delivery number.

3. Performing the Goods Issue

Now, we need to perform the goods issue for the delivery. This is done in the supplying plant using transaction code VL02N. Performing the goods issue reduces the stock in the supplying plant and updates the stock in transit.

Open transaction VL02N.
Enter the delivery number.
Click on Post Goods Issue.
The system will update the stock quantities and create accounting documents.

4. Performing the Goods Receipt

Finally, we need to perform the goods receipt in the receiving plant. This is done using transaction code MIGO. Performing the goods receipt increases the stock in the receiving plant and completes the stock transfer process.

Open transaction MIGO.
Select Goods Receipt and Purchase Order.
Enter the purchase order number.
Verify the material, quantity, and storage location.
Click on Post.
The system will update the stock quantities and create accounting documents.

Troubleshooting Common Issues

Even with the best configurations, you might run into some snags. Here are a few common issues and how to tackle them:

Issue: Delivery cannot be created.
- Solution: Check if the shipping data is correctly maintained for the supplying plant and the receiving plant. Also, ensure that the delivery type is correctly assigned to the document type and the plants.
Issue: Goods issue fails.
- Solution: Verify that the stock is available in the supplying plant and the storage location specified in the delivery. Also, check for any blocking indicators on the material.
Issue: Goods receipt fails.
- Solution: Ensure that the purchase order number is correct and that the material and quantity match the purchase order. Also, check for any quality inspection requirements that might be blocking the goods receipt.
Issue: Pricing discrepancies.
- Solution: Review the pricing procedure and condition types to ensure that the transfer price is being determined correctly. Check the condition records for any discrepancies.

Best Practices for Intercompany STO

To make the Intercompany STO process even smoother, here are some best practices to keep in mind:

Regularly Review Configurations: Periodically review your configurations to ensure they align with your business requirements.
