What is a Stock Transfer Order (STO)
and How to Configure It in SAP
Introduction: Understanding Stock Transfer Orders in SAP
A Stock Transfer Order (STO) in SAP facilitates the
movement of stock between two plants, either within the same company code
(intra-company) or between different company codes (inter-company). Unlike
traditional transfer postings, STO enables integrated logistics processes
such as delivery, billing, and goods issue/receipt tracking. STOs are crucial
for maintaining accurate inventory records and enabling efficient supply
chain operations.
Step-by-Step Configuration of Stock Transfer Order Between
Two Plants
To successfully configure STO in SAP, the following steps
must be performed:
1. Create a Vendor for the Receiving Plant
-
Use T-Code: BP
-
Select vendor role (e.g., FLVN00 or FLVN01)
-
Assign the vendor to the company code of the receiving
plant
2. Assign Supplying Plant in Vendor Master
-
In the purchasing data view:
-
Define the supplying plant
-
Assign a schema group
3. Create Customer with Vendor's Sales Area
-
Use T-Code: BP
-
Select customer role (e.g., FLCU00 or FLCU01)
-
Align the customer account with the vendor's sales
area
-
This is essential for outbound delivery and billing in STOs
4. Define Route Determination Elements
-
Configure:
-
Shipping conditions

Delivering plant

Transportation zone

These inputs help determine the delivery route for
the STO
5. Configure Pricing Procedure

pricing procedure

STO process

-
Ensure proper condition records are maintained in SAP
7. Maintain Carrier in Customer Master
-
Define the carrier as a partner function in
the customer master
8. Configure Supplying & Receiving Plant Assignments
-
Use T-Code: OMGN
-
Assign company code and sales area to both supplying
and receiving plants
9. Assign Delivery Type and Checking Rule
-
Link the delivery type (e.g., NB) and checking
rule to the STO document type
10. Map Document Type for Supplying/Receiving Plants
-
Define the purchasing document type to be used between
the plants

Inter-Company Stock Transfer in SAP
When stock transfer occurs between plants in different
