Stock Transport Order SAP MM

What Is the Difference Between Intra-Company and Inter-Company Stock Transport Orders (STO)? Stock Transport Orders (STOs) are used to transfer materials between plants. The key difference is whether the plants belong to the same company code or different company codes. Scenario 1 – Intra-Company STO Business Process Plant A (Company Code 1000) ⬇️ STO Created (ME21N) ⬇️ Outbound Delivery ⬇️ Goods Issue (GI) ⬇️ Goods Receipt (GR) ⬇️ Inventory Updated Characteristics ✅ Same Company Code ✅ Inventory moves between plants within the same legal entity ✅ No customer invoice is created ✅ No inter-company billing Example Company Code 1000 Plant A → Plant B Both plants belong to Company Code 1000, so only inventory is transferred. Scenario 2 – Inter-Company STO Business Process Plant A (Company Code 1000) ⬇️ STO Created (ME21N) ⬇️ Outbound Delivery ⬇️ Goods Issue (GI) ⬇️ Inter-Company Billing ⬇️ Goods Receipt (GR) ⬇️ Vendor Invoice (Optional, depending on the process) Characteristics ✅ Different Company Codes ✅ Inventory moves between separate legal entities ✅ Inter-company billing is required ✅ Financial postings occur between company codes Example Company Code 1000 ↓ Plant A ↓ Company Code 2000 ↓ Plant B Since each plant belongs to a different legal entity, SAP generates the necessary accounting and billing documents to record the transfer. Key Differences Feature Intra-Company STO Inter-Company STO Company Code Same Different Plants Same Legal Entity Different Legal Entities Billing Not Required Required Accounting Entries Internal Between Company Codes Inventory Transfer Yes Yes Key Takeaway ✔ Intra-Company STO is used when transferring stock between plants within the same company code, making the process simpler with no inter-company billing. ✔ Inter-Company STO is used when transferring stock between plants in different company codes, requiring billing and financial postings between legal entities. Understanding the difference is essential for designing the correct procurement, logistics, and accounting processes in SAP S/4HANA.
