Overview
Stock transfers between plants or storage locations require accurate valuation, especially when goods are in transit. This guide covers SAP MM configurations, accounting impacts, and solutions to common challenges.
Key Concepts
Movement Types: 301 (Plant-to-Plant), 303 (Storage Location-to-Storage Location)
Stock-in-Transit (SIT): Managed via Movement Type 305
Valuation: Ensures correct GL postings during transfer
Configuration Steps
Define SIT Storage Location (SPRO: MM → IM → Stock Transfer)
Configure Movement Type 305 (Transaction OMJJ)
Set Up Automatic Postings (OBYC for BSX and PRD accounts)
Accounting Impact
Goods Issue (GI): Reduces stock at issuing plant
Goods Receipt (GR): Increases stock at receiving plant
SIT Account: Tracks inventory during transit

Common Issues & Resolutions
Missing SIT in Reports → Include transit storage location in MB5L
Valuation Errors → Verify OBYC settings for BSX/PRD
Batch Transfer Failures → Use MIGO with Movement Type 305
Best Practices
Schedule transfers during off-peak hours
Reconcile weekly using MB5L
Maintain audit logs via SM20
Case Example
A manufacturing client resolved unaccounted stock by implementing Movement Type 305 with automated Fiori analytics, achieving full inventory visibility.
