• What is the cause and solution for SAP error message /SCWM/ERPINTEGRATION016 - The logical system for &1 is not unique ?

  The SAP error message /SCWM/ERPINTEGRATION016 indicates that there is a problem with the logical system configuration in the SAP system. Specifically, it means that the logical system for the specified object (represented by &1) is not unique, which can lead to issues in data integration between the SAP Extended Warehouse Management (EWM) and the ERP system.
  Cause:
  
  Duplicate Logical Systems: The error typically arises when there are multiple entries for the same logical system in the configuration. This can happen if the logical system name is not unique across different clients or systems.
  Incorrect Configuration: The logical system may not be properly configured in the system settings, leading to ambiguity in identifying the correct logical system.
  Transport Issues: If the logical system was transported from one environment to another (e.g., from development to production), it may have been duplicated or incorrectly set up.
  
  Solution:
  
  
  Check Logical System Configuration:
  
  Go to transaction SPRO and navigate to the following path:
  SAP Customizing Implementation Guide -> Logistics Execution -> Extended Warehouse Management -> Integration with ERP -> Define Logical Systems
  
  Verify that the logical system names are unique and correctly configured.
  
  
  
  Identify Duplicates:
  
  Use transaction SE11 to check the table TLOGO (Logical System Table) for any duplicate entries. Ensure that each logical system is unique.
  
  
  
  Adjust Logical System Names:
  
  If duplicates are found, you may need to rename or delete the duplicate logical systems to ensure uniqueness.
  
  
  
  Check Client Settings:
  
  Ensure that the logical system is correctly assigned to the appropriate client. You can check this in transaction SCC4.
  
  
  
  Transport Management:
  
  If the issue arose after a transport, check the transport logs to ensure that the logical system was transported correctly and that no duplicates were created during the process.
  
  
  
  Reconfigure Integration Settings:
  
  If necessary, reconfigure the integration settings between EWM and ERP to ensure that the correct logical system is being referenced.
