• What is the cause and solution for SAP error message /SCWM/IT201 - Logical system for EWM must be different from logical system for ERP ?

  The SAP error message /SCWM/IT201 Logical system for EWM must be different from logical system for ERP typically occurs in the context of SAP Extended Warehouse Management (EWM) when there is a configuration issue related to the logical systems defined in the system landscape. This error indicates that the logical system assigned to the EWM system is the same as the logical system assigned to the ERP system, which is not allowed.
  Cause:
  
  Same Logical System: The logical system for EWM is configured to be the same as the logical system for the ERP system. In SAP, EWM and ERP must have distinct logical systems to ensure proper data exchange and integration.
  Configuration Error: There may be a misconfiguration in the system settings where the logical systems are not set up correctly.
  
  Solution:
  To resolve this error, you need to ensure that the logical systems for EWM and ERP are different. Here are the steps to do this:
  
  
  Check Logical System Configuration:
  
  Go to transaction code SCC4 in the SAP GUI.
  Check the logical system names for both the ERP and EWM systems.
  
  
  
  Define Logical Systems:
  
  If the logical systems are the same, you will need to create a new logical system for EWM.
  Use transaction code BD54 to define the logical systems.
  Ensure that the logical system for EWM is unique and different from the ERP logical system.
  
  
  
  Assign Logical Systems:
  
  Use transaction code SPRO to access the SAP Reference IMG.
  Navigate to Extended Warehouse Management > Master Data > Define Logical Systems.
  Assign the correct logical system to EWM.
  
  
  
  Check RFC Connections:
  
  Ensure that the RFC connections between the ERP and EWM systems are correctly configured.
  Use transaction code SM59 to check the RFC destinations.
  
  
  
  Transport Requests:
  
  If changes are made in a development environment, ensure that they are transported to the quality and production environments.
  
  
  
  Testing:
  
  After making the necessary changes, test the integration between EWM and ERP to ensure that the error does not occur again.
  
  
  
  Related Information:
  
  Logical System Naming Convention: It is a good practice to follow a naming convention that clearly distinguishes between different systems (e.g., ERP_SAP for ERP and EWM_SAP for EWM).
  Documentation: Refer to SAP documentation for detailed steps on configuring logical systems and integration settings.
  SAP Notes: Check for any relevant SAP Notes that may provide additional guidance or updates related to this error.
