• What is the cause and solution for SAP error message UDM_CUST045 - Company code &1 and &2 are in two different logical systems ?

  The SAP error message UDM_CUST045 indicates that there is a mismatch between the company codes being used in a transaction or configuration. Specifically, it states that the two company codes involved are in different logical systems. This typically occurs in scenarios where data is being transferred or integrated between different SAP systems or clients.
  Cause:
  
  Different Logical Systems: The error arises when the company codes referenced in a transaction or configuration belong to different logical systems. Each logical system in SAP represents a separate instance of an SAP system (e.g., different clients or environments).
  Configuration Issues: There may be incorrect configuration settings in the system that define how company codes are linked to logical systems.
  Data Transfer Issues: If you are trying to transfer data (e.g., through ALE/IDoc), the source and target company codes must belong to the same logical system.
  
  Solution:
  
  
  Check Logical System Configuration:
  
  Go to transaction SCC4 to check the logical system settings for the company codes involved. Ensure that both company codes are configured under the same logical system if they are meant to interact.
  
  
  
  Review Company Code Assignments:
  
  Use transaction OBY6 to check the assignment of company codes to the logical systems. Ensure that the company codes are correctly assigned to the intended logical system.
  
  
  
  Data Transfer Settings:
  
  If you are working with data transfer (e.g., using ALE), ensure that the distribution model is correctly set up. Use transaction BD64 to check the distribution model and ensure that the company codes are correctly defined.
  
  
  
  Consult Documentation:
  
  Review SAP documentation or consult with your SAP Basis or functional team to ensure that the configuration aligns with your business processes.
  
  
  
  Testing:
  
  After making any changes, perform tests to ensure that the error does not reoccur and that the transactions or data transfers work as expected.
  
  
  
  Related Information:
  
  Logical Systems: Logical systems are defined in transaction SALE under the "Logical Systems" section. They are used to identify different SAP systems in a landscape.
  ALE/IDoc: If you are using Application Link Enabling (ALE) or Intermediate Documents (IDocs) for data transfer, ensure that the configuration is correct and that the necessary mappings are in place.
  SAP Notes: Check for any relevant SAP Notes that may address specific issues related to this error message or provide additional guidance.
  
  If the issue persists after following these steps, it may be beneficial to engage with SAP support or your internal SAP team for further investigation.
