• What is the cause and solution for SAP error message LB227 - Define only logical system 1 or destination &2 ?

  The SAP error message LB227, which states "Define only logical system 1 or destination &2," typically occurs in the context of configuring logical systems and their destinations in SAP. This error indicates that there is a conflict in the configuration where both a logical system and a destination are defined for the same purpose, which is not allowed.
  Cause:
  The error is caused by the following scenarios:
  
  Duplicate Configuration: You have defined both a logical system and a destination for the same configuration, which is not permitted. SAP expects either a logical system or a destination, but not both.
  Incorrect Settings: The settings in the relevant configuration tables (like TBD1, TBD2, etc.) may have been incorrectly set up, leading to this conflict.
  
  Solution:
  To resolve the error, you can follow these steps:
  
  
  Check Configuration:
  
  Go to transaction BD54 (or SALE -> Integration with Other SAP Components -> ALE -> Logical Systems -> Define Logical Systems).
  Verify the logical systems defined in your system. Ensure that you have not defined both a logical system and a destination for the same purpose.
  
  
  
  Adjust Settings:
  
  If you find that both a logical system and a destination are defined, you need to decide which one to keep based on your business requirements.
  Remove the unnecessary configuration. If you need to use a logical system, ensure that the destination is not defined, and vice versa.
  
  
  
  Check Related Tables:
  
  Review the relevant tables (like TBD1, TBD2, etc.) to ensure that there are no conflicting entries.
  You can use transaction SE11 to view these tables and check for any inconsistencies.
  
  
  
  Transport Requests:
  
  If you are working in a development environment, ensure that any changes made are included in the appropriate transport requests for consistency across environments.
  
  
  
  Testing:
  
  After making the necessary adjustments, test the configuration to ensure that the error no longer occurs.
  
  
  
  Related Information:
  
  Logical Systems: Logical systems are used in SAP to identify different systems in a distributed environment, especially in scenarios involving ALE (Application Link Enabling) and IDocs (Intermediate Documents).
  Destinations: RFC (Remote Function Call) destinations are used to connect to other SAP systems or external systems.
  Transaction Codes: Familiarize yourself with transaction codes like BD54, SM59 (for RFC destinations), and WE20 (for partner profiles) as they are often used in configuring logical systems and destinations.
  
  If the issue persists after following these steps, consider consulting SAP documentation or reaching out to SAP support for further assistance.
