• What is the cause and solution for SAP error message /PLMU/UI_FRW035 - Logical System &1 is not mapped to a RFC destination ?

  The SAP error message /PLMU/UI_FRW035 Logical System &1 is not mapped to a RFC destination indicates that there is a configuration issue where a logical system is not properly mapped to a Remote Function Call (RFC) destination. This can occur in various scenarios, particularly when working with distributed systems or when integrating different SAP systems.
  Cause:
  
  Missing Mapping: The logical system specified in the error message is not mapped to any RFC destination in the SAP system.
  Incorrect Configuration: The RFC destination may not be correctly configured or may have been deleted or changed.
  Transport Layer Issues: If the logical system is part of a transport layer, it may not have been properly set up in the target system.
  System Landscape Changes: Changes in the system landscape, such as system copies or migrations, may lead to inconsistencies in logical system mappings.
  
  Solution:
  To resolve this error, follow these steps:
  
  
  Check Logical System Configuration:
  
  Go to transaction SM59 (RFC Destinations).
  Look for the RFC destination that corresponds to the logical system mentioned in the error message.
  If it does not exist, you will need to create it.
  
  
  
  Create or Update RFC Destination:
  
  If the RFC destination is missing, create a new one:
  
  Click on "Create" and enter the necessary details (e.g., target host, system number, etc.).
  Ensure that the logical system name matches the one in the error message.
  
  
  If it exists but is not configured correctly, update the settings as needed.
  
  
  
  Check Logical System in T000:
  
  Use transaction SE03 or SE06 to check the logical system configuration in the T000 table.
  Ensure that the logical system is correctly defined and active.
  
  
  
  Transport Configuration:
  
  If the logical system is part of a transport route, ensure that it is included in the transport layer and that the transport routes are correctly defined.
  
  
  
  Testing:
  
  After making the necessary changes, test the RFC connection using the "Test Connection" button in SM59.
  Ensure that the connection is successful and that the logical system can communicate with the intended destination.
  
  
  
  Check Authorizations:
  
  Ensure that the user has the necessary authorizations to access the RFC destination and perform the required operations.
