• What is the cause and solution for SAP error message SMOIWS090 - RFC Logon data for system &1 not found ?

  The SAP error message SMOIWS090 indicates that the system is unable to find the RFC (Remote Function Call) logon data for a specified system. This typically occurs when there is a configuration issue related to the RFC destination in the SAP system.
  Cause:
  
  Missing RFC Destination: The RFC destination for the specified system is not defined in the SAP system.
  Incorrect Configuration: The RFC destination may be incorrectly configured, leading to the inability to find the logon data.
  Authorization Issues: The user may not have the necessary authorizations to access the RFC destination.
  System Name Mismatch: The system name specified in the error message may not match any existing RFC destination in the system.
  
  Solution:
  
  
  Check RFC Destination:
  
  Go to transaction SM59 (RFC Destinations).
  Look for the RFC destination that corresponds to the 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 by clicking on "Create" and filling in the necessary details (like target host, system number, client, user, password, etc.).
  If it exists but is misconfigured, select it and click on "Change" to update the details.
  
  
  
  Check Logon Data:
  
  Ensure that the logon data (username and password) is correct and that the user has the necessary authorizations to connect to the target system.
  
  
  
  Test Connection:
  
  After creating or updating the RFC destination, use the "Test Connection" feature in SM59 to verify that the connection works correctly.
  
  
  
  Check Authorizations:
  
  Ensure that the user account used for the RFC connection has the necessary authorizations to access the target system.
  
  
  
  Review System Name:
  
  Double-check that the system name in the error message matches the RFC destination name. If there is a discrepancy, correct it.
