• What is the cause and solution for SAP error message WZ108 - RFC destination '&1' exists already, migration scheduled ?

  SAP Error Message:
  
  WZ108 RFC destination '&1' exists already, migration scheduled
  
  Meaning / Cause
  This warning message indicates that an RFC destination with the specified name (&1 is a placeholder for the actual destination name) already exists in the SAP system. Additionally, a migration or update process related to this RFC destination has been scheduled or is in progress.
  This situation typically arises during system upgrades, client copies, or when configuring RFC destinations where the system detects that the destination is already present and a migration (e.g., transport or upgrade-related migration) is planned or underway to update the destination's configuration or attributes.
  
  When does it occur?
  
  During system upgrade or patching activities involving RFC destinations.
  When importing transports that contain RFC destination definitions.
  When creating or modifying RFC destinations that have been flagged for migration.
  During client copy or system copy procedures where RFC destinations are migrated or adjusted.
  
  
  Solution / How to resolve
  
  
  Check the existing RFC destination:
  
  Go to transaction SM59.
  Look for the RFC destination mentioned in the message.
  Verify its configuration and status.
  
  
  
  Check migration status:
  
  The system might have scheduled a migration task to update or replace the RFC destination.
  Check if there are any background jobs or transport requests related to this migration.
  Use transaction SM37 to look for jobs related to migration or RFC destination updates.
  
  
  
  Wait for migration to complete:
  
  If a migration job is scheduled or running, wait for it to complete.
  After completion, verify if the RFC destination is updated correctly.
  
  
  
  If migration is stuck or failed:
  
  Investigate the cause of failure in the job logs.
  Re-run or manually perform the migration steps if necessary.
  Consult SAP Notes or OSS messages related to the migration process.
  
  
  
  Avoid duplicate creation:
  
  Do not create a new RFC destination with the same name while migration is pending.
  If you need to create a new destination, use a different name.
  
  
  
  Check SAP Notes:
