• What is the cause and solution for SAP error message SDMI119 - Migration class is already registered ?

  The SAP error message SDMI119: Migration class is already registered typically occurs during the migration process when there is an attempt to register a migration class that has already been registered in the system. This can happen in various scenarios, such as during data migration, system upgrades, or when using specific migration tools.
  Cause:
  
  Duplicate Registration: The migration class you are trying to register is already present in the system, leading to a conflict.
