This error typically occurs in the context of SAP Landscape Transformation (SLT) or when using the SAP Data Services for data replication.

  Solution:
  
  Verify Database Systems: Ensure that the source and target database systems are correctly configured and that they match the expected types. Check the database type in the SLT configuration or the data replication settings.
  Check Configuration Settings: Review the configuration settings in the SLT or data replication setup. Make sure that the source and target connections are correctly defined and that the database types are compatible.
  Update or Reconfigure: If there is a mismatch, you may need to update the configuration to point to the correct database system. This may involve reconfiguring the SLT or data replication settings.
  Consult Documentation: Refer to the SAP documentation for the specific version of the tools you are using. There may be additional steps or considerations based on the version or specific setup.
