  Client-Specific Settings: Check if there are any client-specific settings or data that need to be adjusted. This may involve reviewing client-specific configurations in the Integration Directory.
  Re-transport Mapping: If the mapping was transported, consider re-transporting it to ensure that all necessary components are included and correctly configured.
  Check Authorizations: Ensure that the user executing the mapping has the necessary authorizations to access the mapping and related objects. You may need to consult with your security team to verify this.
  Debugging: If the issue persists, consider enabling debugging for the mapping process to get more detailed information about where the error is occurring.
