This error typically occurs in the context of Master Data Governance (MDG) when the system is trying to access or validate data that is expected to be present in a particular logical system but cannot be found.
  Cause:
  
  Object Not Created: The object you are trying to access (e.g., a material, vendor, customer, etc.) has not been created in the specified logical system.
  Incorrect Logical System: The logical system specified may be incorrect or not properly configured in the SAP landscape.
  Data Replication Issues: There may be issues with data replication between systems, leading to the object not being available in the target logical system.

  Solution:
  
  Verify Object Existence: Check if the object (e.g., material, vendor) exists in the specified logical system. You can do this by logging into the logical system and searching for the object.
