  The SAP error message MDG_DT_UI017 indicates that there is an attempt to add an entity that has already been included in a hierarchy for another entity. This typically occurs in the context of Master Data Governance (MDG) when managing hierarchies of master data entities.
  Cause:
  The error is triggered when:
  
  You are trying to add a child entity to a parent entity in a hierarchy, but the child entity is already associated with another parent entity in the same hierarchy.
  The system enforces a rule that prevents an entity from being part of multiple parent entities in the same hierarchy.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Existing Hierarchies:
  
  Review the existing hierarchies to see where the entity is already assigned. You can do this by navigating to the relevant hierarchy management transaction or application in SAP MDG.
  
  
  
  Remove from Previous Parent:
  
  If the entity needs to be moved to a new parent, you will need to first remove it from its current parent entity in the hierarchy before adding it to the new parent.
  
  
  
  Modify Hierarchy Structure:
  
  If the business requirement allows, consider restructuring the hierarchy to accommodate the changes without violating the rules.
  
  
  
  Consult Documentation:
  
  Refer to the SAP documentation or help resources for specific guidelines on managing hierarchies in MDG.
  
  
  
  Check for Custom Logic:
