• What is the cause and solution for SAP error message FDT_CORE761 - Node ID &1 (&2) cannot be moved underneath itself (recursion) ?

  The SAP error message FDT_CORE761 indicates that there is an attempt to move a node in a hierarchical structure (like a tree) to a position that would create a recursive relationship. In simpler terms, it means that you are trying to place a node under itself, which is not allowed because it would create an infinite loop.
  Cause:
  
  Hierarchical Structure Violation: The most common cause of this error is that the system is trying to move a node to a parent position that is already one of its descendants. This creates a circular reference.
  Incorrect Logic in Custom Code: If there is custom logic or a program that manipulates the hierarchy, it may inadvertently attempt to create this recursive relationship.
  User Error: A user may be trying to manually reorganize nodes in a way that violates the hierarchy rules.
  
  Solution:
  
  Check Node Relationships: Review the current hierarchy of nodes to ensure that the node you are trying to move does not already exist in the path to the target parent node.
  Use the Correct Move Functionality: Ensure that you are using the correct functionality or transaction to move nodes. If you are using a custom program, verify the logic to ensure it does not allow moving a node under itself.
  Debug Custom Code: If the error arises from custom code, debug the logic to ensure that it checks for existing parent-child relationships before attempting to move nodes.
  Consult Documentation: Refer to SAP documentation or help resources for guidelines on managing hierarchical structures to avoid such errors.
  
  Related Information:
  
  SAP Notes: Check SAP Notes for any known issues or patches related to this error message.
  Transaction Codes: Familiarize yourself with relevant transaction codes that deal with hierarchical structures, such as those used for managing master data or organizational structures.
  User Training: If this error is frequently encountered by users, consider providing training on how to properly manage node relationships within the system.
  
  By following these steps, you should be able to resolve the FDT_CORE761 error and prevent it from occurring in the future.
