• What is the cause and solution for SAP error message MPE_RTG_UI074 - It is not possible to paste a node under itself ?

  The SAP error message MPE_RTG_UI074 ("It is not possible to paste a node under itself") typically occurs in the context of working with hierarchical data structures, such as when managing nodes in a tree structure (e.g., in a report or a configuration tree). This error indicates that there is an attempt to paste a node as a child of itself, which is not allowed.
  Cause:
  The error is caused by trying to perform an operation where a node is being pasted into a position that would create a circular reference. For example, if you have a node A and you try to paste it as a child of node A, it creates a situation where node A is trying to contain itself, which is logically and structurally invalid.
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check the Node Structure: Ensure that you are not trying to paste a node into itself. Review the hierarchy and confirm that the node you are trying to paste is not the same as the node you are pasting it under.
  
  
  Select the Correct Node: If you intended to paste the node under a different parent, make sure to select the correct parent node before pasting.
  
  
  Use Different Nodes: If you need to create a hierarchy, consider using different nodes that do not create a circular reference.
  
  
  Review the Operation: If you are using a script or a programmatic approach to manipulate nodes, review the logic to ensure that it does not inadvertently attempt to paste a node under itself.
  
  
  Related Information:
  
  SAP Documentation: Check the SAP Help Portal or relevant documentation for more information on managing hierarchical data structures.
  SAP Community: Engage with the SAP Community forums to see if others have encountered similar issues and what solutions they have found.
  Debugging: If you have access to debugging tools, you can trace the operation to see where the logic might be failing.
  
  If the issue persists after following these steps, consider reaching out to your SAP support team for further assistance, as they may have more specific insights based on your system configuration and version.
