• What is the cause and solution for SAP error message K0130 - Node & is used in itself. ?

  The SAP error message K0130, which states "Node & is used in itself," typically occurs in the context of the SAP Controlling (CO) module, particularly when dealing with cost center hierarchies or other organizational structures. This error indicates that there is a circular reference in the hierarchy where a node (such as a cost center or internal order) is incorrectly defined to include itself as a subordinate.
  Cause:
  The primary cause of this error is a misconfiguration in the hierarchy structure. Specifically, it happens when:
  
  A node is defined in such a way that it references itself directly or indirectly.
  There is a mistake in the assignment of nodes in the hierarchy, leading to a loop.
  
  Solution:
  To resolve the K0130 error, you can follow these steps:
  
  
  Check the Hierarchy Structure:
  
  Navigate to the relevant hierarchy in the SAP system (e.g., cost center hierarchy).
  Review the nodes and their relationships to ensure that no node is referencing itself.
  
  
  
  Correct the Node Assignment:
  
  If you find a node that is incorrectly assigned to itself, modify the assignment to remove the self-reference.
  Ensure that the hierarchy is structured correctly without any circular references.
  
  
  
  Use Transaction Codes:
  
  You can use transaction codes like KSH1 (Create Cost Center) or KSH2 (Change Cost Center) to review and modify the cost center hierarchy.
  For internal orders, you might use KO01 (Create Internal Order) or KO02 (Change Internal Order).
  
  
  
  Validate Changes:
  
  After making the necessary changes, validate the hierarchy to ensure that the error is resolved.
  You can do this by attempting to save or activate the hierarchy again.
  
  
  
  Consult Documentation:
  
  If you are unsure about the hierarchy structure, refer to SAP documentation or consult with a colleague who has experience in configuring the CO module.
