• What is the cause and solution for SAP error message UGWB014 - Recursive hierarchy structure ?

  The SAP error message UGWB014, which indicates a "Recursive hierarchy structure," typically occurs in the context of hierarchical data structures, such as organizational units, cost centers, or other master data that utilize hierarchies. This error suggests that there is a circular reference in the hierarchy, meaning that a node in the hierarchy is indirectly or directly referencing itself, which is not allowed.
  Cause:
  
  Circular Reference: The most common cause of this error is that a node in the hierarchy is set up in such a way that it points back to itself, either directly or through a chain of other nodes.
  Incorrect Hierarchy Configuration: The hierarchy may have been incorrectly configured, leading to a situation where the parent-child relationships are not valid.
  Data Entry Errors: Manual data entry errors can lead to incorrect relationships being established between nodes.
  
  Solution:
  
  Review Hierarchy Structure: Check the hierarchy structure for any circular references. This can often be done through the relevant transaction codes in SAP (e.g., OKEQ for cost center hierarchies).
  Correct Relationships: Identify and correct any incorrect parent-child relationships. Ensure that no node is pointing back to itself or creating a loop.
  Use Hierarchy Maintenance Tools: Utilize SAP's hierarchy maintenance tools to visualize and manage the hierarchy. This can help in identifying problematic areas.
  Data Validation: Implement data validation checks to prevent the creation of circular references in the future.
  Consult Documentation: Refer to SAP documentation or help resources for specific guidance on managing hierarchies in your version of SAP.

  Testing: After making changes, test the hierarchy to ensure that the error is resolved and that the hierarchy functions as expected.
