• What is the cause and solution for SAP error message KU155 - Hierarchy is not complete ?

  The SAP error message KU155, which states "Hierarchy is not complete," typically occurs in the context of SAP Controlling (CO) when working with cost center hierarchies or other hierarchical structures. This error indicates that the hierarchy you are trying to use is not fully defined or is missing certain elements that are required for it to function correctly.
  Causes of Error KU155
  
  
  Incomplete Hierarchy Definition: The hierarchy may not have all the necessary nodes or levels defined. For example, if a parent node is missing child nodes that are required for the hierarchy to be complete.
  
  
  Inactive Nodes: Some nodes in the hierarchy may be inactive or not properly configured, which can lead to the hierarchy being considered incomplete.
  
  
  Missing Assignments: There may be missing assignments between nodes, such as a cost center not being assigned to the correct hierarchy level.
  
  
  Data Consistency Issues: There could be inconsistencies in the data that prevent the hierarchy from being recognized as complete.
  
  
  Solutions to Error KU155
  
  
  Check Hierarchy Structure: Review the hierarchy structure in the SAP system. Ensure that all necessary nodes are defined and that there are no missing links between parent and child nodes.
  
  
  Activate Inactive Nodes: If there are any inactive nodes in the hierarchy, consider activating them or removing them if they are not needed.
  
  
  Review Assignments: Verify that all cost centers or other relevant objects are correctly assigned to the hierarchy. Make sure that each node has the appropriate child nodes.
  
  
  Use Transaction Codes: Utilize transaction codes such as KSH1 (Create Cost Center Hierarchy) or KSH2 (Change Cost Center Hierarchy) to review and modify the hierarchy as needed.
  
  
  Consistency Check: Perform a consistency check on the hierarchy to identify any issues. This can often be done through specific reports or tools within SAP.
  
  
  Consult Documentation: Refer to SAP documentation or help resources for specific guidelines on setting up and maintaining hierarchies in your version of SAP.
  
  
  Related Information
  
  
  Transaction Codes: Familiarize yourself with relevant transaction codes for managing hierarchies, such as KSH1, KSH2, KSH3 (Display Cost Center Hierarchy), and others related to your specific module.
  
  
  SAP Notes: Check SAP Notes for any known issues or patches related to hierarchy management that may address the error.
  
  
  User Roles and Authorizations: Ensure that you have the necessary authorizations to view and modify the hierarchy. Lack of permissions can sometimes lead to incomplete views of the hierarchy.
  
  
  Testing Changes: After making changes to the hierarchy, test the functionality to ensure that the error does not reoccur.
