• What is the cause and solution for SAP error message WRF_PRC_CUST026 - The hierarchy level must be unique for each tree type ?

  The SAP error message WRF_PRC_CUST026 indicates that there is an issue with the hierarchy levels in the pricing or master data configuration. Specifically, it means that the hierarchy level you are trying to create or modify is not unique for the specified tree type. This can occur in various contexts, such as when dealing with pricing conditions, product hierarchies, or other hierarchical structures in SAP.
  Cause:
  
  Duplicate Hierarchy Levels: The hierarchy level you are trying to assign already exists for the same tree type. Each tree type must have unique hierarchy levels to avoid conflicts.
  Incorrect Configuration: There may be a misconfiguration in the settings for the hierarchy levels or tree types in the system.
  Data Entry Errors: Manual data entry errors can lead to duplicate entries or incorrect hierarchy levels being assigned.
  
  Solution:
  
  
  Check Existing Hierarchy Levels:
  
  Navigate to the relevant transaction (e.g., SPRO for configuration) and check the existing hierarchy levels for the tree type in question.
  Ensure that the hierarchy level you are trying to create does not already exist.
  
  
  
  Modify or Delete Duplicates:
  
  If you find that the hierarchy level already exists, you may need to modify or delete the duplicate entry to maintain uniqueness.
  Ensure that any changes made do not affect other configurations or data that rely on the hierarchy.
  
  
  
  Review Configuration Settings:
  
  Go to the configuration settings for the relevant module (e.g., Sales and Distribution, Material Management) and verify that the hierarchy levels and tree types are set up correctly.
  Make sure that the tree types are defined properly and that their hierarchy levels are unique.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or help resources for guidance on setting up hierarchy levels and tree types correctly.
  
  
  
  Testing:
  
  After making changes, test the configuration to ensure that the error does not reoccur and that the system behaves as expected.
  
  
  
  Related Information:
  
  Transaction Codes: You may need to use transaction codes like SPRO (Customizing), SE11 (Data Dictionary), or SE16 (Data Browser) to investigate the hierarchy levels and tree types.
  SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide additional guidance on hierarchy configurations.
  User Roles and Authorizations: Ensure that you have the necessary permissions to make changes to the hierarchy levels and configurations.
  
  If the issue persists after following these steps, it may be beneficial to consult with an SAP expert or your organization's SAP support team for further assistance.
