• What is the cause and solution for SAP error message CMMD075 - Cannot activate the hierarchy - articles are not positioned on end nodes ?

  The SAP error message CMMD075, which states "Cannot activate the hierarchy - articles are not positioned on end nodes," typically occurs in the context of SAP's Master Data Management, particularly when dealing with product hierarchies or classification systems. This error indicates that there are articles (or products) in the hierarchy that are not correctly assigned to the end nodes of the hierarchy structure.
  Cause:
  
  Incorrect Hierarchy Structure: The hierarchy may not be properly defined, meaning that some articles are linked to nodes that are not end nodes (i.e., they are not the final level in the hierarchy).
  Missing Assignments: Articles may not be assigned to any end node, or they may be assigned to intermediate nodes instead of the final nodes.
  Data Integrity Issues: There may be inconsistencies or errors in the master data that prevent the hierarchy from being activated.
  
  Solution:
  To resolve the CMMD075 error, follow these steps:
  
  
  Check Hierarchy Structure:
  
  Review the hierarchy structure in the SAP system to ensure that it is correctly defined.
  Ensure that all articles are assigned to the appropriate end nodes.
  
  
  
  Assign Articles to End Nodes:
  
  Identify the articles that are not positioned on end nodes.
  Reassign these articles to the correct end nodes in the hierarchy.
  
  
  
  Use Transaction Codes:
  
  Use transaction codes like CM01 (for maintaining the hierarchy) or CM02 (for displaying the hierarchy) to manage and review the hierarchy structure.
  You can also use CMMT (for managing articles) to check the assignments of articles.
  
  
  
  Data Consistency Check:
  
  Perform a data consistency check to identify any discrepancies in the master data.
  Use tools or reports available in SAP to validate the hierarchy and article assignments.
  
  
  
  Re-activate the Hierarchy:
  
  After making the necessary adjustments, attempt to activate the hierarchy again.
