• What is the cause and solution for SAP error message WRF_ARTICLE_SCREENS009 - The hierarchy is not valid ?

  SAP Error Message:
  
  WRF_ARTICLE_SCREENS009 The hierarchy is not valid
  
  Cause:
  This error typically occurs in SAP Retail (specifically in Article Master or Assortment Management scenarios) when the product hierarchy assigned to an article or assortment is not valid or inconsistent. The hierarchy might be incomplete, incorrectly maintained, or the article is assigned to a hierarchy node that does not exist or is inactive.
  Common causes include:  
  
  The product hierarchy node assigned to the article or assortment is missing or deleted.  
  The hierarchy node is not active or valid for the current organizational context.  
  The hierarchy structure is incomplete or has inconsistencies (e.g., missing parent nodes).  
  Incorrect or incomplete hierarchy assignment during article creation or maintenance.  
  Data inconsistencies due to transport or master data upload errors.
  
  
  Solution:
  
  
  Check Product Hierarchy Maintenance:  
  
  Go to transaction /n/SCWM/MAT1 or the relevant product hierarchy maintenance transaction (e.g., MMH1 for hierarchy maintenance).  
  Verify that the hierarchy node assigned to the article exists and is active.  
  Ensure the hierarchy is complete and correctly structured.
  
  
  
  Validate Article Assignment:  
  
  Check the article master data (transaction MM03 or relevant retail article master transaction) to confirm the product hierarchy node assigned is correct.  
  If incorrect, assign the correct and valid hierarchy node.
  
  
  
  Hierarchy Consistency Check:  
  
  Run consistency checks or reports to identify hierarchy inconsistencies.  
  Use SAP standard reports or tools like RRMHIERCHK (if available) to check hierarchy validity.
  
  
  
  Reassign or Correct Hierarchy:  
  
  If the hierarchy node is inactive or deleted, either reactivate it or assign a valid node to the article.  
  If the hierarchy is incomplete, complete the missing nodes or correct the structure.
  
  
  
  Transport and Data Upload Checks:  
  
  If the error appeared after a transport or data upload, verify that the hierarchy data was correctly transported or uploaded.  
  Re-import or correct the hierarchy data if necessary.
