  SAP Error Message:
  WRF_ARTICLE_SCREENS028
  
  Text: At least one article hierarchy assignment must have the correct validity.
  
  Cause:
  This error occurs when you try to save or process an article (material) in SAP Retail, but the system does not find any valid article hierarchy assignment for the article within the specified validity period. In SAP Retail, articles must be assigned to at least one article hierarchy node with a validity period that covers the current date or the date of the transaction.
  In other words:  
  
  The article is missing an assignment to an article hierarchy node, or  
  The existing assignment(s) have validity dates that do not include the current date or the relevant date for the operation.
  
  
  Explanation:
  
  Article Hierarchy: A structured classification of articles used for reporting, pricing, assortment planning, and other retail processes.
  Validity Period: Each assignment of an article to a hierarchy node has a start and end date. The system checks if the assignment is valid on the date of the transaction or the current date.
  If no valid assignment exists, the system cannot correctly classify the article, leading to this error.
  
  
  Solution:
  
  
  Check Article Hierarchy Assignments:
  
  Go to the article master data maintenance transaction (e.g., MM42 or the relevant retail article maintenance transaction).
  Navigate to the Article Hierarchy assignment tab.
  Verify if the article is assigned to at least one hierarchy node.
  
  
  
  Check Validity Dates:
  
  Ensure that the validity period (start and end dates) of the article hierarchy assignment covers the current date or the date relevant to your transaction.
  If the validity period is expired or not yet started, adjust the dates accordingly.
  
  
  
  Create or Correct Assignments:
  
  If no assignment exists, create a new assignment to the appropriate article hierarchy node.
  If the assignment exists but is invalid, update the validity dates.
  
  
  
  Save and Reprocess:
  
  After correcting the assignments and validity, save the article master data.
  Retry the operation that caused the error.
  
  
  
  
  Additional Information:
  
  This error is common during article creation, update, or when running processes that depend on article classification (e.g., pricing, assortment planning, promotions).
  Article hierarchy assignments are crucial for retail processes and reporting.
  Always ensure that the article hierarchy structure is maintained properly and that articles are assigned correctly.
  If you are unsure about which hierarchy node to assign, consult your retail master data team or hierarchy management team.
