  SAP Error Message:
  WRF_ARTICLE_SCREENS027
  
  Text: Because of "Mandatory Assignment", at least 1 assignment has to end on &
  
  Cause:
  This error occurs in SAP Retail (usually in the Article Master or related screens) when you have defined a "Mandatory Assignment" for an article or article hierarchy, but the system detects that there is no valid assignment ending on the required organizational unit (such as a sales organization, distribution channel, or other organizational level).
  In other words, the system expects that at least one assignment (e.g., article assignment to a sales org, store, or assortment) must be completed and valid for the article, but it finds none. The "&" in the message is a placeholder for the organizational unit or level where the assignment must end.
  
  Explanation:
  
  Mandatory Assignment means that the article must be assigned to at least one organizational unit (like a sales org, store, or assortment) to be valid.
  The system checks the article assignments during save or validation.
  If no assignment is found that meets the mandatory criteria, the system throws this error.
  This is a data consistency and business rule enforcement to ensure articles are properly assigned for sales, inventory, or reporting purposes.
  
  
  Solution:
  
  
  Check Article Assignments:
  
  Go to the article master data maintenance transaction (e.g., MM43, WRF_ARTICLE or relevant transaction in your system).
  Verify the assignments of the article to organizational units such as sales organizations, distribution channels, stores, or assortments.
  Ensure that at least one assignment exists and is complete.
  
  
  
  Create or Correct Assignments:
  
  If no assignment exists, create a valid assignment for the article to the required organizational unit.
  If an assignment exists but is incomplete or incorrect, correct it so that it ends on the required organizational unit.
  
  
  
  Check Configuration:
  
  Review the configuration for mandatory assignments in IMG under Retail ? Master Data ? Article ? Assignments.
  Confirm which organizational units are set as mandatory for article assignments.
  Adjust the configuration if necessary (e.g., if the mandatory assignment rule is too strict or incorrectly set).
  
  
  
  Data Consistency Check:
  
  Run consistency checks or reports to identify articles missing mandatory assignments.
  Fix the data accordingly.
  
  
  
  
  Related Information:
  
  This error is common in SAP Retail environments where article assignments are critical for sales, pricing, and inventory management.
  The error message may appear during article creation, change, or during batch jobs that validate article data.
  The "&" in the message is a variable and will be replaced by the actual organizational unit or level in your system.
  If you have custom developments or enhancements related to article assignments, verify that they comply with mandatory assignment rules.
  Consult SAP Notes or Retail documentation for specific details on article assignment rules.
