  Certainly! Here's a detailed explanation for the SAP error message:
  
  SAP Error Message:
  WRF_ARTICLE_SCREENS001: Each fiber code can only be used once
  
  Cause:
  This error typically occurs in SAP systems (often in industry-specific solutions like SAP Apparel and Footwear, or custom developments related to material master or article management) when you try to assign the same fiber code multiple times to a single article or material where the business logic requires each fiber code to be unique per article.
  
  Fiber code here refers to a classification or characteristic code representing a fiber type or material component.
  The system enforces a rule that each fiber code can only be assigned once per article to avoid duplication or inconsistent data.
  The error is triggered during data entry, upload, or processing when the same fiber code appears more than once for the same article.
  
  
  Solution:
  To resolve this error, you should:
  
  
  Check the fiber codes assigned to the article:
  
  Review the article master data or the relevant data screen where fiber codes are maintained.
  Identify if the same fiber code is listed multiple times.
  
  
  
  Remove duplicate fiber codes:
  
  Ensure that each fiber code is unique for the article.
  Delete or correct any duplicate entries.
  
  
  
  Validate data upload files (if applicable):
  
  If the error occurs during a batch upload or data migration, check the source file for duplicate fiber codes for the same article.
  Correct the file before re-uploading.
  
  
  
  Check custom validations or user exits:
  
  If this is a custom error message (WRF prefix suggests a custom or industry-specific message), review the custom code or validation logic enforcing this rule.
  Adjust the logic if the business requirement has changed.

  SAP Notes:  
  
  Since this is likely a custom message, no standard SAP Note may exist, but check your system's message repository or consult your SAP support team.
  
  
  Best Practice:  
  
  Maintain clean and consistent master data.
  Implement validations at data entry points to prevent duplicates.
  Document fiber codes and their usage rules clearly for end users.
