  Cause:
  
  The message indicates that the material (product) with the given material number (&1) already exists in the promotion or sales document, but the quantity has been changed/modified.
  This usually happens when:
  
  You try to add a promotional material to a sales document or promotion condition that is already present.
  The system detects a duplicate entry for the same material but with a different quantity.
  The system is informing you that instead of adding a new line, the quantity of the existing material line has been updated.
  
  
  
  
  Explanation:
  
  In promotion processing, materials are often added automatically or manually.
  To avoid duplicate lines for the same material, SAP merges the entries and updates the quantity.
  The message is informational, indicating that the system has adjusted the quantity rather than creating a duplicate line.
  
  
  Solution:
  
  Review the sales document or promotion condition to confirm that the material is already present.
  If you intended to add the material again, check if the quantity modification is correct.
  No error correction is usually needed because this message is informational.
  If you want to add the material as a separate line (which is generally not recommended), you may need to adjust the logic or settings in the promotion or sales document processing.
  If this message is causing issues in custom developments or user exits, review the code to handle this message properly (e.g., treat it as informational rather than an error).
