  SAP Error Message:
  
  WRF_ARTICLE_SCREENS024: The material hierarchy assignments have to start on &
  
  Cause:
  This error occurs when assigning a material to a material hierarchy node in SAP Retail, and the hierarchy node number does not start with the required character &. In SAP Retail, material hierarchy nodes must begin with an ampersand (&) to distinguish them from other nodes or categories.
  The system enforces this naming convention to ensure consistency and correct processing of material hierarchies.
  
  Explanation:
  
  Material hierarchies in SAP Retail are structured with nodes identified by unique keys.
  These keys must start with & (ampersand) to be valid.
  If you try to assign a material to a hierarchy node that does not start with &, the system throws this error.
  
  
  Solution:
  
  
  Check the Material Hierarchy Node:
  
  Verify the node number or key you are trying to assign the material to.
  Ensure it starts with the character &.
  
  
  
  Correct the Node Key:
  
  If the node does not start with &, update the node key in the material hierarchy maintenance transaction (e.g., /SAPAPO/MAT1 or relevant transaction in your system).
  Alternatively, select or create a valid node that starts with &.
  
  
  
  Reassign the Material:
  
  After correcting the node key, reassign the material to the correct hierarchy node.
  
  
  
  Check Customizing:
  
  If this is a recurring issue, check the customizing settings for material hierarchies to ensure the naming conventions are enforced and understood by users.
