  SAP Error Message WX471
  Message Text:
  
  Please delete supplying plant(s) for material group & first
  
  Cause
  This error occurs when you try to delete or change a material group in SAP, but there are still one or more supplying plants assigned to that material group. SAP enforces data consistency, so you cannot delete a material group if it is still linked to supplying plants.
  In other words, the system prevents deletion of the material group because it is still referenced by one or more supplying plants. The "&" in the message is a placeholder for the material group code.
  
  Explanation
  
  Material Group: A classification of materials used for grouping similar materials.
  Supplying Plant: A plant that supplies materials belonging to a particular material group.
  The system maintains relationships between material groups and supplying plants.
  Before deleting a material group, all supplying plants assigned to it must be removed.
  
  
  Solution
  
  
  Identify Supplying Plants Assigned to the Material Group:
  
  Use transaction codes like MM03 (Display Material) or SPRO to check the material group assignments.
  Alternatively, use table T460A (Material Group) and related tables like T001W (Plants) or custom tables if applicable.
  
  
  
  Delete or Reassign Supplying Plants:
  
  Navigate to the configuration or master data where supplying plants are assigned to the material group.
  Remove the supplying plant assignments for the material group you want to delete.
  If the supplying plants are still needed, reassign them to a different material group.
  
  
  
  Delete the Material Group:
  
  After all supplying plants have been deleted or reassigned, proceed to delete the material group.
  Use transaction OMS2 (Material Groups) or the relevant customizing transaction.
  
  
  
  Check for Dependencies:
  
  Ensure no other dependencies exist (e.g., materials assigned to the group).
  If materials are assigned, you may need to reassign or delete those materials first.
