  The SAP error message WW108, which states "Material group not deleted," typically occurs when there is an attempt to delete a material group that is still in use or has dependencies in the system. Here are the common causes, solutions, and related information for this error:
  Causes:
  
  Active Materials: The material group you are trying to delete is still assigned to one or more materials in the system.
  Dependencies: There may be other dependencies, such as open purchase orders, sales orders, or stock items that reference the material group.
  Authorizations: The user may not have the necessary authorizations to delete the material group.
  Configuration Settings: Certain configuration settings in the system may prevent the deletion of material groups that are still in use.
  
  Solutions:
  
  
  Check Material Assignments:
  
  Use transaction code MM03 to check if any materials are still assigned to the material group you want to delete. If there are materials, you will need to reassign them to a different material group or delete them if they are no longer needed.
  
  
  
  Review Dependencies:
  
  Check for any open transactions (like purchase orders, sales orders, or stock movements) that might be using the material group. You can use transaction codes like ME2N (for purchase orders) or VA03 (for sales orders) to find related documents.
  
  
  
  Change Material Group:
  
  If there are materials assigned to the group, consider changing their material group to another valid group using transaction code MM02.
  
  
  
  Authorization Check:
  
  Ensure that the user attempting to delete the material group has the necessary authorizations. This can be checked with your SAP security team.
  
  
  
  System Configuration:
  
  Consult with your SAP Basis or configuration team to ensure that there are no system settings preventing the deletion of the material group.
  
  
  
  Use Transaction Code MM06:
  
  If you want to mark the material group for deletion instead of deleting it outright, you can use transaction code MM06. This will allow you to mark the group as inactive without deleting it.
