  Ensure that the item category you are trying to use is correctly defined and not reserved for system use.
  
  
  
  Use a Different Item Category:
  
  If the item category you are trying to use is indeed reserved, consider using a different item category that is allowed for your transaction.
  
  
  
  Review Transaction Type Settings:
  
  Check the settings for the transaction type you are using to see if there are any restrictions on item categories.
