Updating item master through query

Hi All,

Can we use query to directly update the OITM table. Is there any other table that i need to take note and synz back the data inconsistency? We cannot use the SAP to update back the item because the item already having stock quantity/transaction.

UPDATE OITM  SET InvntItem ='N', SellItem = 'Y', PrchseItem = 'N', IssueMthd = 'B', ManBtchNum = 'N', ManSerNum = 'N' WHERE ItemCode = 'XXXX'
