This is not a problem it is the nature of the table definitions and the 
query. The PK is "ZTBR_TransactionCode", but you are joining on 
fact."Account_Number"=bracs_map."GCoA"ANDfact."Expense_Type"=bracs_map."EXPENSE 
FLAG". Since you indicate that there are multiple account numbers in the 
table then it is no surprise that the "ZTBR_TransactionCode" is repeated.
