After I reviewed all transactions in both QB and Oracle.
I found the error transaction in QB JE#449 Dr. 50002 Cr. 230015 Amt. 1,467.22.
The original transaction is in Mar-15 then this transaction has been changed the date and recorded again in Apr-15.
(The transaction in Mar has been removed due to in QB can change everything. it doesn't have period closing function)
So the result is this transaction has been double uploaded in SharePoint both Mar and Apr.
However the final balance as of Sep-15 is not variance due to Sato has already created the TR# 565 to correct the double transaction.
