query result different with profit and loss statement

Hi all,

I run query Sum(JDT1.Debit - JDT1.Credit), and then compare the query result with the profit and loss statement, and there is different.

The difference is about 0.01.

At SAP, the Decimal places is set to 2.

I already checked the data, and their amount in 2 decimal.

Do anyone know such problem and what kind of query must I use so the result can be compared with the profit and loss statement ?

Thx.
