Chart of account (ledger account) balance not accurate

Hello friend,

chart of accounts balance is not accurate it is showing *3 balance.I found this problem in chart of accounts where account type is TOTAL.

for e.g. A is total account and B,C are profit and loss account so A must show the total of B and C.means if B+C=10 then A is also 10.

but in my case B and C are having no problem but A is showing balance as 30

kindly help.

how do system re-calculate balances in ax 2009.
