About Ledger Accruals in Ax 2012

Hi, I tried to perform a ledger accrual transaction (Prepaid Insurance) in Ax 2012. But I'm not sure if I have done it right or not.

In the Ledger Accrual scheme, I chose:

Insurance Expense account -> Debit

Prepaid Insurance account -> Credit

In the Journal line, I entered the account Prepaid Insurance. I then went to Functions -> Ledger Accruals. Entered the offset account (Bank) and posted the line.

When I checked in the Inquiries-> Voucher, this is what showed:

Insurance Expense  account 1200   Debit

Bank account                            1200   Credit

I then clicked on Transaction origin, and the transactions were as displayed below:

Bank account                                 -1200

Insurance account                          1200

Bank                                                  -1200

Prepaid Insurance                           133.33

Insurance Expense                         -133.33

Prepaid Insurance                            133.33

Insurance Expense                          -133.33

.

.

so on till end of the year (Total 9 transactions, from April to December)

Here, I thought the Prepaid Insurance would be credited each month and Insurance Expense debited. But, it's happening the other way around.

Can someone please help me understand this? Thanks in advance.
