Security deposit payment

Hi,

My requirement is to account the payments to a security deposit separately till the time it is not released.

Details as below.

1. When the security deposit is cleared by a payment, the payment item should reflect in G/L account X001.

2. When the security deposit is released, the payment amount should go to G/L X002 debitting the account X001 by the equivalent amount.

Step 1 can be achieved through the config of EK01, however can anyone please suggest if there is something which helps to achieve step 2? That means when a security deposit is released it should be transferred to another G/L account?

Thanks a lot in advance.
