How to post security deposit payment to customer

Dear Sir,

I know that we use F-29 when customer give us advance payment. What T code we should use when we pay a security deposit to our customer?

Currently we post direct entry in our GL i.e, security deposit Debit and Bank credit through F-02. No amount is reflected in customer account.

Please guide me how I can post payment to my customer against refundable security deposit.

Thanks

Bilal
