Clearing of Advance to vendor?

Hello,

I need to know that we give our vendors an advance payment for expenses to incur on our behalf. I record that advance via F-43 with the Special GL Indicator. After few weeks they send us the invoices(expensews details). I record those through fb60. How can i clear this as it is increasing the balance of Advance and payable also. Kindly advise a way to adjust the advance to vendor.

Regards,

Safi
