USE tax calculation

Hi,

I created a PO with amount of 1000$ and do the PO receipt for whole amount.

After PO receipt my 4310 DMAAI is getting debited by amount 1000$ and at the same time 4320 us getting credited with amount 1000$.

I am using USE tax (Tax explanation code U with tax percentage of 10). So DMAAI 4350 debited with amount 100$ and 4355  credited with amount 100$.

After doing the voucher match, 4320 DMAAI is getting debited with amount 1000$ and 4355 DMAAI debited with amount 100$.

at the same time PC AAI credited with amount 1000$ and PT AAI  credited with amount 100$

Below are my query

1. How to proceed to do payment for both the supplier and tax authority(how to segregate both amount).
