how to handle deduction tax when creating voucher

 Dear everyone,

Currently, our user want to to use a deduction tax rate in order to deduct on labor charges when they create voucher.

Normally, for voucher which has normal tax rate, its accounting entry would like below,

DR:

TEST   100

TAX     5

AR:

Account Payable 105

However, for the deduction tax which user intend to use, the voucher accounting entry would like below,

DR:

TEST 100

AR:

Account Payable 95

Deduction Tax 5

The accounting entry is a little like India withholding accounting entry.

Could you please help me or give any idea on how to achieve this target in PeopleSoft?

Many thanks in advance!
