How does RV45A-ENDBK (Total Amount) React in pricing?

Sample . Service Fee = 560 using a service material number

It must react in Net as = 500

Tax = 60

The acounting entry will be

Customer AR 560

Tax Adjustment 60

Equity 500

Service Income 500

Tax Payable 60

Customer AR 560

The RV45A-ENDBK (Total Amount) always react as Zero). What should i do if I need to show still 560 in the total amount header data? How does both Customer AR be in debit and credit.

I can get Tax=60

Tax Adjustment 60

Equity 500

Service Income 500

Tax Payable 60
