A/C entries, Expenses and Accruals during sample sales invoicing

Dear Experts,

I was aware about the theoretical concept of accrual functionality in SD condition type where system posts entries to FI without debiting customer account. Day has come to implement the same practically where earlier discussions in scn by friends have not helped enough as there is no clear end of any post related to this.

Back ground of scenario;

I have configured Free of charge sample sales to deliver and then billing. Billing required because of business needs below entries;

Quality Expenses G/L: 7100012 Cr 124

Sales Basic Price: 100 Dr

Custom Duty: 10 Dr

CVD: 13.2 Dr

Cess: 0.46 Dr

HECess: 0.23 Dr

All of my condition types are accruals. System doesn't debit customer account as well as expected. However, entries are coming like below;

I have tried with all combinations in pricing procedure with account keys/accrual keys and G/Ls in VKOA but not yielding expected results.

Please suggest your expert comments.

Thanks.
