tax on excise

Hi guys,

We have to configure the following scenario.

Vat is to be calculated on Basic + ED ECSSECESS.

But only Basic + VAT amount is to be paid to the vendor. (EDECSSECESS) should not be paid to the vendor.

If we include ED,ECS,SECESS related condition types in the tax-code, the ED etc are also being payable to the vendor.

How to configure this scenario?

Thanks in advance
