Freight Amount Exemption in Tax Calculations

Hi Gurus,

  Currently in my system tax is calculated based on total net value in SAP CRM. Our requirement is to exclude freight amount in this tax calculation. We tried following the instructions specified in SAP note 942308. But due to very limited knowledge in Java, not able to achieve the requirement.

I hope someone of this group have encountered this issue in SAP CRM. Appreciate, if someone could provide sample JAVA code.

Trying to find out, what below method setObjectForUserExits are doing? How vertex knows FreightAmount. How to know, this is tax exempt?

prItem.setObjectForUserExits("GrossAmount", prItem.getSubtotal

(PricingCustomizingConstants.ConditionSubtotal.SUBTOTAL_5).getValue()); // converts to BigDecimal

from ICurrencyValue

prItem.setObjectForUserExits("FreightAmount", prItem.getSubtotal

(PricingCustomizingConstants.ConditionSubtotal.SUBTOTAL_4).getValue()); // converts to BigDecimal

from ICurrencyValue

prItem.setObjectForUserExits("CustomerAccountClass","Y         "); What is this CustomerAccountClass and what is the spaces mean?

Regards,

Bhanu
