Joint Venture Cut Back-GJCB

Hi

We have a JV where we are operator.

Being Operator and we are giving services to other partners, therefore service charges are  to be charged ,and  to be shown as Expenditure in Venture 1 and 100%  to be charged from non-operator partners.

Since we are in 70:30 ratio and Service tax to be charged 100% from partner. Kindly suggest me how to do this?

Can we create New Equity Group where we can run cut back of expenditure as 100% towards non-operator partner share?

Thanks & Regards
