Sales order simulation bapi and material price group???

Hello every one...

I am calling BAPI_SALESORDER_SIMULATE to get the pricing simulation of a sales order, My requirement is that I want to enter Material Pricing group (KONDM) so that pricing be simulated according to the material pricing group I enter..... but the simulation bapi does not provide this field,,, I cannot use sales order create from data2 bapi,, as it does not provide condition table as output, which is also my core requirement,,, my question is that is there some bapi/fm where I can provide material pricing group along with other info and retrieve complete simulation of sales order pricing with condition details aswell....

thanks
