Is there any alternative BAPI/FM for BAPI_SALESORDER_SIMULATE to get the pricing data when we provide materials for salesorder create?

Question

Say we create sales order and provide a Material and it will give Pricing details....

Now requirement is we can use BAPI_SALESORDER_SIMULATE to provide inputs and it will return pricing data but thus takes lot of time when more materials are provided on selection screen.

So please let me know if there is any BAPI/FM?

I need an alternate logic/BAPI/FM.
