Anybody to use 'PIQ_CALCULATE' instead of 'PRICING' FM to get invoice price.

We are suffering from low performance of price simulation with 'PRICING' FM.

Actually the performance is not bad but we have so many combinations of customers-materials.

So if we can have any chance to make it better as performance, we would like to use it 'PIQ_CALCULATE' which is optimized FM to send price information.

We are not accustomed to it and can not find enough information cause the FM is only in S/4 HANA.

Can we have any guide about how to use?
