JoinedDatasource - How to use joinedDatasource with Customer, SalesArrangement and PriceSpecification.PropertyValuation

Hi all

I've tried to create JoinedDatasource by using Customer , SalesArrangement and PriceSpecification.PropertyValuation.

But I'm not able to select the key for joining between  SalesArrangement and PriceSpecification.PropertyValuation.

I've used

SalesArrangement.CustomerGroupCode = PriceSpecification.PropertyValuation.PriceSpecificationElementPropertyValuation/PriceSpecificationElementPropertyValueCode

But it's not work.

what I  want is  to view price list with specific customer group.

If you know the the better way. please let me know.

Best Regards,

Krit R.
