Re: PowerBI calculation problem

I’m willing to take a look, but can you please
1. create a sample file including your formulas

Re: Time Intelligence webinar- Evaluation of Year to Date Totals

It's not easy, but stick with it. Being able to ask questions definitely helps. Firstly, I don't know what formula you have for Total Sales YTD with ALL and MAX , but it is not correctly calculating YTD sales. This is the correct formula Sales YTD = CALCULATE ( [Total Sales], FILTER ( ALL &#...

Re: PQ or PP for joins??

I can’t say if you “need” these transformations, but if you do, then do them in the source system first (if possible), then PQ, then PP. Have a read of Chris Webb’s article on one ...

Re: how to multiply different columns with a dax measure [Solved]

I don't really understand, but you may find this article I wrote a couple of weeks ago useful - it seems like the principles are similar. You may be able to work it out from there.

Re: How to decide what to use?

Interesting problem. It is hard for me to give you clear advice on this despite the detail you have provided. Power Pivot is great for working over large tables of data.
