I know, I’m back again at validations, but this time is a bit different. Recently I’ve found myselft in a project where the data that was coming in was not fulfilling the sepcified requirements. We tend to thing that data that comes out of a system will always be pristine, but well, at least in one instance it was not. There were some validations set in place in Access + VBA. But then, even if the access was set out to execute every day you have to go in, check the output, and each file had it’s own validation access. Well, not great. Since the patience was running thin (errors kept apprearing in different places) it was decided that a full validatino check was to be set out. Or at least something much deeper than we had now. I figured out that we might be able to build something in Power BI. Data Validation with Power BI. Odd? yes, but hey, you gotta do what you gotta do.

Calculation Groups biggest contribution is to help us reduce the number of measures that we have to create and manage. However, sometimes, me might want measures again… Of course we can forgo the calc group altogether, but we might want to keep the centralized logic while having actual measures, and not measures + a filter as we usually do with calculation groups. The most relevant use case that comes to mind is when we do not want our calculation items to travel to the tooltip or drill through pages, as I discussed in this post not long ago. I guess that for most use cases, creating the measures manually is not the end of the world, but hey, scripting is fun and is cool, so let’s automate that a bit.

It’s a terrible title, but by the end I hope it makes sense

Today I had some spare time and I thought I would do some c# that is always good to keep your mind going.  The goal was to create a script that given a base measure, you can then specify a column and a new measure will be generated for each diferent value of the column, in a pattern like CALCULATE([Base Measure], tbl[Column] = Value1 ) and the same for value2, 3 etc of that same column.

Hello there, today I don’t have any new fancy use case for calculation groups or anything else, but rather a repository of links to the best of the best c# scripts… to create calculation groups. The main use of this post is to point people this way when I do a presentation on calculation groups, for example. Since they are «one-click» means you can just store it as Macro/Quick Action and even put it in a custom toolbar if you are using Tabular Editor 3 (which you should!). I’ll just start with two, but I plan adding more over time.

This post is based in a true use case. The customer followed the market share trends, to see how it compared to the rest, as a manufacturer, and at a brand level.

So far so good. But coming from excel they were used to build charts any way they saw fit, so they liked to see on the same chart their own year-on-year growth in general as a manufacturer, then in different distribution channels, then specifically the growth of their two main brands, and then the growth on different regions. That alone was my first challenge. But then they said that that they would like to know how others were doing on the tooltip. But of course, when looking at a manufacturer-level value, they would like to see their value together with that for other manufacturers, and when looking at a brand level then wanted to see it with all  the other brands. I added to the mix that it would be nice to see highlighted their own value in the tooltip of course.

Ok, by now you probably know I’m a liiiiitle too much into calculation groups. Once you try calculation groups there’s no going back. Particularly if you do time intelligence analysis (that is comparing values with the previous year, but many other things as well). The reason is that normally you would create a new measure for each pair of calculation – measure, (e.g. Sales Amout PY, Sales Amount YTD,  Total Cost PY, Total Cost YTD … ). With calculation groups you just create the box that shifts a measure into producing the time calculation that you want.
