Ofcourse this can be a parameter selected by the user. You can Chose the number of averaging periods (from 2 up to 12). However, I've created another solution that is more flexible.

Hi was a small mistake in the code in the 4th value VAR Ranking = COUNTROWS ( WeeksOnAndBefore )įILTER ( FibonacciTable, FibonacciTable = Ranking ),įibonacciTable * S1 + FibonacciTable * S2 + FibonacciTable * S3 + FibonacciTable * S4 VAR WeeksOnAndBefore = FILTER ( SelectedWeeks, 'Date' > W & 'Date' <= CW ) VAR SelectedWeeks = ALLSELECTED ( 'Date' ) VAR S1 = CALCULATE (, 'Date' = W - 3, ALLSELECTED ( ) ) VAR S2 = CALCULATE (, 'Date' = W - 2, ALLSELECTED ( ) ) VAR S3 = CALCULATE (, 'Date' = W - 1, ALLSELECTED ( ) ) VAR S4 = CALCULATE (, 'Date' = W, ALLSELECTED ( ) ) Recursion involves a function that calls itself. A recursive implementation and an iterative implementation do the same exact job, but the way they do the job is different. There are many different implementations for each algorithm. with real data would be VAR LastDateWithData 'Table' and then VAR W = YEAR ( LastDateWithData ) * 100 + WEEKNUM ( LastDateWithData ) Binary sorts can be performed using iteration or using recursion. VAR W = CALCULATE ( MAX ( 'Table' ), REMOVEFILTERS ( ) ) Please refer to the sample file with the solution You need to understand that this is a limitation of the DAX language for the time being, hopping future updates will curry new features of the language such as loops that can help performing recursive calculations much more easier.Īlso Please note that there is a rounding error with this method and the results shall not be 100% accurate. Slicing by different column(s) might require changing the code. Please note that such reports should have limited flexibility in terms of the columns used to slice. However, your real data might not be as I expected, therefore some changes might be required. You need to import the Fibonacci table as is and use the DAX as is. The solution is a bet difficult to understand and it should be carefully design to suit each case independently (cannot be generalized) nevertheless, what ever the chosen details of the solution, the general idea remains the same. A helper table that suits your case shall be needed to handle the recursion. When I hear “Isn’t it cool that you can do X in X?” my first thought is “Yeah, that sounds cool” but my second thought is “But why would you want to do that? Sounds like it could be really hard.” I’m starting to appreciate that there are sometimes long-term benefits to these sort of recursive tool uses even if they’re not optimal in the short run.Hi fully recursive problems cannot be handled by DAX straight forward. You can use the same navigation commands in the help system that you can when editing text, you can execute code snippets in place, etc. But the most subtle benefit is the compound effect of self-reference. For another, you avoid the risk of being distracted by something you see when you’re using your web browser. What’s the advantage to the former?įor one thing, using Emacs help inside Emacs works without a network connection. But you can also type your questions into a search engine without having to learn an arcane help API. You can pull up help on Emacs from inside Emacs.

For example, part of the elevator pitch for Emacs is that it’s self-documenting. Otherwise you go down the black hole of becoming absorbed in your tool and never using it for work.Įven though I’ve used Emacs for a long time, I’ve never understood the recursive fascination some people have with it. But as with writing a recursive procedure, there has to be a base case, a point at which you stop recursing. There’s a kind of consistency that results, and there can be a compound return on effort. At some point you hit diminishing return and it’s time to start chopping.īut there are benefits to self-referential systems, such as macros that use Lisp to generate Lisp, or writing a C compiler in C, or using Emacs to tweak Emacs. If it’s your job to cut down a tree, there’s some benefit to sharpening your ax, but you can’t only sharpen your ax.

There’s a danger of becoming obsessed with one’s tools and never getting around to using them.
