Visual calculation: running sum - sorting issue

[BenediktW]

Hello together,

I ve tried to utilize the new visual calculations to calculate running sums (cumulative percentage sales per customers as running totals).

Anyhow, I have the problem that the running sum gets calculated based on the alphabetical order of the category. Not on the sales volume (how I want it to be), on which the table is sorted. Is there any solution for this?

Thank you very much!

On the "Anteil_am_Gesamtumsatz" you can see the correct order. Anyhow the running sum is not calculating based on the sorted order but on the alphabetical order of my category.

Finally I found a solution without runningsum but with visual calc, which is working properly:

FORMAT(SUMX( WINDOW(1, ABS, 0 ,REL, ALLSELECTED([Customer, ],  [Sales]), ORDERBY([Sales], DESC

)), [Share total Sales]) , "Percent")

[lbendlin]

please show the visual calculation formula

[BenediktW]

That is the formular for running sum

My visual is sorted like this (based on Sales): 

However, as soon as I enter the visual calculation area, it automatically ignores the sorting of the table and just takes the alphabetical order of my category (Customer):

confirmed as a bug

it's not a bug, it's how it was implemented right now. What do you expect? Do you want the visual matrix to _always_ be sorted on whatever is the visual?

[lbendlin]

it's not a bug, it's how it was implemented 

that means the implementation was buggy 🙂

[jeroenterheerdt]

no, that was intentional. It follows the model sort order, such a sorting columns. Just blindly following the sort order of the visual is not the only choice.

Unless specified otherwise with PARTITIONBY or ORDERBY, yes! 

[jeroenterheerdt]

thanks for letting me know. What about the sort order from the model? And how about functions that don't have the ORDERBY and PARTITIONBY parameter, like RUNNINGSUM?

[BenediktW]

Thank you for the feedback, in my case: I cannot take simply any sorting order from the model as the sorting order must be based on a measure here. Thats why I currently see no way how to use the runningsum calculation for my advantage. 

When a "visual" calculation is ignoring the set-up of my visual, but is taking randomly alphabetical order of the category (my model is not sorted alphabetically) I dont really see the point.

This is also declared as a issue in various reviews (e.g. : DAX Fridays #225: RUNNINGSUM | Visual calculation functions - YouTube)   Minute 2:30)) 

In case I missed it: is there any option influence the runningsum sort-oder (besides query editor)?

there is not yet, we are actively thinking through what this should look like. Please feel free to give your input on this form: https://forms.office.com/Pages/ResponsePage.aspx?id=v4j5cvGGr0GRqy180BHbR-XFZhNDe99FoNSD_SJIDNlUNkNR...
