    In DAX world, table filters are not healthy when it comes to performance (report, code, capacity usage etc.).
    I have seen many TH-camrs making this mistake, and people learn those methods without knowing the impact (Example: dimCustomer in YT Video may have x number of records where as in reality it might be (x+n) rows with hundreds of columns.
    Was happy to see REMOVEFILTERS(dimCustomer[Customer Name]) at last somewhere instead of ALL(dimCustomer).
    Thank you

    A "must" for anybody looking to use DAX. It makes clear what the "context" concept means and what's the rationale to use measure or calculated columns , not just choosing one or another because it's the right way but to understand the reason for that.

    I have a question though: Is there a way to filter by using only part of the value and not the whole word? For example instead of finding all Sales for which [Product Category] ="Hair", can we find all Sales for every [Product Category] that contains let's say the letters "*AI*" somewhere in the [Product Category] field?

    Hi, is there a way to get a specific date values thru DAX e.g. getting the sales every 1st of the month then comparing it with current sales value. I tried using CALCULATE and FILTER but the 1st day sales only shows on the total rows but doesn’t show up on each rows. It will only show the per row values if the selected report date is 1st of the month. Hope you can cover it in your future video

    In the calculated columns that you used to classify the customers what if you had to have a slicer by product and the class of client had to change depending what product you select? Everything I read says that calculated columns are static and calculated when the table is built but you can't use a measure has the first columns of a matrix so I can't think of a way to resolve this.

    I still cannot get my head around this. So I started tampering with the same expression and when I applied the same code but without the calculate the same numbers were returned for customers regardless of whether I used Allcustomers or just Customers. It seems that the row context of fctsales[sales], which is a calculated column, overrides the preceding row context on customer, that is Allcustomer behaves the same as customer alone. If you could please clarify this would appreciate it.

    Hi Bas! Thanks a lot for this video and all of them, i'm new at dax and your channel is being really useful.
    I'm having trouble understanding context transition.
    I've tried appying the calculate(sum()) formula, but it doesn't respect the calendar table filter. If i use a meassure it works correctly, but i think i need a calculated column with the amount, since the goal is to label the customer according to 3 categories for the amount of income of each one. Could you give a hint? thanks in advance.
    Kind regards.

    In the last example, would it not be better to remove all filters on the dimCustomer table and not just on Customer Name that may not even be unique? There may still be a filter on customer no or customer id or something.

    • @HowtoPowerBI
      @HowtoPowerBI  2 ปีที่แล้ว +1

      if you would add a further breakdown to the visual (for example customer segment) it would lead to a different result (% of overall total vs subtotal) .. just depends on what you are looking for -> work with the minimum number of columns to reach your goal

    thanks for your tutorial!
    How do you make a new line when you write the commands? Is wrapping just to make the formula more readable?

      yes, exactly - just makes it more readable (and easier to spot mistakes) -> shift + enter .. th-cam.com/users/shortsI5HSerFTSDI?feature=share
