dax

I want to create a simple percent change formula in power BI. Specifically, I want to evaluate month over month %change in cost. I know that percent change can be defined in different ways, so to be clear this is the formula that I am referring to: %change = ([current value] - [previous value])/[previous value]. Here is an example in Excel of what I want to achieve: I cannot find a way to target a specific row in a DAX formula. It seems that power BI only wants to include aggregate values such as sum, max, etc. As a final note, I know that PowerBI includes a percent change "quick measure".

I can't get a division correct with this sample data: Calculated column Another calc. column 48 207 257 370 518 138 489 354 837 478 1,005 648 1,021 2,060 1,463 2,164 2,630 1,818 2,993 2,358 3,354 3,633 4,332 5,234 4,885 6,108 4,514 6,008 4,356 6,888 4,824 7,382 7,082 5,988 7,498 6,059 4,865 4,192 3,816 2,851 2,768 2,093 2,207 770 397 149 178 336 167 124 18 What I'm trying to do is to create a new calculated column. For each row I want to get the value of Calculated column and divide it by the Total of Another calc. column . The Total of Another calc. column = 82826 This is the desired output

I would like to write a dax code in Power BI which calculate the sum of maximum values of each day. In one column there is a production data and on the second column there is the the date and time. The counter resets in the beginning of every day. I want to pick up the maximum value for each day and sum them up. Like, Sum = Max of Day1 + Max of Day 2 + ....... Max of Day N How is it possible? Thanks in advance Sample Data: Date Daily Counter 2/1/2018 12:00:00 AM 1 2/1/2018 6:00:00 AM 2 2/1/2018 12:00:00 PM 3 2/1/2018 6:00:00 PM 4.5 2/2/2018 12:00:00 AM 1 2/2/2018 6:00:00 AM 3 2/2/2018 12:00:00

I'm trying to create a column that has a total of values between 3 columns from 3 tables. How would I go about doing this? The 2 tables are tables of values that share an id, and they are both linked to a table of account by Id. The goal is to add up 3 columns, and place it into a table grouped by the Id. I've attempted summing them, trying to use the USERELATIONSHIP function, and creating a relationship between them. It seems to give very inaccurate results, as if it's summing all of the totals together, and passing them to each Id. That, or it won't let me use the column, as if it never
