We have a table in Power BI where we are trying to display the location, the current average of the location and then finally the average of the location based on the time period. Thus the location and the average stays constant, but the average across the location over the selected period changes with the period that one selects.
Do you have any advice on how we can implement this? Since the first two columns is linked to only the last ID/row (relationship) but the last column must go back to get the average across the selected period.

Looking for some help to calculate the cost increase/decrease between two date points per product. I would like to display any increases/decreases per item. Each item in the list are part of a BOM for an overall product. An example scenaro is needing to show any cost differences between 2022-03-01 & 2022-04-01 which would show changes in A ($0.50) and C ($0.20).
I'm guessing I would need to utilize the MAX/MIN functions in a measure, but having trouble creating a measure that compares each item. There are too many date points to due the calculation per date via a new column and all the data is unpivoted.
2 date values are selected via the standard PBI slicer visual
The underlying data format in PBI is displayed below:

I have 2 columns one containing order place time and another containing order delivered time and I have created a custom column where we calculate the delivery time in (dd:hh:mm:ss) format now I wanted to calculate average delivery time (i.e average of delivery time in (dd:hh:mm:ss) format).
can any one please suggest me any dax code for the same.
I just want to select a range of days in a slicer and show in a table the number of days for each month/period (month-year).
I used DAX to create a table with the information I need and I don't have problems with the periods (first column), it changes dinamically, the problem is the column "Days" (second column) because it's always showing the total number of days for each month.
Here my DAX code
SelectedPeriods = GROUPBY(DimDate;DimDate[Period];"Days";COUNTX(CURRENTGROUP();DimDate[DateKey]))
Here the result
What I expect is:
2 for april, 31 for may, 1 for june
This is an issue with execution order.
SelectedPeriods = GROUPBY(DimDate;DimDate[Period];"Days";COUNTX(CURRENTGROUP();DimDate[DateKey]))
Generates a calculated table. These are calculated when the data model is refreshed and stored in it. They are not refreshed each time a connected dimension is changed within a dashboard.
In your case, while changing date filters may hide rows from this table the number of days remains fixed at the number calculated initially when there was no filter context on the data i.e. counting all days in the month.
If you want the result to change then you need to use a measure instead of a calculated table. Measures react to the current filter context within the report and so will adjust their output each time a slicer is changed.
The needed measure will depend on your model but might be something as simple as:
CountOfDays := CountRows(DimDate)
I am trying to do some time based calculations on my budgeting data but struggling to understand where I'm going wrong or if my data structure would even support what I'm trying to do.
As per the image above, this is my raw data. ie. A monthly budgeted and actual total for each cost centre that is being imported from an excel spreadsheet.
I am trying to calculate a YTD budget and YTD Actual figure per cost centre based on the monthly totals. Ideally I would like all of this data displayed in a table that I can then use slicers to segment/pivot.
When using the CALCULATE() function in a measure, I am unable to select my cell value for each date and cost centre.
eg.
YTD Actual = CALCULATE( [Actual MTH] , DATESYTD('Dates'[Date], "30/6"))
returns the error
The value for 'Actual MTH' cannot be determined. Either 'Actual MTH'
doesn't exist, or there is no current row for a column named 'Actual
MTH'.
Any assistance with getting a greater understanding of the issue here would be appreciated.
Thanks
Try something like this for your measures:
YTD Actual = TOTALYTD(sum([Actual MTH]),'Dates'[date],ALL('Dates'[date]),"30/6")
I am working on a report that has data by month. I have created a measure that will calculate a cost per unit which divides the sum of dollars by the sum of production volume for the selected month(s):
Wtd Avg = SUM('GLData - Excel'[Amount])/SUM('GLData - Excel'[Production])
This works well and gives me the weighted average that I need per report category regardless of if I have one or multiple months selected. This actual and budget data is displayed below:
If you take time to total the actual costs you get $3.180. Where I am running into trouble is a measure to sum up to that total for a visual (This visual does not total sadly). Basically I need to sum the aggregated values that we see above. If I use the Wtd Avg measure I get the average for the total data set, or .53. I have attempted another measure, but am not coming up with the correct answer:
Total Per Unit Cost = sumX('GLData - Excel','GLData - Excel'[Wtd Avg])/DISTINCTCOUNT('GLData - Excel'[Date])
We see here I return $3.186. It is close, but it is not aggregating the right way to get exactly the $3.180:
My Total Per Unit Cost formula is off. Really I am simply interested in a measure to sum the post aggregated Wtd Avg measure we see in the first graph and total to $3.180 in this example.
Here is my data table:
As you probably know already, this is happening because measures are dynamic - if you are not grouping by a dimension, they will compute based on the overall table. What you want to do is to force a grouping on your categories, and then compute the sum of the measure for each category.
There are 2 ways to do this. One way is to create a new table in Power BI (Modeling tab -> New Table), and then use a SUMMARIZE() calculation similar to this one to define that table:
SUMMARIZE('GLData - Excel',[Category],[Month],[Actual/Budget],"Wtd Avg",[Wtd Avg])
Unfortunately I do not know your exact column names, so you will need to adjust this calculation to your context. Once your new table is created, you can use the values from that table to create your aggregate visual - in order to get the slicers to work, you may need to join this new table to your original table through the "Manage Relationships" option.
The second way to do this is via the same calculation, but without having to create a new table. This may be less of a hassle. Create a measure like this:
SUMX(SUMMARIZE('GLData - Excel',[Category],[Month],[Actual/Budget],"Wtd Avg",[Wtd Avg]),[Wtd Avg])
If this does not solve your issue, go ahead and show me a screenshot of your table and I may be able to help further.
