In a pivot table that plots values against a timeline it is possible to right-click the table, select "Show values as..." and have them appear as a percentage of a particular day.
I'm trying to recreate the same behaviour using DAX measures: I would like to have a measure that shows each day's price as a percentage of the first day of the year.
I've successfully created a measure that correctly identifies the first date of the year, i.e. the baseline:
FDate:=CALCULATE(FIRSTDATE(Prices[Date]),ALLEXCEPT('Calendar','Calendar'[Year]))
However, I can't figure out how to use this FDate to get that day's price (needed as the baseline for further calculations):
CALCULATE([Sum of Price], ALLEXCEPT('Calendar','Calendar'[Year]), FILTER('Prices', 'Prices'[Date]=[FDate])) returns each day's price, not the first date's.
CALCULATE([Sum of Price], FILTER(ALLEXCEPT('Calendar','Calendar'[Year]),'Calendar'[Date]=[FDate])) ignores the YEAR report filter and returns the price of the very first date in my calendar table and not the first date in the year I've filtered for.
Any pointer in the right direction would be greatly appreciated!
Thanks
Here's the solution:
VAR FirstDate = [FDate]
RETURN(
CALCULATE([Price],
FILTER(ALLEXCEPT('Calendar','Calendar'[Year]),'Calendar'[Date]=FirstDate))
)
Variables allow you to define measure in a certain filter context but to leave it unaffected by subsequent filter contexts - that at least is my layman's understanding.

I am currently attempting to use DAX queries to calculate the proportion of the balance attributed to each State in my analysis cube, from the following image:
I currently have a Sales table with a ReportDateKey that joins a ReportDate table that has a DateKey
If I use the following statement:
AllCurrentBalanceByDate:=CALCULATE([TotalCurrentBalance],ALLSELECTED())
It gives me the overall total, ignoring the date altogether, which is a useless figure.
If I enter the following query and display it in the excel spreadsheet:
AllCurrentBalanceByDate:=CALCULATE([TotalCurrentBalance],ALLSELECTED('Report Date'[Month]))
it is returning the same data as found in the Balance column. Again, useless. I need a total for each month, so that I can calculate the state balance / overall total for that month to get the proportion/percentage attributable to that State.
What am I doing wrong?
So if you want your measure to ignore whichever State is selected, you need to include the State columns in your ALL filter.
Also I suppose you want to use ALL instead of ALLSELECTED as your overall balance per month shouldn't be affected by external filters on state (but this depends on your use case)?
AllCurrentBalanceByDate:=CALCULATE(SUM([CurrentBalance]),ALL(Geography[StateName]))
I am using following query to get records count on month wise and it is working fine:
SELECT MONTH(dte_cycle_count) MONTH, COUNT(*) COUNT
FROM inventory
WHERE YEAR(dte_cycle_count)='2021' --OR (MONTH(dte_cycle_count) = '1' OR MONTH(dte_cycle_count) = '12')
GROUP BY MONTH(dte_cycle_count);
Problem:
Now I need to bind rollover calendar so user can scroll or click on next or previous button the next 12 Months record will be visible.
eg. Current month is MARCH, So default records will be from APR2020 to MARCH2021. If user click on previous then records will come MAR2020 to FEB2021.
How I can achieve this?
Please let me know if need more information. I will try my best to provide.
I think what you are after is a date list from which to join to your inventory table.
Like a numbers table, build a static table with columns for date, year, month, populated from whenever you need to far in the future.
You then select from this, applying your filtering range critera, and join to your inventory table.
For an efficient query, ideally your inventory table should have the relevant date portions eg year and month stored to match.
You don't want to be using functions on a datetime to extract the year or month as this is not sargable and will not allow any index to be used for a seek lookup.
I am trying to apply some Time Intelligence functions in my PowerPivot workbook concerning projects and money received for them. I have three relevant tables; Matters, Payments, and a Date Table.
Each matter has a creationDate, and a closureDate(from a linked table). Likewise, each payment has a date. I have reporting set up decently, but am now trying to use Time intelligence to filter this a bit more clearly.
How can I set a PowerPivot Pivot Table up so that the only Matters which show are those which existed within the period selected. e.g. If I select a slicer for 2014, I don't want to show a matter created in 2015, or one which was closed in 2013. The matter should have been active during the period specified.
Is this possible?
You want to show all the matters EXCEPT those where the CreationDate is after the upper limit of the date range you are looking at or the ClosureDate is before the lower limit of the date range you are looking at.
Assuming you have a data structure like this, where the left-hand table is the Matters and the right-hand one is the Payments:
If you have a calculated field called [Total Payments] that just adds up all the payments in the Payments table, a formula similar to this would work:-
[Payment in Range]:=IF(OR(MIN(Matters[Creation Date])>MAX('Reporting Dates'[Date]),MAX(Matters[Closure Date])<MIN('Reporting Dates'[Date])),BLANK(),[Total Payments])
Here is the result with one month selected in the timeline:
Or with one year selected in the year slicer:
NOTE: in my example, I have used a disconnected date table.
Also, you will see that the Grand Total adds up all the payments because it takes the lowest of all the creation dates and the highest of all the closure dates to determine whether to show a total payment value. If it is important that the Grand Total shows correctly, then an additional measure is required:
[Fixed Totals Payment in Range]:=IF(COUNTROWS(VALUES(Matters[Matter]))=1,[Payment in Range],SUMX(VALUES(Matters[Matter]),[Payment in Range]))
Replace the [Payment in Range] in your pivot table with this new measure and the totals will show correctly, however, this will only work if Matters[Matter] is used as one of the fields in the pivot table.
Use filters & the calculate function.
So, if you're Summing payments, it would look like.....
Payments 2014:= CALCULATE( SUM([Payments]), DateTable[Year]=2014)
The Sum function takes the entirety of payments & the filter function will only capture payments w/in 2014, based on the data connected to your date table.
I've created a new measure which uses [TotalSales] and 'SAMEPERIODLASTYEAR' to calculate the previous year's sales, see below:
=CALCULATE([TotalSales], SAMEPERIODLASTYEAR(Dates[Date]))
This all works fine if I create a pivot that displays individual dates (e.g. 01/01/2015) and then the new measure 'previous year sales' value next to it. My problem occurs when I want to change the pivot and display previous year sales by year, quarter or month - with any of these options I get no sales value.
I'm using a 'Dates' table which is linked to the Sales table.
Am I right in thinking I can re-aggregate sales in this way? I have seen an error message which says something about not been able to aggregate a non-contiguous value or date.
I've had a good look to see if anyone else has experienced the same problem, but can't see anything. Any guidance would be helpful.

Yes you can re-aggregate in this way. Your formula is correct would handles the changes to the aggregation level.
I would check that your 'Dates' table is marked as a date table. Ensure that the year, quarter & months are in this date table and not in your Sales table. Make sure that your date table has one record for each day between the beginning of your sales data set and the end. Check behavior in Power View if you are using Excel 2013.
I've searched here and elsewhere on the web and have not found this exact problem/solution.
I'm building an rdlc report using the MS reportViewer - the report I'm creating is based on an existing spreadsheet where the average price across 6 months is calculated individually for each month, then the average of those prices is calculated as the 6 month period average price. Whether I agree with that methodology or if it's correct is irrelevant, I just need to know how to get an rdlc to do this.
For example:
Month Price1 Price2 Delta
May-12 $31.54 $30.03 $1.51
Jun-12 $36.27 $34.60 $1.67
Jul-12 $44.19 $42.00 $2.19
Aug-12 $38.96 $37.06 $1.90
Sep-12 $36.89 $35.08 $1.81
Oct-12 $35.57 $33.97 $1.60
Average $37.24 $35.46 $1.78
(sorry for the lack of a screen snip, I'm new and the system won't let me post an image...)
I've created a tablix that does the monthly averages computation - I use a group in the table to group the 6 months of data by month (and then hide the hourly price data so you only see the month total row) but I'm stuck on how to calculate the bottom row of the table which is the average of each column. (the average of the averages is not the same as the average of all 6 months of prices from the underlying data - that's what I've learned in this process... IOW, that was my first solution :-) )
What I tried to do to get the average of the averages was give the month total cell a name, MonthlyAvgPrice1, then in the bottom row, used this expression:
Avg(reportitems!MonthlyAvgPrice1.Value)
As I kind of expected, this didn't work, when I try to run the report, it gets a build error saying "The Value expression for the textrun 'Price1PeriodAvg.Paragraphs[0].TextRuns[0]' uses an aggregate function on a report item. Aggregate functions can be used only on report items contained in page headers and footers."
Hopfully I've explained this well, does anyone know how to do this?
Thanks!

Actually it is not clear from the question that how are you in particular binding the data to the report items, But from the given information what I understand is that you can
Try like this:
Right Click the tablix row and insert a row below
In the cell where you want to have this Average of Averages insert the following expression
=Sum(Fields!Price1.Value)/6
and similarly insert expression =Sum(Fields!Price2.Value)/6 and =Sum(Fields!Delta.Value)/6 in the other cells where you want to display the Averages
Of Course, you will change the Field names Price1,Price2 etc to the fields that you are getting the values from.
