Single aggregate column / running value sum on chart - sql

We're currently porting some excel reports to SSRS. One of those reports has a graph where the last column is the MTD (Month to date) average for both series (Availability and Availability Goal) just like the example below:
I did some research about RunningValue() but whenever I did it it would add a second bar to my graph (the running value would have the same group).
Is it possible to have only one aggregate column (just like the screenshot) ?
Thanks in advance,

One way would be to force the average through the SQL query. For example, if your resulting table shows days of the month, and the Availability value, you could UNION a "dummy" day (max days of the month + 1) with the averaged value. You can either add an addition column to your SQL for the label names, i.e. the "dummy" day would show "Average", or in SSRS you can change the Label expression to replace the last value with a text.

Limiting data on monthly basis from start date to system date dynamically in Tibco spotfire

I've tried limiting data on monthly basis in spotfire and it's working fine.
Now I'm trying to do like getting the records from the current date to month start date.
For suppose if the current date is Sept 21, then i should get the records from Sept 21 to Sept-01(dynamically).
I have a property control to input the number of months.
The easiest way to do this is with Month and Year. For example, in your visualization:
Right Click > Properties > Data > Limit Data Using Expressions (Edit)
Then, use this expression:
Month([TheDate]) = Month(DateTimeNow()) and Year([TheDate]) = Year(DateTimeNow())
This will limit the data to only those rows with the current Year/Month combination in your data column. Just replace [TheDate] with whatever your date column name is.
In other places, you can wrap this in an IF statement if you'd like. It's redundant in this case, but sometimes helps with readability.
IF(Month([TheDate]) = Month(DateTimeNow()) and Year([TheDate]) = Year(DateTimeNow()),TRUE,FALSE)
#san - Adding to #scsimon answer. If you would like to precisely limit values between 1st of the current month to current date, you could add the below expression to 'Limit data using expression' section.
[Date]>=date(1&'-'&Month(DateTimeNow())&'-'&year(DateTimeNow())) and [Date]<=DateTimeNow()

Creating a DAX pattern that counts days between a date field and a month value on a chart's x-axis

I am struggling with a DAX pattern to allow me to plot an average duration value on a chart.
Here is the problem: My dataset has a field called dtOpened which is a date value describing when something started, and I want to be able to calculate the duration in days since that date.
I then want to be able to create an average duration since that date over a time period.
It is very easy to do when thinking about the value as it is now, but I want to be able to show a chart that describes what that average value would have been over various time periods on the x-axis (month/quarter/year).
The problem that I am facing is that if I create a calculated column to find the current age (NOW() - [dtOpened]), then it always uses the NOW() function - which is no use for historic time spans. Maybe I need a Measure for this, rather than a calculated column, but I cannot work out how to do it.
I have thought about using LASTDATE (rather than NOW) to work out what the last date would be in the filter context of any single month/quarter/year, but if the current month is only half way through, then it would probably need to consider today's date as the value from which to subtract the dtOpened value.
I would appreciate any help or pointers that you can give me!
It looks like you have a table (let's call it Cases) storing your cases with one record per case with fields like the following:
casename, dtOpened, OpenClosedFlag
You should create a date table with on record per day spanning your date range. The date table will have a month ending date field identifying the last day of the month (same for quarter & year). But this will be a disconnected date table. Don't create a relationship between the Date on the Date table and your case open date.
Then use iterative averagex to average the date differences.
Average Duration (days) :=
CALCULATE (
AVERAGEX ( Cases, MAX ( DateTable[Month Ending] ) - Cases[dtopened] ),
FILTER ( Cases, Cases[OpenClosedFlag] = "Open" ),
FILTER ( Cases, Cases[dtopened] <= MAX ( DateTable[Month Ending] ) )
)
Once you plot the measure against your Month you should see the average values represented correctly. You can do something similar for quarter & year.
You're a genius, Rory; Thanks.
In my example, I had a dtClosed field rather than an Opened/Closed flag, so there was one extra piece of filtering to do to test if the Case was closed at that point in time. So my measure ended up looking like this:
Average Duration:=CALCULATE(
AVERAGEX(CasesOnly, MAX(DT[LastDateM]) - CasesOnly[Owner Opened dtOnly]),
FILTER(CasesOnly, OR(ISBLANK(CasesOnly[Owner Resolution dtOnly]),
CasesOnly[Owner Resolution dtOnly] > MAX(DT[LastDateM]))),
FILTER(CasesOnly, CasesOnly[Owner Opened dtOnly] <= MAX(DT[LastDateM]))
)
And to get the chart, I plotted the DT[Date] field on the x-axis.
Thanks very much again.

Creating a calculated column (not aggregate) that changes value based on context SSAS tabular DAX

Data: I have a single row that represents an annual subscription to a product, it has an overall startDate and endDate, there is also third date which is startdate + 1 month called endDateNew. I also have a non-related date table (called table X).
Output I'm looking for: I need a new column called Categorisation that will return 'New' if the date selected in table X is between startDate and endDateNew and 'Existing' if the date is between startDate and endDate.
Problem: The column seems to evaluate immediately without taking in to account the date context from the non-related date table - I kinda expected this to happen in visual studio (where it assumes the context is all records?) but when previewing in Excel it carries through this same value through.
The bit that is working:I have an aggregate (an active subscriber count) that correctly counts the subscription as active over the months selected in Table X.
The SQL equivalent on an individual date:
case
when '2015-10-01' between startDate and endDateNew then 'New'
when '2015-10-01' < endDate then 'Existing'
end as Category
where the value would be calculated for each date in table X
Thanks!

Calculated columns are only evaluated at model refresh/process time. This is by design. There is no way to make a calculated column change based on run-time changes in filter context from a pivot table.
Ross,
Calculated columns work differently than Excel. Optimally the value is known when the record is first added to the model.
Your example is kinda similar to a slowly changing dimension .
There are several possible solutions. Here are two and a half:
Full process on the last 32 days of data every time you process the subscriptions table (which may be unacceptably inefficient).
OR
Create a new table 'Subscription scd' with the primary key from the subscriptions table and your single calculated column of 'Subscription Age in Days'. Like an outrigger. This table could be reprocessed more efficiently than reprocessing the subscriptions table, so process the subscriptions table as incrementals only and do a full process on this table for the data within the last 32 days instead.
OR
Decide which measures are interesting within the 'new/existing' context and write explicit measures for them using a dynamic filter on the date column in the measures
eg. Define
'Sum of Sales - New Subscriptions',
'Sum of Sales - Existing Subscriptions',
'Distinct Count of New Subscriptions - Last 28 Days', etc

ssrs dynamic value in text box and title

I have a report which runs weekly and in one of the tables it says week1, week2 etc all the way to the recent week (e.g. week28 currently)
This table is in the report and I would like the week28 value to be in the title. The title reads "summary report for" I want to place the week number at the end so every week the report is run it changes.
There are also a couple of other places I would like to place the dynamic value but i'm guessing the code will be the same.
Assuming you have a sorted dataset called "MyDataset" with a column that contains the week names called "Week", you could simply use the following expression:
=Last(Fields!Week.Value, "MyDataset")
This returns the last value in the Week column of MyDataset.
Alternatively, you could construct the week number using some of the date functions, for example the datepart function

How do I compute an average of calculated averages in MS reportviewer/rdlc?

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.
