I have a table with 3 columns in SAP Webi as shown in the picture.
In column "weekly average" I want to dynamically calculate the weekly average (from Monday to Sunday) of column "count".
Is it possible to do it with a variable? If not, any suggestions how to do it with other methods?
Thanks.
Yes, this can be done. Two steps: first create a variable to define a single value for each week, then another to return the average of those values.
For step 1, create a new variable ("Date Week") with the following definition:
=LastDayOfWeek([Date])
Then, in the report block (where your "Weekly Average" column is), create this formula:
=Average([Count]) in ([Date Week])
This should produce the result you want.

I have a dataset organized as following :
The column A is the name
The column B is the date
The column C is the value registered for that person in that day
How can i calculate for the whole dataset a mean of the value of that person in the 30 past days without manually ordering for name and making the mean checking the date?
Try the AVERAGEIFS function with the EDATE function giving you a one month window.
=AVERAGEIFS(C:C, A:A, "Jack", B:B, ">"&EDATE(TODAY(), -1), B:B, "<="&TODAY())
You can use a nested array formula (Ctrl+Shift+Enter instead of Enter):
=AVERAGE(IF($A$2:$A$15=A2,IF($B$2:$B$15>=TODAY()-30,$C$2:$C$15,""),""))
Add columns for these two fomulas:
=COUNTIF(A1:A4,"Jack")
=SUMIF(A1:A4,"Jack",C10:C13)
That will give you the count, and it will give you the sum. With those two you can calculate the mean.
That's the basic idea, anyway.
Of course, you can add another count for the date ranges. It's all the same sort of thing.
I am new to the use of Pentaho and let me know how it works the "Calculated Columns" option into "sql query" object.
I need to calculate the average value.
Calculated columns perform basic operations on other columns, on a Row by Row basis. You cannot use that to calculate the average of all values from another column, but you can use it to calculate the average of values from the same row.
The syntax follows Open Formula syntax (the same you have on Pentaho Report Designer).
So, for example, if you have columns A, B and C as "Date", "Quantity" and "Sales", you can define a new column, "Unit Price" using the formula
=[Sales]/[Quantity]
Another situation is the following: lets say you have 13 columns: "Customer", "Jan", "Feb", "Mar", ...
You can create a new column, the Avg value of the 12 months, by either using the Avg function or summing all 12 values and then dividing by 12:
=AVG( [Jan],[Feb],[Mar], ....)
And the values of that new column would be the avg value of the 12 months per customer.
But each formula calculation will only use values from the same ROW or results, it cannot reference other rows of data.
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
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.
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.
