I have a Qlik Sense app using different kind of charts, among them, a KPI with 5 measures.
The app's data is coming from multiple tables.
The problem I have is that 3 of the measures in the KPI are calculated using Columns(), but I don't know to what columns the expressions are referring to.
For example:
Percent: =Column(1)/Column(2)-1
Arrow Up: =IF(Column(3)>0,'▲',null())
Arrow Down: =IF(Column(3)<0,'▼',null())
So, the app's data is coming from multiple tables, there is no table chart in the app. How can I determine to what "column" the expressions is referring to?
The column() function refers to the expressions in the object you are working with not to the underlying data. So that looks like column 1 is Sales for this year and column 2 is Sales for last year

I have a matrix table created with Rows as Days ,Columns as Months and quantity of rainfall as the data field(got all this information from same table 'Rainfall'). I have taken this data from a dataset containing multiple tables in SQL. All of this information displays properly.
Now I have many tables with date field in my dataset in tables other than 'Rainfall'.
In the data field of the matix I need to be able to add my own colors using a Switch case.
The Condition I need is "if a certain date from one table matches the date in my report then i want xxx colour."
eg: there is a table called fertilization which has 3 dates. Now if these 3 dates also exists in my matrix then that block should be colored blue.
Can anyone help me. Thanks!
You can also manage it from sql side while retrieving data from Rainfall table.
You can do this using by right clicking the field that you want the dynamic color on and selecting properties. Select Border and then where it says color hit, click the Fx button. Here you can write a custom expression that will change the background color based upon your code.
I have a report that in the values I have 2 data sets, and then grouping by a location to display the data. If I use the one location within 1 dataset then sure one of the averages I am displaying is perfect but the other is incorrect showing the same result across the board.
No down I need to join these together to get an outcome.
here is what I have:
Values:
1. =Avg(Fields!Rating.Value)
2. =((sum(Fields!Low_rating.Value,"MIN_MAX_CCR") + sum(Fields!Max_rating.Value, "MIN_MAX_CCR")) / 2 ) / Count(Fields!Case_ID.Value, "MIN_MAX_CCR")
Category Grouping:
1.=lookup(Fields!CaseID.Value,Fields!Case_ID.Value, Fields!location.Value,"MIN_MAX_CCR")
So the first field is from the current dataset, the second is from the MIN_MAX_CCR dataset, the location is from the first data set, and then getting the data set for the case_ID.
Now when I run this I get this lovely error:
System.Web.Services.Protocols.SoapException: The Group expression for the grouping ‘Chart8_CategoryGroup’ refers to the field ‘location’. Report item expressions can only refer to fields within the current dataset scope or, if inside an aggregate, the specified dataset scope. Letters in the names of fields must use the correct case.

I just cant see a way around this - I cant combine the data in one query due to the nature of the query differences.
You are trying to return location from MIN_MAX_CCR, but it doesnt exist.
I would read the documentation or intellisense hints on the Lookup function to learn how to write it correctly.
I have sales data that I'd like to plot on my chart. However, at a specific point in time, we had a change taking place I'd like to ensure is clearly visible in the chart, preferably by dividing the sales data (which is stored in a single SQL Server column) into two different chunks, which would allow me to then treat them as different data series.
I used to solve this in Excel by storing the post-event data in a different column (by simply dragging them to a different column), and thus I was able to treat them as a different series (the blue and green line in the chart below. The red and orange line are pre-event and post-event averages):
I'd like to reproduce this effect in SSRS, but am not sure how to tackle it. I've tried using an approach where I added two category groups, both pointing to the date-time column, and applying filters to them (one <= the cutoff date, the other >=).
I then added my sales data twice, with the idea I could somehow connect them to the individual category groups, but that does not seem possible.
Has anyone tried anything like this before, or would have a different approach to achieve what I'm trying to get?
Thanks!
I managed to get this to work, and figured I'd share how to do it.
My dataset contains a field called DATEKEY, which stores the date in the format YYYYMMDD. It's possible to use this in an expression and evaluate the date for a specific row. In case the expression evaluates to true, we display the value. If not, we display a blank string.
In case we want to show the values prior to the date, the expression would be:
=IIF(Fields!DATEKEY.Value <= 20130601, Avg(Fields!My_NUMBER.Value), "")
The second series can then be made by reversing the symbol:
=IIF(Fields!DATEKEY.Value >= 20130601, Avg(Fields!My_NUMBER.Value), "")
The graph then looks like this:
Say I have a table in a PowerPivot that looks like this:
For each row, I want to find the minimum value across Columns 1, 2 and 3 and display that value in the column "MinColumn". The built-in MIN function only seems to operate on a column though, and not a row.
Is there any way to do this, other than some kind of nested IF expression? If we have a lot of columns to compare, that would get very messy, very quickly.
PowerPivot/DAX does some great column-based stuff (to be expected given it's use of xVelocity) but seems to get complex when you start looking at row-level functionality.
Another option is to push the calculation down to the source.
For example, if your source is a database table, you could create a view (or simply use a named query) and calculate the MIN (across the 3 other columns) before you pull the data into PowerPivot.
Note: the TSQL version would also be fairly ugly, PIVOT + MIN() OVER()
I have a report (RS2005, against a MSSS2005 instance) which I have inherited. It shows a basic table of data: a handful of key fields which are used to group rows together, a few basic numeric fields, then a number of dated ('bucketed') fields (e.g. 1 month away, 2 months, 6 months, a year, 2 years, etc.)
The user would like to group together these dated fields in aggregated groups and be able to collapse or expand the columns as you can the rows. So we'd be able to show the next year's values' subtotal or expand it to break it out by month. Hiding the invidual months if the subtotal is shown.
This is basic pivot table behaviour (and can be done with the Group/Subtotal feature on Excel - that's the closest analogous behaviour I could use to describe the requirements).
While grouping by rows seems trivial in RptgSvcs, grouping columns and collapsing a group into a single subtotal and blowing it out again, seems hard to impossible.
Unless someone knows better?
You should be able to do this by selecting the columns that you would like to hide and set their visibliity to be hidden.
Then set the toggle item on the hidden columns to be the textbox that shows the subtotal.
This textbox will then have the [+] symbol on it, and clicking will show/hide the your month-by-month breakout(the hidden columns).
On the right hand side of the table control on your report (RDL file), you should see icons representing the detail and grouping information for the table.
Here you can see whether or not a grouping has a header/footer and how it is calculated e.g. =SUM(fields!mySalesValue)
You can also set things like whether it is collapsed and so on
