I have one dataset Dataset1 and in that I am displaying data based on grouping. The data is like this
CityColumn CountColumn
City1 5
City2 3
The query of above datase is like this :
select count(*) as "CountColumn" from City group by CityColumn
Here in above dataset I have counted using grouping on CityColumn.
Now I have created another Dataset Dataset2 and in that The data is like this
CityColumn
City1
City2
City3
Now in dataset2 I have add one calculated field called TotalCount and used the Lookup Function the function is like this
=Lookup(CityColumn, CityColumn, CountColumn, "Dataset1")
but It gives me an error like
Lookup includes aggregate, rownumber, runningvalue, previous or lookup function. Aggregate, rownumber, runningvalue, previous or lookup function cannot be used in calculated field.
The first two values of the lookup function must refer to an identifying value in a column. In your case the City names must be in both datasets. Think of that as a primary key. The third value is the one you want to display from the second dataset. So it should look more like this:
=Lookup(Fields!CityColumn.Value, Fields!CityColumn.Value, Fields!CountColumn.Value, "Dataset1")
Make sure that Dataset1 has the column named CountColumn that you are trying to lookup. Keep in mind that this only looks up individual rows, not aggregates. If you want to work with aggregates you can do that on top of the lookup function.
EDIT:
Since Lookup functions are not allowed in calculated fields, you'll need to use it in the Value expression in your pie chart. It should look like this:
Note that the lookup function has to be in an aggregate like a sum function for it to work as a chart value.
Instead of adding it as a calculated field in the DataSet, simply add the expression into an empty column within the details rows of the report.

My tablix has following columns
Country, City, College, totalstudent,passedstudent,failedstudent
I have a parameter "GroupBy" with values "country/city/college". So, when i select one of the parameter, my tablix should be grouped by that parameter and only so that parameter column + total,passed,failed columns
For eg. If user selects GroupBy = "City" then, the tablix will show
City, totalstudent, passedstudent, failedstudent
The values in total, passed and failed is total sum grouped in that city.
The similar logic should be applied to country and college also.
So, far i am able to show the all columns with grouping applied by country, then city and then college. (which is one of simple ssrs grouping)
(My need is to only apply the one grouping based on parameter and only show that particular columns)
Note: I have a raw dataset that has all these values retrieved using inline sql from my sql database.
(Dataset1: Country,City,College,totalstudent,passedstudent,failedstudent)
You can group your table by an expression. In your group properties you would write something like this:
=Switch(Parameters!GroupBy.Value = "City", Fields!City.Value
, Parameters!GroupBy.Value = "College", Fields!College.Value
, ...)
The other columns should be able to just use regular Sum functions and work with any grouping.
I tried the different approaches (I went through the last/3rd approach)
Used multiple tablix for the different grouping conditions and used the parameter to hide/show the correct tablix in the report
Pitfall: It is awfully slow since I have 4 different grouping conditions and putting in 4 different tablix.
Using the dynamic grouping concept as illustrated at ( http://www.advancedssrs.com/2014/01/how-can-i-use-dynamic-grouping.html) which is good. But It was not suitable for my situation as it was also comparatively slow while i try to sort the columns in SSRS. (I need the sorting feature in all columns)
Created a new parameter (groupby) which is used to mimic the scenario of tabs. So, when the user selects one of the value ( Country/City/College), I am grouping my SQL result based on this groupby parameter value using conditional grouping statements and returning result back to SSRS.
SELECT
CASE WHEN #GroupBy = 'Country' THEN CountryName
WHEN #GroupBy = 'City' THEN CityName
WHEN #GroupBy = 'College' THEN CollegeName
END AS GroupTitle,
SUM(totals) AS totalstudent,
SUM(passes) AS passedstudent,
SUM(fails) AS failedstudent,
FROM #temp
GROUP BY CASE WHEN #GroupBy = 'Country' THEN CountryName
WHEN #GroupBy = 'City' THEN CityName
WHEN #GroupBy = 'College' THEN CollegeName
END
ORDER BY 1
DROP TABLE #temp
Now, I use the GroupTitle in my first column and rest of the aggregated values in the remaining columns in a single tablix.
The output looks like:
When creating your dataset, don't directly write your query in the box --- instead, use expression.
="SELECT " + Parameters!GroupBy.Value + ", passedstudent, failedstudent
FROM Table GROUP BY " + Parameters!GroupBy.Value
Your "passedstudent" and "failedstudent" will be some aggregation, either COUNT or SUM, depends on your case.
I have a requirement to report the number of people who have more than one record in the dataset for my SSRS report and I can't quite get how to filter on the grouping.
So if the dataset results are:
ID PersonID FileID
1 1234 abc
2 7890 ade
3 5647 aer
4 1234 xyz
I would like to report 1. There is one person who has more than 1 record.
Is there an expression or something I can use to do this?
Thank you.
You can use LookupSet and CountDistinct function to get the required count, however you will need the textbox used to show the calculation be in a scope.
If you want to show the number of persons with more than one record as a total in your table use this expression:
=CountDistinct(
IIF(
LookupSet(
Fields!PersonID.Value,Fields!PersonID.Value,
Fields!ID.Value,"DataSetName"
).Length>1,Fields!PersonID.Value,Nothing)
)
Set it outside any group scope:
However if you want to show the number of persons with more than one record outside your tablix in a textbox, you can add an additional tablix and delete the necessary rows and columns to leave only one textbox then set the dataset property to the dataset name you are using and use the same expression.
It should produce:
Note my dataset has more rows to ilustrate the functionality. In the right side there is only one textbox with the count.
Let me know if this helps.
If you want the result to be something like shown below.
Steps:
Create a group on Person ID
Right Click on Group > Add Total > Before
Add a column and put =Count(Fields!PersonID.Value)
If you want to display only Persons having more than one, set the visibility property of the tablix row.
I am trying to find a way to use the Group By functionality to create a table where the numerator of a fraction is grouped both by column and row, and the denominator is grouped only by column.
Here's my existing expression:
=Round(Sum(Fields!Days_In_Step.Value)/CountDistinct(Fields!ID.Value),1, MidpointRounding.AwayFromZero)
When grouped by rows (groupName) and columns (month/year) the numerator (Sum(Fields!Days_In_Step.Value)) gives me good data, but the denominator (CountDistinct(Fields!ID.Value)) is also grouped by row (groupName) and I don't want that.
I have a SQL solution but am trying to do this entire within SSRS expressions, if possible.

Sample Data:
It would look like this. The background is that these groupings are counts of days and the "all" are counts of tickets, so we are trying to see who is sitting on their tickets longer.
Here is a mock-up including a sample data set using a pivot table:
Edit 2
Here is a full sample data set:
https://docs.google.com/spreadsheets/d/1rYPMcrLNB-FZN64Fn2-y3FtnM2iQo2VMH7YTdfiVnKM/edit?usp=sharing
I need to group on month as well as year, and I do not want to see "Exclude" in the group rows, however they cannot be filtered out of the tablix without being removed from the overall population, which is required for the denominator.
Your problem is caused by the scoping of aggregate functions. When you use aggregate function they run under the scope where it is placed in the tablix by default. In your case Sum() and CountDistinct() functions are running in both row groups (Owner Group) and column group (Month Group).
Fortunately, you can specify the scope that you want your aggregate function computes the aggregation, simply add the group name in the function:
CountDistinct(Fields!ID.Value,"MonthGroup")
The whole expression is like this:
=Round(Sum(Fields!Days_In_Step.Value)/
CountDistinct(Fields!ID.Value, "MonthGroup"),1, MidpointRounding.AwayFromZero)
Replace "MonthGroup" by the actual name of your group in columns
group.
This is result using the sample data you provided:
I've used this expression to show you how it is produced:
=Sum(Fields!Days.Value) & "/"
& CountDistinct(Fields!Ticket.Value,"MonthGroup") & "=" &
Sum(Fields!Days.Value)/CountDistinct(Fields!Ticket.Value,"MonthGroup")
Note my column group is named MonthGroup.
UPDATE: Scoping multiple groups in CountDistinct function.
Firstly I am not filtering the dataset, I prefer hide the Exclude rows using the below expression in the Hidden property of the Row Visibility window:
=IIF(Fields!Group.Value="Exclude" OR Fields!Group.Value="-1",true,false)
To count distinct id grouping by Month and Year but not by Group you can create a child group below Month group as you can see below:
My group is called Group2 and I used this expression in the Group on textbox.
=Fields!End_Month.Value & "-" & Fields!End_Year.Value
It will create a group per every Month-Year combination. When you create the group it will be added as a column group so you will have to delete the row so you will be prompted if you want to delete the group and row or delete the row only. Delete only the row leaving the group.
Now the expression you have to use is
=Round(Sum(Fields!Days.Value)/CountDistinct(Fields!ID.Value, "Group2"),1,MidpointRounding.AwayFromZero)
Replace Group2 by the name of the created group in your case.
This is the whole recreation of your scenario:
Let me know if this helps.
I have a Dataset1 which has all records.
I have Dataset2 and Dataset3 for Dropdown filteration.
Dataset1 has a query as follows : select * from vw_shoppinghistory where storename =#storename and city = #city
Dataset2 has a query as follows : Select Distinct StoreName from vw_shoppinghistory
Dataset3 has a query as follows : Select distinct city from vw_shoppinghistory where storename = #storename
On selecting store and then the city should pull the records.
I am facing an error as
" When report contains multiple datasets, field references outside of a data region must be contained within aggregate functions which specify a dataset scope "
You are referencing a field in a dataset on a control that doesn't count as a data region (data regions being things like charts, tables, lists, etc). Most commonly you'll see this on textboxes.
To fix this, you need to do 2 things:
Use an aggregate expression. You can't reference a field outside of a data region without performing aggregation. You can use functions like SUM, FIRST, MIN, MAX, etc.
Specify a dataset when referencing a field. For example, your code that's causing this error is going to look something like this:
=Sum(Fields!city.Value)
What you'll need to do is specify the dataset the field comes from, like:
=Sum(Fields!City.Value, "Dataset1")
I have a column name 'APPs % of total' and it requires two different data sets to be populated .This doesn't seem to work. Any tips will be appreciated. Thanks
=(Fields!AppQty.Value/Fields!AppQty.Value,"second dataset")
The problem is: how does SSRS know which row to pull from the second dataset to get the field? So you have to use aggregation or lookups:
Method 1: Simply aggregate at the current level
There's usually no need for a secondary dataset just for your sums. You can aggregate at the group level within the current dataset by using the following formula:
=Fields!AppQty.Value / SUM(Fields!AppQty.Value, "table1_Group1")
where table1_Group1 is the group where the data is summarised.
Method 2: Aggregate the entire dataset
Aggregate at the dataset level for the either the current dataset or a secondary one:
=Fields!AppQty.Value / SUM(Fields!AppQty.Value, "SomeDataset")
Method 3: Lookup the value from another dataset
You'll need a dataset that sums the values at a group level. You usually achieve this result using method 1 and grouping, but here for completeness. So, let's say you are grouping by DepartmentId, you would have a dataset that aggregates like so:
SELECT DepartmentId, SUM(AppQty) AS AppQty
FROM MyTable
GROUP BY DepartmentId
Then lookup the appropriate value for the department from the current row (in the current table's dataset):
=Fields!AppQty.Value / Lookup(Fields!DepartmentId.Value, Fields!DepartmentId.Value, Fields!AppQty.Value, "SummaryDataset")
So the Lookup matches the DepartmentId from this dataset with the DepartmentId in the SummaryDataset and returns the AppQty value.
