SSRS Grouping on a field, even when there are duplicates - reporting-services

I have a report in Reporting Services and there is a group that is based around a field value. I want the group to repeat itself on the report as many times as there are rows with that field. The problem is that using Field!field.Value seems to only pull distinct values. Since my dataset has rows that have duplicate values, they are not all showing.
When I declare my parent group, is there a way to tell it to group on every row in the parent group, not just the distinct rows?
Alternatively, is there a list of other options I can use other than just .Value on my field?

What about using the RowNumber function (not adding it into the dataset) as an expression to group on?
I don't have a report in front of me right now, but I think that might work.

Is there a second field that you can use a "dummy" (aka tie breaker, key etc), to include in the grouping to make it unique?
This is how I'd do it.
Edit: after comment.
Can you add a calculated field to the dataset, such as Rownumber to act as one?
Edit 2: I mean in SSRS itself: "Calculated field"

In SSRS, how do I compare a value of a parent report item with report items in a child group?

I am using SSRS 2008. I have 3 different groups above my report details that are calculated sums. I am trying to color the limit red if any of the invoice sums(A) in a child group is above the limit(B).
I am currently using this expression, but it is only looking at the first or last invoice amount. The limit report item is in a parent group just above the invoice's group.
=IIF(ReportItems!Invoice_DueDate.Value>ReportItems!Limit.Value,"Red","Black")
My Solution: I decided to use SQL to get the sum of the invoice amount grouped by due date. I then called that field in the parent group.
If I understand your question correctly, then I think you can use
=IIF(MAX(ReportItems!Invoice_DueDate.Value) > ReportItems!Limit.Value,"Red","Black")
You need some sort of aggregate function, such as MAX() to tell SSRS what the scope and operation of what should be done. (For example if you wanted to make sure the total didn't exceed the limit, you would use SUM(...)
You can reference parent groups from a child group using aggregate expressions specifying the parent group Scope.
For example, say we have some simple data:
And a simple table based on this, with a group based on grp.
Here the BackgroundColor property for the value textbox in the detail row is set as:
=IIf(Fields!value.Value > Min(Fields!limit.Value, "Group1")
, "Red"
, Nothing)
This checks all rows in the parent group of the current row, not just the current row. This works as expected:
Without knowing your data it's impossible to say if this will work in your case, but hopefully it gives you something to consider.
Edit after comments
OK, based on further comments it seems like you need aggregate on aggregate functionality.
This is available via SSRS expressions in 2008R2 and above only, so this won't help in your case.
For older versions, your best option might be to add an extra field to your Dataset that supplies the maximum Invoice value for each group, and then you can use this value without issues in the parent group.
There are some workarounds around that suggest using custom code to do this, such as this post, but I've never used this suggested solution and would only even consider it if you don't have any control over the report Dataset.

SSRS set last row as default value for multi-value parameter

I guess that's easy... I have a multi-value parameter that got the list of values from a query. I would like to select as default value the last row.
Can I achieve this using a expression? I would like to avoid creating a second query just to get the last value from the previous query...
In the default parameter expression you can't refer to the field of the dataset, so you can't write something like Last(Field!MyVar.Value, "DataSet1"), as a workaround you can order your dataset to retrive last row as first and use "Get values from a query" which choses first row, if you can't do this then replicate your dataset in the only one solution.
I am working with SSRS 2012 and I was using a multi select option on my report so when I chose the "Get Values from a query" I got all of the values as the default.
I did find a solution. In my report I needed the default name of the town to be the first one so I created another set with the name of the column and a calculated measure that said "[DimTahanot].[Tahana Name].&[אילת]" and filtered it by the same one. (Please ignore the different language). Although hard coded it was good for this report. You could create another hidden parameter for this set if you need it to be the first one by amount or any other parameters that should effect this value, using the filter as a parameter.
Hope this helps.

Get Row Count in SSRS Report Builder

I have built a report using Report Builder 3.0 (that uses SQL Server 2008 R2). Now i wish to now how many records are being fetched from database to the report?
This is possible either by count function in SSRS or by using RANK/ROW_NUMBER function in SQL Query and assigning that as field to the report (RANK/ROW_NUMBER would give us rank to each row and navigating to last page in report would help me getting the total row count).
I tried count function but that counts on some field in the report. For instance = Count(Field!FieldName.value, "DataSetName") Problem in this approach: "FieldName" is not unique in the report and hence the counts get repetitive
Second option: Added Rank/Row_Number but they too use the same kind of fieldName and hence here too the counts get duplicated.
Main Problem: There is no field in my query that is unique (and hence i tried ROW_NUMBER())
How can i find the total row count or rank (for each row) in SSRS 2008?
Use the CountRows function. For example
=CountRows("MyDataset")
will give you the number of rows in MyDataSet.
As someone else mentioned above, I couldn't get CountRows("DatasetName") to work in the header until I wrapped it thusly:CSTR(CountRows("DatasetName")).
In the Tablix control's properties, there's a property name called NoRowsMessage put your message here when no row is returned.
you can't put aggregation values into the detail wihtout grouping.
Solution is below:
=Count(Fields!rn.Value)
I use it inside the column/header row.
I found a workaround for this. First create a data column with the value always set to 1. This will provide a value of one for each row of data.
Query Column
, 1 AS Unit
Use the "RunningValue" function into your report as shown below.
=RunningValue(Fields!Unit.Value,Sum,"DataSet")
This will also work as a 'running sum' if that's something you're looking for.

Make Tablix Column group show when filter returns no rows - SSRS

I am working on some SSRS reports and am running into an issue where Tablix Column groups drop from the table when the filter returns no rows.
Is there any way to make this column appear but with empty cells? I have another tablix grouping adjacent with the same columns and I want the columns to all line up on the multiple tablix.
Am I just missing a simple option?
Maybe add a
UNION SELECT '', n ..., '';
clause to your report query? It's ugly but should work. If you go this route, add a comment for your colleagues (or your future self) that will have to maintain the report.
I have not been able to make these columns appear on the SSRS report end. Specifically I am getting data by month for display. My solution is make a "Result" table on the SQL side with $0 for every combination, then update this table.
Frustrating, but it works.

Exclude hidden table row from total

I've created a table with a group filter so some values stay hidden.
However, the row that shows the sum() of the above values, still counts the filtered values.
Usually I would apply the filter to the query, but I'm also using this same dataset in other tables on the same report so that's not an option.
Am I missing something here, or is this a flaw in MS Reporting Services?
This appears to be a "feature" of SSRS, apparently because it calculates values in table headers and footers before rendering the detail section of a data table.
One way around this would be to add a derived Boolean column to your dataset (assuming your data source is SQL Server, using a CASE statement or similar) showing whether the row should be excluded from the table where the filter is required.
You can then change your table filter to check the indicator, and use a expression to carry out a conditional sum to aggregate the correct total. Something like
=SUM(Iif(Fields!ExcludeRow.Value = True,0,Fields!ValueToSum.Value))
It's more of a question than answer...
How to resolve this issue if you know whether the row is hidden or not ONLY at the Row Group level?
i.e. if you're filtering on the totals by this Row Group, i.e. you cannot have a field indicating if Row is excluded or not in a dataset.
ex: I have AR Aging report which has totals per months, patients. I need to filter out negative totals per patients (Patient row group), but I have column groups as well - per month, so my dataset cannot be per-patient granularity and therefore, the only place SSRS can decide whether to hide or show the row is on the Row Group level...
I had the same issue but I had too many column totals where to enter the Iif().
I resolved it by removing the filter from the group and putting the filter into the Tablix Properties dialog box (Select Tablix, Right-click the top left corner grey box and choose Tablixc Properties).
