ssrs Summing two fields same dataset, different tablix - reporting-services

I am trying to sum two same fields, from two different Tablix's.
Both Tablix's filter for different building names. "Mydata" is the name of my dataset.
=Sum(Fields!TotalFloorArea.Value,"Mydata") +Sum(Fields!TotalFloorArea.Value, "Mydata")
How do I reference the different Tablix?
Many thanks in advance.


There is more than one way to accomplish this. One approach is to use an IIf() as part of each of your SUM() calls. Using the IIf() condition(s) you will be repeating the condition(s) used to filter your two Tablix controls.
Try something like this:
=Sum(IIf(Fields!BuildingName.Value = "BLDG-A",
Fields!TotalFloorArea.Value,
0), "Mydata") +
Sum(IIf( Fields!BuildingName.Value = "BLDG-B",
Fields!TotalFloorArea.Value,
0), "Mydata")
I prefer to use Report Variables for this. Define a couple of report variables totalBuildingA and totalBuidlingB and use the expressions above for the individual variable's expressions:
totalBuildingA
=Sum(IIf(Fields!BuildingName.Value = "BLDG-A",
Fields!TotalFloorArea.Value,
0), "Mydata")
totalBuildingB
=Sum(IIf(Fields!BuildingName.Value = "BLDG-B",
Fields!TotalFloorArea.Value,
0), "Mydata")
Then you can add the two report variables together to get the equivalent result as the first example, (but with code that is a lot more flexibile for combining the SUMs for two or more other Building Names etc):
=Variables!totalBuildingA.Value + Variables!totalBuildingB.Value


I got this to work now. I added a row Outside the group below then added Totals into Rows. Then for grand total I referenced the textboxes for example Reportitems!Textbox22 + Reportitems!Textbox23.
I'm not sure this makes sense. But now working! Just trying to work out the final formulas.


Referring to textboxes can get messy. And there's no direct way to reference sums from other groups or tables. A good option that will work for this is to add calculated fields to your dataset. You can have one for the 1 building value and another for the other 25 buildings. The expression would look something like this:
=IIf(Fields!BuildingName.Value = "BLDG-A", Fields!TotalFloorArea.Value, Nothing)
That way you can sum those calculated fields from anywhere in the report. You don't need to specify the scope in your Sum function, let it use the current scope for the cell like this:
=Sum(Fields!BldgA_TotalFloorArea.Value)

Can I use WHERE clause in an SSRS expression?

I saw the post on WHERE clause in SSRS expression. I am also trying to do a where clause, but in a different way. I need to show ItemDesc when ItemId = 4. I set a parameter so that it will always equal 4 for this cell. Now I just need the matching description field. I cannot hard code it because the description may change one day. Is there a way to associate the two fields?
=IIF(Parameters!ItemID_4.Value = 4, Fields!ItemDesc.Value,"")
I am converting from Crystal Reports to SSRS. This first image is the output from CR. I only need to show that ItemDesc in that top left cell.
This next image is from SSRS. It is not limiting the descriptions. It seems to be doing what my expression is saying. ItemID = 4, so display all ItemDesc values but the two fields are not associated right now. I need it to only show the matching value.
Thank you for your help.

I cannot hard code it because the description may change one day.
You are hard coding the parameter anyway by trying to do it that way. I don't think you need a parameter to achieve the result unless you are restricted from adjusting the dataset query.
If you are using an embedded SQL query for your dataset, I would just put a filter in WHERE clause: WHERE ItemID = 4
Another way if you can't adjust the query is to go to Report Data view > Right click on the dataset for your table, "Dataset Properties" > go to the "Filters" tab and add a filter with these settings: Expression = ItemID, Operator = "=", Value = "4" (or "#ItemID" if you want to keep your parameter).

SSRS - possible to share the same filter definition for a chart and a tablix?

In Excel you have the option of showing a table below your chart that shows the data used in the chart - I am trying to replicate that behavior in SSRS.
Scenario:
I have one dataset from which I want to populate two (Chart + Table) elements (so two charts and two tables). Each Chart + Table combo needs to use the exact same filter, but I don't want to manually define that exact same filter on each object (if I need to change it, I don't want to have to make the change on two entities).
Yes I know there are other ways to accomplish the same end result, such as perform the filter in the SQL, or to instead define two separate datasets, and then apply the filter on the dataset itself (so it will then cascade down to both the Chart and Table).....or in other words, I'm not asking if this is a good idea, I'm asking if it is possible. :)

Closest thing I can think of to what you want is to define the logic of your filter in custom code, and call the custom code in your two filters.
If the logic ever changes, you would only have to change it in one place.
But it's not possible to define the filter on your tablix, for instance, and then in your chart put in some kind of "use the same filter as my tablix" command.

I would add a Calculated Field that checks your criteria and gives a 1 or 0 depending on whether it meets all the criteria or not.
Field Name: MeetCriteria
=IIF(Fields!AGE.Value < 10 and Fields!status.Value = "PAID", 1, 0)
Then you just need to filter on the new calculated column:
Expression: Fields!MeetCriteria.Value
Type: INTEGER
Operator: =
Value: 1
Not quite what you want but much easier than duplicating the criteria everywhere.
For a multi-value Status parameter, you could do something like:
=IIF(Fields!AGE.Value < 10
AND INSTR("|" & Join(Parameters!Status.Value, "|") & "|", "|" & Fields!Status.Value & "|") > 0,
1, 0)

SSRS Filter with a different column from a different dataset

I want to filter my column, let's call it AllStudentID from dataset1 with another column from a different datset.
Dataset1 had many column such as AllStudentID, Class, Time, Location.
Dataset2 has other columns but i'm focused on a similar column called OnCampusID.
I've tried looking into using a filter but since the report itself has the columns from Dataset1, i run into an issue where if I select the column in dataset2, it always gives a First(OnCampusID). And I don't want that.
I looked into IIF() but again, i'm using a column from a different datset plus if let's say that they are NOT equal, I don't want to display anything, instead of putting something there. I know that you have to put a result if true and a result if false.
If I"m thinking of it in terms of SQL statements, it's like having a WHERE clause WHERE AllStudentID=OnCampusID.
I tried running a Parameter but I don't want the select part on the top but rather have the report filtered already.
Am I missing something? I know it has to be simple.
Mind you, the following example above is just an example i made up, not the real thing.

Assuming that each OnCampusID only appears once in Dataset2 then you can do a Lookup expression to filter it:
=IIF(IsNothing(Lookup(Fields!AllStudentID.Value, Fields!OnCampusID.Value, Fields!OnCampusID.Value, "Dataset2")), False, True)
If OnCampusID appears more than once in Dataset2 then do the same thing using LookupSet.
To get the graduate field from Dataset2 just to a Lookup in the Value of the cell, like so:
=Lookup(Fields!AllStudentID.Value, Fields!OnCampusID.Value, Fields!Graduate.Value, "Dataset2")

SSRS expression issue using iif function

I have a data set that is returning two properties, a name and a total units. I am trying to set an iif expression on a data bar where iif(field!Name.Value = "Name", field!Total.Value, 0)
this is not working I get an error of rsFieldReferanceAmbiguous, the fields refers without specifying a dataset aggregate. And the only option that it gives me as an aggregation is First, but I do not want to get the first name, I want the bar to display the total units base on the name field that is in the iif expression.

rsFieldReferenceAmbiguous refers to trying to match something that is not in local scope. Therefore you have to aggregate it. You are probably wanting something like this:
=Sum(IIF(Fields!Name.Value = "Name", Fields!Total.Value, 0))

The function you are trying to use would be better suited to a calculated field in your dataset. Then you can just refer that that field in your report. This allows you to filter the data line by line instead of by groups.
Right-click on the dataset and go to Dataset Properties.
Go to Fields.
Click Add then Calculated Fields.
Enter the name of the field and then the expression here.

Make sure your tablix has the dataset specified under General -> DataSetName on the properties pane. If you have more than one data set on the report you will need to specify which data set your reffering to like so:
(Fields!Name.Value, "NameDataSet")
If your useing tables you may need to ckeck if you have grouping and if so how your grouping your data.

How do i represent an unknown number of columns in SSRS?

I'm working on a rather complex report in Sql Server Reporting Services. My SP returns a dynamic number of columns each of which are dynamically named.
Basically think of a time keeping application. Each column that is dynamic represents a time bucket that time was charged to for that team. If no time was charged to that bucket for the period of time the report covers it doesn't show. Each bucket has its own identifier which i need to be the column headers.
I have an SP that returns this all. It does it by doing a bit of dynamic SQL with an exec statement (ugly i know but I'm on SQL 2000 so a PIVOT option wouldn't work)
I can have an indefinite number of buckets and any or all might show.
I found this - http://www.codeproject.com/KB/reporting-services/DynamicReport.aspx - which is helpful but in the example he has a finite number of columns and he just hides or shows them according to which ones have values. In my case i have a variable number of columns so somehow i need the report to add columns.
Any thoughts?

As long as you know a maximum number of columns, it's possible to do this after a fashion.
First, name the columns with a result from your query, so you can either pass it in to the query or derive it there. Second, just build out the report as if it had the maximum number of columns, and hide them if they are empty.
For example, I had to build a report that would report monthly sales numbers for up to a year, but the months weren't necessarily starting in January. I passed back the month name in one column, followed by the numbers for my report. On the .rdl, I built out 12 sets of columns, one for each possible month, and just used an expression to hide the column if it were empty. The result is the report appears to expand out to the number of columns needed.
Of course, it's not really dynamic in the sense that it can expand out as far as you need without knowing the upper bound.

This can be done. I did this and it works fine.
You don't have to know the maximum number of columns or show and hide columns in my approach. Use a matrix and modify your sp to return dynamic data to the structure mentioned in this blog post http://sonalimendis.blogspot.com/2011/07/dynamic-column-rdls.html

Build 2 related Datasets, first one for the report content, and the second one for the list of its column labels.
The Dataset of the report content must have a fixed number of columns and name. You can allocate some maximum number of columns.
In this example I have the first 2 columns as fixed, or always visible, and a maximum of 4 columns to be displayed by choice through a multivalued parameter, or depends on the query conditions. And as usual, we may have a total as well. So, it may look like this:
Fixed01, Fixed02, Dyna01, Dyna02, Dyna03, Dyna04, Total
The second Dataset with its values will look like this:
Name Label
---- -----
Dyna01 Label01
Dyna02 Label02
Dyna03 Label03
I have omitted the 4th Label to demonstrate that not all columns are being used by a certain query condition. Remember that both Datasets are meant to be related to the same query.
Now create a parameter named, say, #columns; populate its Available Values and Default Values with the second Dataset.
For each of those 4 dynamic columns, set the column visibility with the following expression:
=IIf(InStr(join(Parameters!columns.Value,","),"Dyna01"),false,true)
And for each of their column header Text Boxes, use the following expression:
=Lookup("Dyna01", Fields!Name.Value, Fields!Label.Value, "dsColumns")
As for the Total, here is the expression for its visibility:
= IIf(InStr(join(Parameters!columns.Value, ","), "Dyna01"), false, true)
AndAlso IIf(InStr(join(Parameters!columns.Value, ","), "Dyna02"), false, true)
AndAlso IIf(InStr(join(Parameters!columns.Value, ","), "Dyna03"), false, true)
AndAlso IIf(InStr(join(Parameters!columns.Value, ","), "Dyna04"), false, true)
And here is for its values:
= IIf(InStr(join(Parameters!columns.Value, ","), "Dyna01"), Fields!C01.Value, 0)
+ IIf(InStr(join(Parameters!columns.Value, ","), "Dyna02"), Fields!C02.Value, 0)
+ IIf(InStr(join(Parameters!columns.Value, ","), "Dyna03"), Fields!C03.Value, 0)
+ IIf(InStr(join(Parameters!columns.Value, ","), "Dyna04"), Fields!C04.Value, 0)
That's all, hope it helps.
Bonus, that second Dataset, dsColumns, can also hold other column attributes, such as: color, width, fonts, etc.

I think the best way to do it is add all the columns in your table and edit the visibility property of it with the help of arguments that you get from your SP..this will solve the purpose of dynamic column but when viewing the report you will get a lot of white-space which you can solve with SSRS - Keep a table the same width when hiding columns dynamically? and your report will be ready

I've had the need to do this in the past and the conclusion I came to is "you can't", however I'm not positive about that. If you find a solution, I'd love to hear about it.
An issue that comes to mind is that you need to define the report using the names of the columns that you're going to get back from the stored proc, and if you don't know those names or how many there are, how can you define the report?
The only idea I had on how to do this is to dynamically create the report definition (.rdl file) via C#, but at the time, I wasn't able to find an MS API for doing so, and I doubt one exists now. I found an open source one, but I didn't pursue that route.
