Im building a report that's using two datasets. when I preview I find these types of errors...
Error 19 [rsFieldReferenceAmbiguous] The Value expression for the text box ‘Textbox3’ refers directly to the field ‘PerZipCode’ without specifying a dataset aggregate. When the report contains multiple datasets, field references outside of a data region must be contained within aggregate functions which specify a dataset scope.
What aggregate function is needed and where is there an option to set this?
If you are adding multiple datasets to a report, the above may not fix your problem. You may just get the following error when you aggregate it:
[rsMissingAggregateScope] The Value expression for the text box ‘textbox6’ uses an aggregate expression without a scope. A scope is required for all aggregates used outside of a data region unless the report contains exactly one dataset.
What you may need is something like :
First(Fields!MyField.Value, "DATASETNAME")
Which you can get by using the Expression Builder, rather than the drag and drop of fields from the dataset.
Min or Max or Avg etc: most of these
The aggregate is needed to reduce the other DataSet to one value (max of values etc) because you are using something not in the local scope (eg the DataSet bound to the Data Region). There is no way to match rows in the other DataSet with the local scope DataSet.
If your text box is standalone (not in a Data region), the same applies: the aggregate is needed to tell SSRS which row to take (Max etc) or what calculation to do on the dataset (Avg etc)
To use multiple dataset value on SSRS report we need to use below code.
First(Fields!MyField.Value, "Datasetname").
If by typing this you are still getting the same problem then right click on textbox & select expressions then in expressions click on Dataset. Select you dataset & then double click on required column. After this click on ok.
If you have multiple controls then follow the same for all of them & verify the same by executing the report.
If you already have an aggregate and are having this error, it is probably because the fields of the report aren't up to date with the dataset(s). You can fix the issue by refreshing the fields of the report.
To populate the field collection, use the Refresh Fields button on the Dataset Properties dialog box.
The field collection does not appear in the Report Data pane until the Dataset Properties dialog box closes.
To refresh the fields for a specific dataset
In the Report Data pane, right-click the dataset, and then click Dataset Properties.
Note :
If the Report Data pane is not visible, on the View menu, click Report Data. If the pane opens as a floating window, you can dock it. For more information, see How to: Dock the Report Data Pane.
In the Query pane, type the query. Alternatively, you can use the Import button to import your query from another .rdl file.
Click Refresh Fields.
Click OK.
In the Report Data pane, expand the dataset node to view the currently defined field collection.

I have a SSRS report that takes a parameter and executes a stored procedure to generate a report with it.
the parameter is a values from a table that I have user select from a dropdown
let's say 15 options that are passed as parameters to each execution.
AAAA
AAAB
AAAC
...etc
is there any way I can setup the report so it will execute with each parameter and generate a report?
the issue is that now the user has to manually select 1st parameter, generate the report and then export the file result to excel.
what I want to do is a way for the user to select multiple parameters and export just one file containing all of them (the stored procedure can't take more parameters because of the way is coded depends on receiving one parameter only)
so it would have to schedule multiple executions of the stored procedure to create the report and then export this. is this possible? (as a note, the amount of parameters will change frequently so I need to give the option of selecting multiples from a list that is populated from a query to database)
and to clarify, the Stored Procedure needs to take only one parameter, this is not to be solved by sending multiple parameters to operate by using a splitter or similar, as the parameter received by the SP is used in calculations depending of order, (to not go into detail with the SP, just need to take one parameter per execution)
As you already have a report that handles a single option then you can do this easily using sub reports. Don't worry about the length of this answer it actually quite simple.
I would make a copy of the existing report to be safe....
Change the existing report to only accept a single parameter value if if doesn't already. Save this report, this will be your sub-report so let's say it's called mySubReport
Next create a new blank report.
Add a dataset (called say dsParameterList) that will give you the list of options you want the user to choose from (I guess this will be the same as your current report?). For example if it was a list of companies it might look something like SELECT CompanyID, CompanyName FROM myCompanyTable
Next add a parameter called say #options, make sure it is set to be multi-value and set the available values to use a query and point this to dsParameterList. Set the value and label fields as required.
Now create another dataset called dsLoop for example. This dataset will contain a list of selected parameter values. Using the company example from earlier the dataset query might look something like this. SELECT CompanyID, CompanyName FROM myCompanyTable WHERE CompanyID IN (#options)
Next add a table to your report and remove columns so that only 1 remains. Set the dataset property of the table/tablix to dsLoop. This means we will generate 1 row for every selected parameter value.
In the detail row right click in remaining textbox and choose 'Insert Subreport'. Now right-click the subreport placeholder and set the properties to point to the report we saved earlier (mySubReport in this example).
Whilst still in the sub report properties, click the parameters tab and add a new entry, choose the parameter in the left column and set the value in the right column to be the value from dsLoop that you want to pass to the subreport. In our company example this would probably be [CompanyID]
That's it. You run the report and choose from the parameter list, when you click View Report the dsLoop query runs and gives us a list of just those selected Companies, the report body is generated with a row for every row in the dsLoop dataset which in turn runs the subreport with a different parameter passed in each time.
Optionally You can right-click the rowgroup under the main design window and set the 'pagename' property to a value. In the Company example this might be =Fields!CompanyName.Value. When the report is exported to Excel each sheet in the workbook will be named with the name of Company
I have a query that returns relevant data about inspectors and how long it takes them to respond to issues. The only parameters are a BeginDate and EndDate so for any given date range there could be anywhere from 0 to 100 inspectors.
I am using only one dataset and it contains an "Inspector" field that I'm hoping can be used as a filter to create as many tables as there are inspectors.
I know you can set filters on tables but from my (limited) SSRS knowledge, you must already have the tables created and the filters are typically hard-coded. What I need, is some way for the report to see how many Inspectors there are in the dataset and group those records into their own tables, repeating the same one created tablix over and over as needed.
This is being done strictly in SSRS 2012, not using a ReportViewer where back-end code could help me out unfortunately...
I don't have any code examples to provide, like I said I know you can do filtering but I am at a loss when it comes to doing something like this dynamically based on data... Sorry.
Depending on the report design you could either...
Single report with grouping
1. Create a single tablix.
2. Create a row group by Inspector and then add whatever fields you need to the details section.
3. You can optionally set page breaks between instances of your Inspector rowgroup from the rowgroup properties.
Sub report method
1. Create a subreport that accepts a parameter (InspectorID for example).
2. In the subreport filter the dataset using the parameter passed in so it only return data for a single inspector.
3. Add whatever controls you need to the report to handle a single Inspector
4. Create a main report
5. Add a dataset that gives you a simple distinct list of Inspectors, this will be used to pass parameters to the subreport.
Lets assume it just contains a list of InspectorIDs.
6. Add a list control to the report and set it's dataset property to the dataset that contains your list of InspectorIDs
7. Right-click in the list control's 'cell' and insert a subreport.
8. Set the subreport property to the subreport you created earlier and set that parmameter IsnpectorID to your InpsectorID field.
This will produce a subreport for each instance of inspector it finds.
Sorry about the format of this answer, in a rush!
I need a row value in my SSRS report that is a calculated one based on a couple of fields that are already being used in the report. I want it to display in the textbox named 'textboxPercentageValue'. In semi-plain English, the expression/formula is:
If the value of the "Week" field is "WK1", display the value of the Variance field divided by the value of the Price field; otherwise, just display the value from the Variance field.
In VB script gobbledygook, the expression/formula I've add to textboxPercentageValue's Value propert is:
=IIF((Fields!Week.Value="WK1"), Fields!Variance.Value / Fields!Price.Value, Fields!Variance.Value)
Yet, when I try to upload the .rdl file to SQL Server Reporting Services, I get:
"The Value expression for the text box ‘textboxPercentageValue’ refers directly to the field ‘Week’ without specifying a dataset aggregate. When the report contains multiple datasets, field references outside of a data region must be contained within aggregate functions which specify a dataset scope.

So what do I need to do to make this expression/formula unambiguous to SQL Server Reporting Services or the VBScript parser or "whoever" is complaining about it?
It sounds like your Textbox has been added to an area of the report that isn't a "data region" (e.g. a table or list). A data region will have a reference to a particular report dataset as one of it's properties, so Reporting Services knows all field references inside that data region refer to that dataset. What this error is trying to say (in a rather verbose way) is:
if you reference a field outside of a data region, that reference needs to be inside an aggregate expression such as Sum() - this is because the dataset may contain multiple rows for the field but outside of a data region a textbox can only display a single value.
this aggregate expression must also include a reference to the report dataset that the field is coming from
So if field "WK1" was from dataset "MyDataset1", the expression to reference that field would look like:
=Sum(Fields!WK1, "MyDataset1")

This is an interesting problem, because if you have ONLY 1 data set in your report, you don't need a table, you can directly reference a field that exists in that table.
However, if you have more than 1 data set then you must create a table, which may give you multiple rows. Then you might have to group by this one field, and hide the extra columns and rows. However, you CANNOT display this data in a TEXTBOX, you can however create a rectangle which can hold the table and another textbox. Or display the table directly.
A text box can get knocked out of its context and still appear to be in it. I came by this post looking for the same error message and it was one textbox in a series of several and it had worked just moments before I had readjusted formatting. After getting the info in the first answer, I went back and poked around and found the textbox throwing the error was actually be the list box but appeared to be on the same levels as the others unless I was trying to move or resize the list box. Moving the textbox out and dropping it back in fixed things. As someone coming upto speed on SSRS from a programmer prospective, the insight in the first answer solved a frustration that has come up repeatedly!

I need to add a filter to a Report, that within anotherreport, the filtered results appear in the drilldown report.
For example: An .rdl file displays the first report, in that report a link can be clicked to access another report (.rdl) file. The report that displays after clicking link should be filtered by option selected from the first report(.rdl).
How could this be done? My thought that two datasets in each report could provide the information for the filter, however the filter expression is not valid this way...? I know this may not be the best way to do this.
So creating a drilldown report would be more acceptable. Creating one report and including a dataset with it by setting parameters to be called in the drilldown.
Does there need to be two datasets for each report to do this? I was assuming that the filter expression be written to do this: Field!.name.value AND Field!.name.value, etc to the whatever value I need to compare to or by.
Could this be a shared dataset to do this?
I was able to solve or partially solve this. I created a new report, with a query with the necessary columns that I needed in report 2. The drillthrough report(report 2) is linked from a textbox from a report allowing a user to view the information they need by clicking a link that displays the new report(passing the parameters from report 2 to the new report). If anyone has trouble with this, the simplest way would be to create one report and pass parameters to report two with parameters created from whatever query you want to use that has the values you want as columns in the report.
