SSRS IIF Syntax with Multiple Datasets - reporting-services

I have a report with 2 data sets and would like to perform a SUM operation in a textbox expression. The problem arises when I want to perform an IIF in the sum since I only want a particular category of values summed.
I would like to get a sum of all the "Good" ranking values from the dsRetrieveCustomerAssetScores dataset. Please note there is more than one data set in the report, so I need to specify the scope when using the aggregate function. Below is the code I've tried (along with other permutations).
=Sum(iif(Fields!ranking.Value,"Good",1,0), "dsRetrieveCustomerAssetScores")
Any ideas?

You may have more than one dataset in your report, but I don't think it's possible to have more than one dataset per tablix. (Subreports within the tablix may be bound to a different dataset, but anywhere within the subreport will only be accessing that other dataset.)
The scope specified within aggregation formulas is normally related to groups within the tablix, not the datasources.
So, the code:
=Sum(iif(Fields!ranking.Value,"Good",1,0))
- should work within your tablix, as long as that tablix is accessing the dsRetrieveCustomerAssetScores dataset.

Access - Modular reusable subreport

I would like to create a report which I can use as a sub-report multiple times on the same parent report. However, each occurrence of the subreport should have different values.
For instance, there is a table called DailyReport.
Records in this table contain:
Date, member, team, description
The sub reports should be for each team within a certain date range. However, the date range per subreport/team will not be the same.
So, if the date range for all teams was consistent, then I could create a single subreport, and do some Ordering on the resulting records to separate things out into teams.
However, with inconsistent date ranges, I can't utilize a single query, so the most straight forward solution I see is to create separate subreports and queries for each range of each team.
The problem with this solution is that if I decide to change the format of the subreports I must do so in each specific subreport--a lot of duplicate work.
I would like to create a generic query and subreport. The query and sub report would call VB functions which would return the relevant value.
This means my parent report has the same generic report on it multiple times. As each subreport is rendered, I would like to increment a value behind the scenes so that the functions which the generic query and subreport call know to return a different value.
However, it seems that's not how things work in Access. The subreports on a report are not rendered linearly. A subreport is created, and then "stamped" onto a report where ever required. This means that all of my generic subreports have the same data.
How can I define a generic report and query? Then plug in different values into the report and query while the report is being reused multiple times on the same parent report.
You need to look into the LinkMasterFields and LinkChildFields property of reports. They are designed for exactly this purpose -- to filter a subreport based on current data in the main report, without needing any code or even queries.
You are correct that LMF/LCF do not work on date ranges, only values. So use LMF/LCF for the team filter.
For the date range filtering, you can use an unbound form that launches the report as two parameters defined in the base query. Create frmLaunch, and add two text boxes minDate and maxDate. Set their Format property to Short Date so Access with interpret them correctly and provide the date pickers. Now modify the base query, adding two Date/Time parameters [Forms]![frmLaunch]![minDate] and [Forms]![frmLaunch]![maxDate]. Now, find your date field and set its criterion to Between [Forms]![frmLaunch]![minDate] and [Forms]![frmLaunch]![maxDate]. Add a button to frmLaunch that runs the code DoCmd.OpenReport "YourReportName", acViewPreview.
So, the goal was to make it possible to re-use the same sub-report multiple times on the same parent report, with full flexibility on how the subreport retrieves data.
I placed multiple instances of the same subreport on a parent report. On the subreports Open event I placed a line like
Me.Report.RecordSource = "SELECT * FROM someTable WHERE " & getCriteria()
nextCriteria()
Maybe its possible to pass a value that identifies which instance of the subreport is opening to the getCriteria function. Probably like a getCriteria(Me.Report.Name). But in this case I kept track of how many subreports had been produced in vb.
Unfortunately, if your subreport has controls which have a data source which is a vb function, all reports will show the same value for that control. To get around this I added something like getSomeValue() & "As [Some Value]" into the SELECT of the SQL statement above. Don't forget to add single quotes or hashes around getSomeValue() if you are passing a String or date.
That's basically it, it's a pain. But I couldn't find a more elegant way to do it.
Edit:
One major caveat I experience with doing this, is that although the print preview works correctly, when actually printing or exporting to PDF, some subreports would not be included. Maybe there is something else causing this...

SSRS Report - Subgroup Totals

I have an SSRS report that is currently pulling a single dataset. This dataset contains records of inventory we have. Each record is a separate asset.
I want my report to group by a certain field, and then subgroup by certain criteria that are determined with a couple different fields. Basically there is one parent group, and three adjacent subgroups. My grouping functionality is working correctly, however I am finding it difficult to add totals to each of the adjacent subgroups. When I add a total, it is totaling the specific field within the scope of the entire dataset, instead of limiting the total to just that subgroup.
How can I add totals per field within subgroup?
EDIT: Added sample data and explanation:
You can ignore the function code field, that is what I am using to group on the parent group.
asset number,description,first year,acquisition cost,function code
190,random asset,2008,5000,100
193,random asset45,2008,56000,100
197,random asset26,2014,3000,100
191,random asset27,2014,7000,100
192,random asset36,2013,15000,100
I can't seem to attach screenshots, so here goes..
In the report you can see three subgroups; Assets, AssetAdditions, AssetDeletions. In the tablix, you can see where these groups are positioned. You can also see a row directly beneath the group that is supposed to total the subgroup at the end. However, for some reason the scope is only taking into account the entire dataset. I have tried to modify the expression in the Sum function [Sum(acq_cost), "Assets"], adding in the scope parameter but then it does not allow me to even run the report. It yells at me saying that "Assets" is an invalid scope.
The easiest way I have done this in 2012 VS is to have it return as part of the data set and have it sum up the value.
For instance if you have a quantity for inventory, and you have a subset where you only want the total quantity for that set, you add another column to your dataset called TotalSetQuantity and the subtotal field will have the expression =SUM(Fields!TotalSetQuantity.Value) rather than =SUM(Fields!Quantity.Value).
You can try iif statements within your report like =sum(iif(Fields!ColA.Value=1,Fields!Quantity.Value,0) but I had some troubles getting that to work.
Hope that helps, I ran into this issue this past week and the first option worked like a charm for me.

SSRS first function automatically added

I'm using SSRS in SQL Server 2008 with Report Builder 3.0 and was wondering, when I add a field on my report from a dataset, why does it automatically add the First() function to it ?
Instead of adding [Field] in a text box, it adds =First(Fields!Field, "Dataset")
Datasets are assumed to always be multiple rows (even though that may not always be the case). So when you drag a field to a report object that isn't meant for multiple rows - such as a textbox - SSRS needs to use an aggregate function of some sort, so that if multiple rows do come back from the dataset, the report doesn't break (since that textbox isn't made to automatically repeat itself for every row).
FIRST is chosen simply because it's least destructive; it could just as easily be SUM, AVG, or any other aggregate function.

Reporting services, sum all rows of a column

I'm using reporting services 2005, I have a report with a table(table1) which displays data from an sql database.
A column on the table displays numbers. I want the total of all rows for that column, on a textbox(textbox3)
of another table(lets call it table2).
I tried placing this on a table2 textbox: =Sum(ReportItems!textbox1.Value)
texbox1 is the one from the table1. But when going to the Preview tab i get:
Error 2 [rsAggregateReportItemInBody] The Value expression for the textbox 'textbox3' uses an aggregate function on a report item. Aggregate functions can be used only on report items contained in page headers and footers.
How can I solve this?
Thanks.
You've got a couple of options.
The first is to use an expression similar to the following in the Textbox:
=Sum(Fields!value.Value, "Values")
Where Values is the name of the DataSet you want to aggregate.
Here you're creating an aggregate expression and specifying the scope where it executes, in this case a DataSet, i.e. aggregate all values in the DataSet.
As you can see from the error you're getting you can reference a report item with an aggregate, but if you're displaying the aggregate in the table header or footer you can reference that Textbox.
Here's a simple report showing both methods:
Hopefully you can adapt one method to your report.

ssrs two datasets used in a list for two matrixs

In SSRS 2005 I have a report with two matrix with two data sets. The report was running fine based when ran on different parameters.
Now I have been asked to modify the report and place another option in the parameter for "All" this will retrieve the results of all parameters and once extracted to Excel it will create different sheets in Excel for based on each parameters results.
For the above purpose I am using a list so each parameter result would be on one page but the problem is when I add the two matrix in the list the second matrix only retrieve values of first data set as the column names are similar. I can provide the second matrix value of second dataset with First(Fields!Site.Value,"Second DataSet") but it obviously picks up only the first value from the second dataset.
I was wondering if there is anyway I can use two datasets in a list and the second dataset picks up all the values and not just only the first value.
Or is there a better way to achieve the above in SSRS.
1) remove First from this expression : First(Fields!Site.Value,"Second DataSet")
2) your expression should be only =Fields!Site.Value. No need to provide dataset name"Second DataSet".
