I am trying to perform an aggregation on a calculated Field in SSRS and am getting the following error:
[rsAggregateReportItemInBody] The Value expression for the textrun 'Textbox43.Paragraphs[0].TextRuns[0]' uses an aggregate function on a report item. Aggregate functions can be used only on report items contained in page headers and footers
This is the formula I tried to use:
=Sum(ReportItems!PlanPurchPrice.Value, "Select_UCPUtilization")
In this Case PlanPurcPrice is also an Expression:
=First(Fields!PawPlanPurchPrice.Value, "Select_UCPUtilization")
Any suggestions on this would be greatly appreciated.
SSRS 2008 does not support the functionality you are looking for unless the report item is located in the header or footer (as is stated in the error message). I would, instead, propose two alternate solutions:
First Option
Place the calculation in your query (if possible) at which point you can then reference the field and the aggregate will work as desired.
Second Option
You essentially want to create the aggregate you're looking to return elsewhere in the report where it is directly connected to the Select_UCPUtilization scope, then reference the aggregated value elsewhere. Follow these steps:
Within the same scope as report item PlanPurchPrice, calculate a sum of the PlanPurchPrice. Name the textbox containing the aggregate something meaningful (e.g., Sum_PlanPurchPrice).
Reference that textbox directly wherever you were trying to use the ReportItems sum before (i.e., =ReportItems!Sum_PlanPurchPrice.Value)
Hide the workaround. Place the aggregate you created in an additional column or row attached to the Select_UCPUtilization scope. Turn the text white, turn off growth and shrinkage, and make the row very tiny (a pixel or two high).
Using the second option, the report item does exist (and is visible, which is important) on the report and contains the sum you are looking to return elsewhere.
Hope this helps. if this doesn't make sense, please reply via comment and I'll help you to the best of my ability.

am very new to jasper report
also I have tried looking at videos but can not seem to get this one concept
basically there is this main query which i have
select * from table
which is populated in the details area
however i want a second query
select count(*) from table where name = "tim"
and put the count on the footer
can this be done using jasper
any tutorial to this concept or guidance would be helpful
to sum up the details area should show all the data where as the footer should only show counts of a few things.
You can only have one DataSet (therefore query) for the report. In your case this is your main report select * from table, which seems to be working well.
You have two options for adding the information you want:
(and I would say the better option) is to add a variable $V{tim_count} which is configured as:
initial value 0
expression value "tim".equals($F{name}) ? 1 : 0"
calculation function sum
there are multiple ways to increment this variable, so I'll leave that with you. In the footer you would then add a text field with the $V{tim_count} variable as it's contents.
You can read about variables here https://community.jaspersoft.com/wiki/variables
You can add an object that has it's own DataSet:
Table
List
Subreport
You would then be able to add your query to that object and display it appropriately. As you can see, displaying a COUNT is not really the most appropriate way to do this.
Note - I don't suggest this way
Looking for some advice related to data grouping and printing in Crystal Reports.
I'm working with an order confirmation form. Ideally I would create separate report pages based on a specific field value change for the 'warehouse' field. So, if any given line on an order comes from warehouse A, it prints together. Then we'd get a page break, and we'd see the form repeat for any lines coming from warehouse B.
I've inserted a new group for "warehouse" and configured the group as 'New Page Before.' But when I attempt to print I'm getting an error related to "There must be a group that matches this field". So there must be some pre-existing grouping that I'm not considering. I'm hopeful I can figure this out.
I am interested to get thoughts on overall design, and if the grouping approach I am trying to take is even the correct one.
Somewhere in your report you probably have a formula such as:
Sum({some_value}, {some_field})
where the {some_field} used to be -- but is no longer -- grouped upon.
Fix that expression to set the desired aggregation level (the 2nd argument) to a field you are actually grouping on.
In my main report I get a (small) list of string values from the data base. I then want to use this list for selecting records in a subreport, along with other input parameters:
The user shall be able to select records based on a range of begin and end date -- this is easy using an input parameter of type java.util.Date with "Is For Prompting" set to true. Another criteria shall be one or more items from a list showing values from a data base field. I could define the list in the report template, but then I'd have hard-coded strings (filled from the data base, but at definition time only).
Now the dilemma is: If I define the input parameters in the main report, I cannot get the values for the list beforehand; if I define them in the subreport, I get no prompt at all, so there's no way to set any of them.
So the report requires values for start and end date, and a list of string values to select from (multiple itmes can be selected). This list shall be built from values from the data base. In the subreport all these values shall be joined into a filter for the records. A user shall be able to define the dates and select items from the list manually before executing the report.
Is there a way to achieve this?
After some more hours of trial & error, and some more research, of course, I found that the keyword is "Query-based Input Controls". This documentation describes their creation on the JasperReports Server. Such input controls can be edited in Jaspersoft Studio as well, however, they actually work on the server only. Anyway, this is the solution to my problem.
I have a master report (using iReport 5.0.4) with a subreport that uses grouping by a field called "Group Number" (sorry, but that is the actual column name).
My report works fine when there are more than one group, but it generates each group result scrolling down the page vertically.
I would like to be able to have each group go across vertically, but when I tried using columns, it simply forces each group's data into columns, and not the entire group 1, followed by group 2 in the next column, etc.
There can be up to 8 groups, so I was hoping not to have to create 8 individual sub-subreports with a "print when" expression to show/hide them.
Can anyone tell me if this should be possible?
Thanks,
Mitch
I think making subreports is the easiest and obvious way. But if you want to make it in other way, I can only suggest to use scriptlet, and form dataset manually (Transpose it).
Another suggestion is when you generating report directly from database (i.e. passing connection into jasper) you can modify query and transpose the data (PIVOT table).
Anyway provide more info about your case. I will try to help you.
what is the equivalant command like in vb for EOF(), MoveNext, Moveprevious commands in crystal reports
There are no equivalent answers in Crystal Reports, at least not in the versions I have used. Crystal Reports more or less simply dumps the data out into the report.
That said, if you are in a detail row, and you want to find out what the next value of a field will be, you can use:
next({YourColumn})
You can also find out the previous column value by using this:
previous({YourColumn})
Keep in mind that Next() won't work on the last record, and Previous() won't work on the first record.
I'll have to double-check, but I believe there is an OnLastRecord function that returns TRUE if you are on the last record.
First, welcome to SO!
Second, you sound new to Crystal Report's purpose is to display data, not perform the kind of calculations you're talking about. CR usually goes record-by-record through the data, displaying (or suppressing) each record, and adding group headers & footers.
To answer your question, LittleBobbyTables does give a few good pointers. To see the entire list of functions available to you, there is a list in the Formula Editor (see pic below). Press F1 for detailed descriptions of each command.
You can also:
Create a "Running Total Formula" that will evaluate each record and give a calculation in the group footer.
Do the calculations outside of Crystal Reports and only feed the end result in (perhaps with an unlinked join to your primary table).
The most complex option is to make a subreport that does the calculation and feeds the result back to the main report
Can you give us some more details about what you're trying to do?
