I am building a report(report server project) using the Data Tools. I have a column Quantity it has a Total.
I need another column that calculate the share(%) of each line in the Quantity comparing to the Total.
The expression would be: Line_1_Share = Quantity_of_line_1/Total.
I tried =[Sum(Total/Quantity)] but it does not even accept as a valid expression.
If you right-click the textboxes that contain your working 'Quantity' and 'Total' values and look at the expressions you will see the correct format.
For exmaple your 'Quantity' expression might be something like
=Fields!Quantity.Value
or if it is in a grouped row it might be
=SUM(Fields!Quantity.Value)
your 'Total' expression might also be
=SUM(Fields!Quantity.Value)
When you use SUM() (or any similar aggregate) then the scope of the expression decides what is included in the sum. The scope can be a single row, a row group or an entire dataset. If you do not specify a scope then the position of the textbox determines the scope.
So, if you have a simple table with no grouping other than the total line and your dataset name is dataset1 then your expression would need to be
=Fields!Quantity.Value / SUM(Fields!Quantity.Value, "dataset1")
The above reads .... "For the current row, take the Quantity and divide is but the sum of all Quantities that are within the entire dataset called dataset1"
If this does not help, post your current report design including and row and/or column groups.
I have a dataset which looks like this
Name Spend
"First Aid" 2
"Healing Arts" 0
"Surgeon" NULL
I then have three separate textboxes which will be filled with the value of the column which matches the name.
Example: show value of spend in textbox if value of name equals First Aid
for this I've made following expression
=Lookup(Fields!skill_name.Value, "First Aid", Fields!skill_spend.Value, "Skills")
My problem is however that I get an error saying that skill_name is missing its dataset, which doesn't make sense to me as it is informed in the end of the expression (skills)
I think you may be misunderstanding the purpose of Lookup and how it is used. The purpose of the Lookup function is akin to a JOIN in SQL in some ways. Basically, you would have two datasets that each have a matching field with the other. In that scenario, the expression would match on the skill_name field and lookup the skill_spend value and the expression would look something like the following.
=Lookup(Fields!skill_name.Value, Fields!skill_name.Value, Fields!skill_spend.Value, "Skills")
As the documentation shows, the first reference to skill_name is the field you are referencing from the current dataset. The second reference is to the dataset from which you are attempting to look up a value. The third expression is the field you are looking up and the dataset should be the one you are attempting to look up a value from, not the current dataset scope.
Lookup(source_expression, destination_expression, result_expression, dataset)
From the best I can tell, you have a single dataset but separate textboxes that need the correct spend value. I think the following expression will work.
= IIF(Fields!skill_name.Value = "First Aid", Fields!skill_spend.Value, Nothing)
This expression should get the skill_spend value associated with the row "First Aid" only and leave the textbox blank otherwise.
I have been working on this for days without being able to solve yet. It's probably simple if you know what you're doing. I'm simply trying to make a standalone formula that is not in a tablix or anything, it's just in a textbox.
Here is an example of my Dataset called Dataset1:
What I am trying to get is a sum of the Actual Cost when the Category is Labor from Dataset1. My current expression is:
=Sum(iif(Fields!Category.Value="Labor", Fields!ActualCost.Value, 0), "Dataset1")
I refer to Dataset1 as my scope because otherwise, I get an error about using an aggregate expression without a scope.
The report runs but shows #Error in the textbox that has my expression in it. When I replace Fields!ActualCost.Value with a 1, I get the answer, 5, which is the correct number of rows with Labor as the Category. But it won't let me sum the numbers in the ActualCost column where Category is Labor.
Any ideas as to what I'm doing wrong? I feel like it's something to do with aggregating, but I'm not sure. Thanks!
It may have to do with the datatype of fields!ActualCost.Value. If that field is a decimal (regardless of how you have it formatted), try using cdec(0) instead of just 0 in your expression.
I have added a Filter in Row Group-> Group Properties to perform sum of quantity only for those transactions which have done before a certain date.
Whenever I am selecting the 'Cdate' as Expression field from my dataset1, the type is showing as Date/Time but after saving it when I check,I found it as 'Text'. As a result the filter for 'cDate' is not working during report generation.
Note that, I can't filter the data in dataset side or tablix side as I have to show all the column items. This is a matrix report.
OK this is going to be a bit confusing because your dataset contains a field with the same name as one of the built-in expression functions ("CDate" - Convert to Date).
I sometimes run into these datatype issues when using filters and I find the best way to handle it is to force both the filter field and the filter value to be the same data type.
So in your case try setting the Filter expression to:
=CDate(Fields!CDate.Value)
then select the operator as "<=" and set the value using an expression as well:
=CDate(Parameters!MyParameter.value)
and see if that works.
I understand you so that your date field in the dataset is called CDate, try casting it as date, so instead of selecting it in your filter, type the following into the filter
=CDate(Fields!CDate.Value)
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.
