Using SSRS 2010
I have Two groups YearMonth and Insured. I need to display only 50 records per page based on a group "Insured". So I have created parent group "GroupPageBreakOnly" and used this expression =CEILING(RowNumber(Nothing)/50).
I ensured that the Page Break at end is checked so that individual groups appear in individual page.
As a result the first page displays 31 rows, the second one 50 rows, and the third one 9 rows.
I tried to specify data region "Insured"
=CEILING(RowNumber("Insured")/50),
but it gives me an error:
...the value of the scope parameter of RowNumber must equal the name of the group directly containing the current group.
What am I missing here?
Unless you need this report to do other things, I would apply the grouping and aggregation in the Dataset itself which is generally a lot more efficient anyway.
Have you tried using ROW_NUMBER() OVER (PARTITION BY YearMonth, Insured ORDER BY YearMonth, Insured) to give the number of rows, perhaps even throwing in a % 50 at the end to see which group of 50 it fell into?
This can then be grouped on in your report.

How would I select a rolling/wrapping* set of rows from a table?
I am trying to select a number of records (per type, 2 or 3) for each day, wrapping when I 'run out'.
Eg.
2018-03-15: YyBiz, ZzCo, AaPlace
2018-03-16: BbLocation, CcStreet, DdInc
These are rendered within a SSRS report for Dynamics CRM, so I can do light post-query operations.
Currently I get to:
2018-03-15: YyBiz, ZzCo
2018-03-16: AaPlace, BbLocation, CcStreet
First, getting a number for each record with:
SELECT name, ROW_NUMBER() OVER (PARTITION BY type ORDER BY name) as RN
FROM table
Within SSRS, I then adjust RN to reflect the number of each type I need:
OnPageNum = FLOOR((RN+num_of_type-1)/num_of_type)-1
--Shift RN to be 0-indexed.
Resulting in AaPlace, BbLocation and CcStreet having a PageNum of 0, DdInc of 1, ... YyBiz and ZzCo of 8.
Then using an SSRS Table/Matrix linked to the dataset, I set the row filter to something like:
RowFilter = MOD(DateNum, NumPages(type)) == OnPageNum
Where DateNum is essentially days since epoch, and each page has a separate table and day passed in.
At this point, it is showing only N records of type per page, but if the total number of records of a type isn't a multiple of the number of records per page of that type, there will pages with less records than required.
Is there an easier way to approach this/what's the next step?
*Wrapping such as Wraparound found in videogames, seamless resetting to 0.
To achieve this effect, I found that offsetting the RowNumber by -DateNum*num_of_type (negative for positive ordering), then modulo COUNT(type) would provide the correct "wrap around" effect.
In order to achieve the desired pagination, it then just had to be divided by num_of_type and floor'd, as below:
RowFilter: FLOOR(((RN-DateNum*num_of_type) % count(type))/num_of_type) == 0
I have made a simplified example to illustrate the question i'm trying to ask here. In my example i have sales orders and each sales order has multiple lines, i group by Sales Order Number, then by Sales Order Line (row groups)
I have found Group Filters very useful/flexible in filtering report data in specific areas of a table, so in my example i filter the SOLine group to exclude the SO line if it equals 3.
Then, i want to have a group aggregate for the entire SO, to tell me a count of the SO lines within it. Unfortunately when doing COUNT() expression from a textbox within the Sales Order Number group scope it counts all the lines, including the SO Line 3, whereas i want it to take into consideration the line filtered out from its child group.
Below is a screenshot of my tablix and grouping:
On the SOLine group i have the following filter:
And below is the output i get when previewing the report:
I want that count to evaluate to 4, but i ideally want to keep using groups as i've found they are much more efficient than using SUM(IIF) which completely slowed down my actual report which has thousands of rows.
If this is not possible, please give all best alternatives i could use.
Many thanks.

I have a requirement for a dynamic report where the user can select what columns they want to display. This is not a problem for me to do using render variable, however, the measures are not rolling up.
As an example, I have age, gender and sales. This generates say, age 20 and 25, and obviously 2 genders, resulting in 4 rows.
When you remove gender using the static choices in the prompt page, it keeps 4 rows, just without displaying the age. I understand this is the nature of 'rendering' (or not) the column.
What I need is for the measures to roll up to what columns are left, which would show 2 rows, and a total. Or even remove all columns, and have just an overall total sales left.
I cant really use conditional blocks to create every combination as there is going to be 20+ columns in the report.
Thanks in advance!!
Change you conditionally rendered field to something like
case when ?render_gender? then [Gender] else '' end
This should zip your four rows to two.
I'm currently writing a stored procedure for my client to populate some tables that will be used to generate SSRS reports later on. Some of the data is based on specific stock formulas that are run on each of their clients' quarterly data (sent to them by their clients). The other part of the data is generated by comparing those results against those from other, similar sized clients. One of the things that they want tracked in their reports is the average of the top 25% of formula results for that particular comparison group.
To give a better picture of it, imagine the following fields that I have in a temp table:
FormulaID int
Value decimal (18,6)
I want to do the following: Given a specific FormulaID return the average of the top 25% of Value.
I know how to take an average in SQL, but I don't know how to do it against only the top 25% of a specific group.
How would I write this query?
I guess you can do something like this...
SELECT AVG(Q.ColA) Avg25Prec
FROM (
SELECT TOP 25 Percent ColA
FROM Table_Name
ORDER BY SomeCOlumn
) Q
Here's what I did, given the table shown above:
select AVG(t.Value)
from (select top 25 percent Value
from #TempGroupTable
where FormulaID = #PassedInFormulaID
order by Value desc) as t
The desc must be there, because the percent command will not actually do comparisons. It will just simply grab the first x number of records, with x being equal to 25% of the count of records it's querying. Therefore, the order by Value desc line then will grab the top 25% records which have the highest Value, and then sends that info to be averaged.
As a side note to all of this, this also means that if you wanted to grab the bottom 25% instead, or if your formula results are like a golf score (i.e. lowest is the best), all you would need to do is remove the desc part and you would be good to go.
I'm working on SSRS report builder that is using a dataset calling a SQL Server 2000 database.
The query is getting sums of a few different fields and is also pulling out all records that have to do with that client number. I want to get the sum of the sum but it is way over because of the detail rows. Basically what I want is the sum of the distinct sum column values.
=Sum(Fields!tot.Value, "table1_Group3")
I saw that you can get sums by the groups and I tried the expression above but it comes back with an error:
The Value expression for the textbox 'tot' has a scope parameter that is not
valid for an aggregate function...
table1_Group3 is the name of the group that holds the sum value in the report.
Any suggestions on how to get the distinct values to sum them in this report.
=Sum(Fields!tot.Value, "table1_Group3")
The code above will give you the sum of "tot" for all rows in the current "table1_Group3." This means that this expression only makes sense somewhere within table1_Group3. Otherwise, SSRS doesn't know which is the current instance of that group.
Sounds like you would like to sum this value across multiple groups, but only take one "tot" from each instance of the group. (Are you sure that all rows in that group will have the same "Tot?")
If tot is the total of other fields in your returned data, then simply add those up in your formula. This may have the added benefit of simplifying your SQL query as well.
Some other options that could work:
- Change your SQL query so that only one row per group gets the Tot field set.
- Use Embedded code in the report to keep a running total which is added to only once per group, such as in the group header.
(If upgrading to 2008R2 SSRS is an option, then the Lookup function could be used here, maybe even to look back at the same dataset.)
change the query/ dataset to sum(distinct tot) using the temp table on the sql server
I suppose you need to write sum(distinct columnName).
