SSRS Report issue while adding column in tablix group setting - mysql

I am having issues with an SSRS Report. I need to modify the SSRS report that has nested tablix grouping. I need to add a single column in that group, but I want to take the sum of values in that column and exclude grouping settings. Is there any way to do that?

Is there a way to automatically add more tablixes?

Currently I'm creating a report with multiple Tablixes. Each Tablix shows the same information as the other Tablixes, filtered on a different group.
So, Group 1 has a Tablix, Group 2 has a Tablix, Group 3 has a Tablix, etc.
Now, the amount of groups will grow over time, with yet unknown names/identifiers.
What I'm trying to achieve is that when a new group gets added, a new Tablix is automatically added to the report as well.
Is this in any way possible? Or should I manually expand the report when such a group is added?
I was thinking about using a parameter that counts the amount of groups, then creates that many columns in a Tablix, and have the column automatically populate with another Tablix, but I believe it's not possible to have a Tablix with a fluid number of rows within another Tablix.
Cheers,

SSRS Report - using the value from the subreport in a calculation in my main report

I am writing an SSRS report using report builder and have my main report and a sub report - I have had to do this because one of the figures is in a different table. The main report shows a customer column an amount column then my subreport column - in the next column I need to show these two figures added together, there is then a further column with another figure in and the final column will deduct the fourth from the calculated third - I dont know how to write an expression which incorporates the subreport value.
You can't retrieve values from a subreport like you wish as that's not how subreports work.
When you run the SSRS report, the parent report passes parameters to the sub-report (the only data transfer between the two), the subreport is rendered and then the rendered subreport is inserted back into the parent report as the parent report is rendered.
As I see it, you have two options to tackle the problem.
1) Join the data from the two tables in your source query so that all the appropriate information is within one dataset in your report.
2) Use the Lookup function to retrieve values from the second dataset. This is a very flexible option and one that I highly recommend that you review for scenarios like this.

SSRS - Get current tablix iteration index

I have a report which contains a tablix. Within this tablix I have a subreport that is called at each tablix iteration.
I would like to obtain the current index of the tablix iteration inside the subreport. I have passed a subreport parameter using below expression:
=RowNumber("dataset")
dataset is the one assigned to the tablix in the report. In my concret case, this expression is not working.
Any other way to get this work?
Is your tablix grouping the data from your dataset? If so, can you do that grouping/aggregation in your SQL and return only the final dataset in the format the tablix will be displaying it?
If you can manage that, you can simply add a ROW_NUMBER() OVER (ORDER BY <column names>) as RowNum and pass that through as =Fields!RowNum.Value to your subreport.

Creating a group in SSRS

I have around 10 tables in an ssrs report and I need to add a group which includes them all. Is there a way to do that in ssrs?
I know how to create column and row groups within a single tablix, but I am not able to do the same for more than one tablix.
I created a table with a single cell, then inserted a rectangle in it and then copy/pasted all the tables in there. Then added a row group and it works!!

How to display average in an SSRS table?

I am using SSRS 2008 and one of my rows is supposed to return the average of a certain field. But currently it just displays all of the rows instead of one row with the average. How do I implement this?
Currently the stored proc for this RDL file returns all of the records. So I tried using the "Avg(<field value>)" function in SSRS for the SSRS expression. And then I grouped this row on the <field value>. I removed filtering so it should average all rows now.
I'm guessing the cause is the grouping. Any ideas though?
I think you need a totals row. Right-click on the group and then Add Totals Then you should be able to put your Avg(<field value>) in that cell.
