I've a report with a subreport. I would use all data of one column into a loop and then write the result into footer table. How can I do?

SSRS: How To Create Dynamic Report With Multiple Subreports?

I am still fairly new to SSRS, and I do not know what I need to/can provide as examples to help clarify my issue.
I am developing an SSRS report that accesses a NAV database and generates a report for an equipment number. My task is to generate a master report that can print multiple of those kind of reports(currently 10 max). I am using sub-reports to get the content that I need for an equipment number.
I am looking for a way to make this dynamic, where I can generate 1 to n sub-reports based on how many values were picked for the multi-value parameter. The end result should be one PDF file that contains the full report for each equipment number listed. I am trying to only use SSRS.
I have seen where I could hide sub-reports then make them visible if a condition is met, but this isn't the functionality that I am looking to use. So, what would be the best way to dynamically generate sub-reports based on a multi-value parameter?
I figured it out. I made the sub-report parameter equal no value. I made the main report with a parameter that can select multiple equipment numbers, a list, and a data set which filtered down to the appropriate equipment numbers to avoid duplication. I made the sub-report object in the main take in the cell value from the list equipment number. When the list proceeded to the next row, it copied all of the objects in the box area.

How to change the parameter type in crystal report of the existing report?

I have a crystal report with 2 subreports. The type of the one of the field got changed in the database from number to string. The main report has no parameters but the subreport has this parameter. Now when I try to run the report I get the error in the record selection formula. A string is expected here. My question is How do I make the type change for that field so that I can run my report. ?
Easy to do. And FUN, too!
Assuming you can change the link to the subreport, you can:
1) create a formula to manipulate that field in the main report, explicitly converting it into the format you neend. Then,
2) use THAT formula as the link to the subreport
Should work a charm, "Bob's yer oncle", and all that.
The solution was to remap the bindings of the report with the changed datatype in the dataset

Generate Column Total In Main Report From Sub Report - Pentaho

I'm creating a report in pentaho report designer.
I have a sub report in my main report where it gets some values. I want to display the sum of those values from the subreport in the main report.
Or even better, if you JUST want to display it on the report and not use it in any further functions, simply drag the field you want total'd into the group footer or report footer section, click on the wizard-aggregation attribute and set that to Sum.
The function should be used if you want to refer to the total in other ways, i.e. in additional formulas etc. Because this "wizard aggregation" attribute is only a display attribute really.
Use the function Sum by right-clicking Functions, and then Add Functions. Add to that the field (under field name) which sum of values you want to be displayed in the main report. After that, just drag the function you made onto your report.

Dynamic SSRS report

I had a problem in creating the Dynamic report in SSRS. My problem is:
In a table I have stored SQL scripts with the column SQLScripts. If you execute these SQL scripts you get different number of columns for each script.
My problem is, I have one report with buttons of these scripts, for example test1, test2...like that. If you press test1 button this should take the test one SQL script and should display the report with appropiate columns in that sqlscripts.
I can't create individual reports for each test report, they are plenty. Are there any options for me to solve this problem...
The only way I've been able to get this to work sofar is:
Each report has 2 datasets.
ReportData
DataHeaders
The "DataHeaders" need to have the proper name of the datafields in "ReportData". Be careful since SSRS replaces blanks and special characters with "_"
Now, create a table (or matrix) and drag the DataHeaders as the Columns of your report. (This should be a grouped column). If you run it at this point, you'll see all your columns without any data. Now comes the magic:
Create another report that takes a "DataField" parameter. Create another table or matrix within this report and set it's dataset property to be "ReportData". In the DATA cell for the table, set it to the expression =Fields(Parameters!DataField.Value).Value
Now go back to your first report. Right click and insert a subreport. Right click on the subreport and select "Subreport Properties". Under general, select the second report you created to be used as the subreport. Under parameters, select the DataField parameter and set its value to something like =Fields!DataField.Value
In my case I did some formatting in this expression to fix the above mentioned issue with spaces and special characters, since my stored procedure was initially used in ASP.NET and this was just a proof of concept.
Also in my experience the performance isn't great. In fact it was kinda slow, though I haven't had a chance to switch it to use a shared dataset, which I suspect would help a bit. Please let me know if you find a better solution.
I have not found a way to do this completely dynamically. Here is a similar question with some possible solutions:
How do i represent an unknown number of columns in SSRS?
You basically need to create a 'master dataset' from the other Datasets that are based on your multitude of SQL scripts first.The master dataset should contain the data to be presented in it's most simplistic form, i.e. in a simple list format.
Finally, go to the toolbar in SSRS and drag a 'Matrix' into the report. A Matrix table acts similar to a pivot table in Excel or a CrossTab query in Access that will display whatever's in the Dataset.

Inserting a page break in Crystal Reports programmatically

How do I insert a page break in Crystal Reports. Using VB.Net, not in the report definition?
The best technique I've used for stuff like this is to group on a formula. Set the report to break on that formula, then you can set the value of the formula in your .Net code to a value that'll break where you want to break.
Using this technique, you can create a single report and have it dynamically sort and break on any field (or formula) you want at runtime, which makes the report very versatile.
