I am having two input for dates as below & want to set alert for that
Alert:- If difference between StartDate & EndDate is more than 6 months,it must generate alert / prompt panel showing text "Month Period exceed than 6",
& report should not proceed further, untill & unless the user select dates between six months.
As far as I know you cannot configure this in JaperReports Server as is, you'd need to implement some logic around import control validation which might be rather complex given the fact that input control rendering is based on a single template and lots of configuration.
However, you can implement the desired validation easily in the report itself:
create another parameter datediff that contains as default expression the calculation of the date difference in months (the parameter needs to be specified below the 2 date parameters)
The way to utilize this information depends now on your particular report design, here an example:
extend your report query with where clause and 6>=$P{datediff}. This would only return results if the date difference is less or equal to 6 months
add the no data band to your report and add there the desired error message.
modify your report configuration for when no data to no data section.
redeploy your report to JasperReports Server.
The desired behavior is now available.

I am currently working on a dashboard in tableau, which shows the count of New-User-Signups and Interactions side-by-side given different date windows. The first New-User-Signup happened before the first Interaction, and the last Interaction happened after the last User Signup.
In order to choose a date window, I linked the date fields in both data sources, and made a date filter, which I applied to all worksheets using related data sources.
However, depending on which "date" field I choose, (from the User Signup table or the Interaction table), the "All Dates" option of the date filter only goes from start to end of that data source's date range.
No matter what I try, I exclude some entries in either one graph or the other. How can I make the "All Dates" filter go from the minimum first date between both data sources, to the maximum last date between the two data sources?
I run into this issue a lot with the data that I use. The problem is that the filter will only be able to contain dates that are in the dataset it is created off of, even if you link the data sources. When I run into this issue, I use parameters instead.
You can find instructions here:

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 created a Crystal Report for some of my users with a date range parameter set. The volume of information that the SQL command returns means that anything over a 7 day period in the date parameter slows the report to unusable speeds and subsequently locks the DB for all other users.
Does anyone know of a way to create a prompt in Crystal Reports that will appear before the parameter set? I.e. As soon as they select the report and click "Open", the first thing they see is a box saying "Please ensure a maximum 7 day date period". Then upon clicking "OK" or something of my choosing, they are presented with the parameter fields and can continue with the report.
If this cannot be done, is there a way to restrict the parameters so that when the users select the start date, they can only select a maximum of 7 days after.
The other option, if it is doable, is to have them select the start date and then it auto complete the end date with a date 7 days after the start date.
At the moment i have just added (Must be a 7 day period) to the parameter title but i dont feel this does a good enough job at advertising it and as soon as i publish it i know someone will want to get 4/5 years worth of data...our clinicians will be most unimpressed if they PAS system locks up during a busy clinic.
I have attached a screenshot of the kind of thing i am after. It is a little crude as it was done in paint but it gets the point across.
I have searched high and low for this solution so i am not sure it even exists, but am asking out of sheer desperation.
Thanks in advance,
Mike
If you use Crystal Report solely (not within a program like .Net app) you can select your latest proposition. Get start date and in your SQL command (View, Stored Procedure, ...) select items from startDate to startDate + 7 days.
Depending on your DBMS there are ways to add some value to date (like dateadd function in MSSQL).
So its done.
I am looking to setup a report subscription in SSRS 2008 R2 where the client user can set the date parameter to whatever the individual user would like. I have been reading multiple suggestions to use =Today() in the parameters but this syntax does not work for me. Does anyone know whether is is possible to set my from date to "Today -30 days" and my to date to "today"? What is the syntax used in the subscription parameters?

As described in the above link provided by praveen the solution became to create two parameters in the report containing integer values with a label that describes the periods i would like to use in my subscription. These parameters can easily be set to "Hidden" so they are not showing when you would like to run the report by hand. I also chose to set the default value for both parameters to 1 which is my value for Today(). This mean my report will start out with having today's date selected in both of the visible date parameters.
In the two date parameters that are shown in the report you can then set the default value to a switch of the values you are able to pick in your hidden date parameters. You can now setup a subscription that will work and that looks like the following:
I have used iReport to create a simple JasperReport which I run on a JasperServer. It queries some fields from a number of MySQL tables based on their creation timestamp. I am providing the start and end timestamps of the period to cover in the report as parameters of type java.sql.Timestamp. This works fine.
I was asked to introduce the ability to show a break-down on weeks or days of the report data. I would like to get some ideas on where to start with this. At this point I don't think I can accommodate this 'break-down' in the report query, since this feature seems beyond what SQL is designed to do. I know this sounds like an OLAP drill through, but I would like to avoid OLAP if possible (steep learning curve, tight deadlines).
My first thought was to create a subreport for each week or day . But this would leave me with an arbitrary number of subreports (depending on the overall time period covered by the report, which varies at each execution), and as far as I can tell iReport does not support this.
Here is one way to break the report down.
Create another parameter, groupby, which holds the a value that designates the grouping requirement. The values can be numeric, string or whatever else as long as it corresponds to day, week, month, etc.. grouping available.
Create a report group, breakdown, which will provide the breakdown. The group expression will depend on the groupby parameter. The expression is the date on the record except any detail finer than groupby value will be trimmed.
Create a variable, total, that will sum the data in the records. The variable should be reset on breakdown group and can be printed in the breakdown trailer band.
Make sure the sql queries sortby the date so that the groupby expression works.
Let me know if you have questions.
