How ordering between sub reports - jasper-reports

I have one report has two sub reports(A and B)
How to get B initializing after A,because B has a parameter is depended to A
Another hand how ordering between sub reports in jasper
Is it possible?my request is logical?

I suppose you can manage your order with a management on your report structure.
If possible:
You have a MAIN report
Under the MAIN report you can define a sub-report named A.
In the sub-report A you can define a sub-report B (so all B linked to your A will be exposed after the main A).
A simple example:
Main report: List of Italian football team of Lega Pro level (for example Taranto, Matera, Foggia and so on). This is your MAIN report.
For each team you have a list of football players.
To explode this list for each team, you have to define a sub-report named A.
For each player you want to show all matches where this player have taken apart.
You have to define a sub-report named B under A.
UPDATE
To manage this flow:
Main Information
A information (all rows)
B information (all rows)
The first part:
Definition of your data structure
You must have a main object with two listes.
A list for A information
A list for B information
The second part:
Definition of report structure
You must define two different subreport as follow:
In the main report you add two details band.
In the first detail band add a link to subreport A
In the second detail band add a link to subreport B
In this way. As first you process all A rows and the you'll process all B rows

Repeat main report rows per each subreport row

I have a JasperReports's report already implemented using below data structure which prints a main record along with its subreport records. The main and the subreport are placed in the same detail band and the subreport uses the JRBeanCollectionDataSource($F{employees}) as its data source expression $F{employees} being the collection field on the main report data type Company.
Company
Name
Location
Employees
Employee
ID
Fullname
etc.
The question is if there is an option in report to repeat the main report columns (Name, Location..) for each subreport record I have for a certain Company?
Basically, I need repeated records in the main report.
I know this is ugly and may look pointless but that is the Business Requirement! Most importantly, I don't want to touch the existing data structure as it's more complex in real case than my example.
Any hint (could be even a hack in JasperReports) is highly appreciated.
Note: I'm using iReport 3.7.3 editor.

Form prints multiple times when more than one record is pulled in sub report 2

In Crystal reports I am making a summary statement and I got all of it but 2 parts are giving me trouble... I have two sections that needed to be totaled so I made subreports and put them in detail a and detail b. Each section potentially can have multiple sections or no sections. whenever there is more than one line in detail b or sub report 2 it prints the whole report that many times. So if there is only one record in Detail B it prints like
header a
detail a
footer a
header b
detail b
footer b
But if there is 2 records in detail b it prints
header a
detail a
footer a
header b
detail b
footer b
header a
detail a
footer a
header b
detail b
footer b
And the pattern continues if there is 3 records in detail b.
I also need to subtract the total of detail b from detail a. I can grab the number i need from detail b but whenever i try to get the total from detail a it comes back as a 0 instead of the number. Please Help me! Thanks
review your links or create a group on your subreport, so it won't show same info 2ice. Take in consideration that if you are using shared or global variables to show totals from your subreport, it should be place in a different section of your subreport. For example:
If your subreport is on Details Section A, you should place your variable in Section B.
try placing those subreports in your report header rather than your details. Create another 2 RH sections and place them on it

How to show data in multiple columns in report

Requirement:
I have a table in DB as below:
COP_MASTER
-----------------
CopDuty CopName
Duty1 Alpha1
Duty2 Alpha2
Duty1 Alpha3
Duty1 Alpha4
Duty2 Alpha5
Using iReport I need to prepare a report where the report looks like this:
CopDuty CopName
Duty1 Alpha1 Aplpha3 Alpha4
Duty2 Alpha2 Aplha5
Here the list of CopNames grows horizontally (or in a simpler terms the columns are dynamic).
I have already tried using subReport and inside the subReport's detail band a List element where the PrintOrder for the list element is kept "Horizontal". But the list grows vertically and not horizontally.
Any advice or help?
Prepare an independent report with the copName as a field to be displayed.
Make the printOrder properties available in the report properties tab as "Horizontal"
Change the Columns value:n (where n>1)
Go the main report and add the subreport element with the choice "Just add the subreport element".
Go to the Properties tab of the subreport element do the following changes as below:
Subreport Expression: $P{SUBREPORT_DIR}+"CopSubReportFileName.jasper"
DataSourceExpression: new net.sf.jasperreportsengine.data.JRBeanCollectionDatasource($F{cops})
Here we have to note that if the "cops" is a BO associated in the "Duty" BO then the above solution is just fine. But if it is to be tested through DB conn directly then the "dutyId" must be passed as report input parameter to the subreport for the corresponding copNames to be fetched and printed.

Break Detail Line in Half?

Currently the detail prints like this:
I want to break the line in half like this:
This is what I have; Not what I want
Notes:
This is all in a sub-report if that makes any difference
I do not yet grok using formulas, variables, etc. to influence what is printed where, when, or how.
I'm working in Visual Studio 2012, I don't know the CR version.
I created Detail a and Detail b sections.
I created 2 Group Header Sections: Group Header 1a and Group Header 1b
I moved all the headers into these two groups and suppressed the Report Header Section (but not the Report Footer). Moved report fields into corresponding detail group.
Now all the detail is printed after both headers are printed. I expected this but don't know how to do what I need.
Totals are printed in the Report Footer, no issues here.
The Mystery is Solved
Created a 2nd sub report
Moved desired headings, details, and totals to the new sub report ReportHeadr, DetailSection, and ReportFooterSection respectively.
Put the new sub report directly below the original in the same (main report) section - it just happens to be a GroupHeaderSection
Changed SubReport Links ... for the new sub report. Set it identically to the original.
Notes
The sub report links setting is key to making this work. Otherwise I was getting all the data records every time this new sub report was generated, resulting in hundreds of pages.
Could not use Siva's answer. The sub report happens to be inside a Main Report's GroupHeaderSection. The report's structure does not make putting the (sub report) content into new groups and detail sections possible.
I did create multiple groups & detail sections in the sub report itself. This still gives me the undesired results illustrated in the original question posting.
if you need to view the output as you required follow below
1. Take 2 detail sections add two sub reports in main report.
2. In sub report 1 place first 3 columns and in second sub report place other two columns

can variable from subreport be used to group information in the main report (crystal 10)

I have set up a main report that has 2 subreports coming into it.
The main report consists of
one table : ROOM & two parameters: STARTDATE and ENDDATE.
The date range is only in the main report so it can be displayed in the title area. More importantly, it links to the 2 subreports.
Right now, the main report is grouped by Facility and then by Room name. Everything is working great until I try to run it for more than one day. What I want is for the main report to also be grouped by the date, but I don’t know if that is possible as the ROOM table does not contain a date field to link the parameters to so that I could use it in the groupings.
Is it possible to create a Date variable within the subreport that could then be passed back to the main report to be used for grouping? I apologize if this is a dumb question, but I do not work with variables often and shared variables even less than any other.
Short answer: No. You can never group a main report with variables from a subreport. Crystal determines a report's groups early in the evaluation process, before it ever looks at any subreports.
In general, you might want to ask yourself how to avoid the use of subreports in the first place. In my mind the use of a subreport is a last ditch effort when there is simply no other way to accomplish what you want in a single report. In your case, if your main report is only made up of a single table (ROOM), then you would simply need to move the tables from your subreport to the main report, then join them to ROOM. Doing it this way would leave you free to easily group on whatever fields you wanted.
You technically can get those values from the sub-report to the main report.
This blurb describes 'Shared' scope variables.
Shared Variables (Crystal Syntax)
Shared variables use the same memory block to store the value of a variable throughout the main report and all of its subreports. Thus shared variables are even more general than global variables. To use a shared variable, declare it in a formula in the main report as in the following example:
Shared NumberVar x := 1000;
and declare it in a formula in the subreport as in the following example:
Shared NumberVar x;
In order to use shared variables, the variable must be declared and assigned a value before it can be passed between the main report and the subreport.
Shared variables are great for aggregates (sum, etc.) that span the main report and one or more sub-reports.
