Crystal Reports 10, Want to pass values from subreports to main report

Post Author: playmkr278
CA Forum: General
Is there a way to just share values out of subreports.
The reason I ask is that I am having problems pulling the correct information in one subreport so I'd like to use 2 subreports to pull out Billable hours on one and Billed Hours on another and then add them together to display on the main report.

Yep there is!
In your sub report
I the formula editor create a shared variable then create the same variable in your main report.
EG
IN your SUB
Create new formular called tothrs etcu2026..
whileprinting records;
shared numbervar tothrs: sum({table.fieldname}]
In Your Main Report
whileprinting records;
shared numbervar tothrs
this passes the value from your sub to the main, check help for different types of format as the one above is only for a number there are others for time & date etc..
hope this helps!
I have been doing a similar exercise myself but got stuck summing the parameter values in my main report, if you solve this let me know?

Passing values from subreport to main report

Dear All,
I have used shared values in my sub report and i want to use that shared variable in my main report in one of the formulas for average calculation but i see the values as 0.
Can someone let me know what I am missing.
Regards,
Sonali

Hi
The most important thing to remember when using shared variables is that Crystal Reports must first evaluate the formula where the value is stored before evaluating the formula that retrieves the shared variable.
For example if you want to pass a grand total from the subreport to do a calculation in the main report, follow these steps:
1. In the subreport, create a formula similar to the one below:
//@SubFormula
//Stores the grand total of the
//{Orders.Order Amount} field
//in a currency variable called 'myTotal'
WhilePrintingRecords;
Shared CurrencyVar myTotal := Sum ({Orders.Order Amount})
2. Place this formula in your subreport.
3. In the main report, create a formula that declares the same variable name:
//@MainFormula
//Returns the value that was stored
//in the shared currency variable called
//myTotal in the subreport
WhilePrintingRecords;
Shared CurrencyVar myTotal;
myTotal
4. Place @MainFormula in a main report section that is beneath the section containing the subreport.
NOTE:
For the shared variable to return the correct value in the main report, you must place @MainFormula in a main report section that is beneath the section containing the subreport. This ensures Crystal Reports evaluates the @SubFormula before @MainFormula.
One way to do this is to insert a section below the section containing the subreport, and place @MainFormula in this new sub-section:
· On the 'Format' menu, click 'Section'.
· On the 'Sections' list, click the section containing the subreport.
· Click 'Insert' (at top of dialog box). This inserts an additional subsection.
· Click 'OK' to return to the report, and insert @MainFormula into this new sub-section.
The next time you preview the report, @MainFormula displays the value from the subreport. In this particular example, that value was the grand total of the {Orders.Order Amount} field.
5. Once you have verified that @MainFormula is returning the correct value from the subreport, you can include this formula in other main report formulas, such as:
//@NewFormula
//includes data from subreport
{@MainFormula} + Sum ({Customer.Last Year's Sales})
· Place this formula in the same section as @MainFormula, or in a section further down on the report.
You have now successfully shared data from a subreport with the main report.
NOTE:
This is not possible with On Demand Subreports in Crystal Reports since the report will not be processed until after clicking report.

How to get shared date value from subreport to main report

Hi,
I need your help in passing the value of a running total that is located in the subreport to the main report. The running total in the subreport is getting the maximum of the Effective Date (which it is type in the database is date) for each group and it is value will change on the change of the sequence no. group. I am printing the value at the group footer which displayed correctly. Now my issue is that how to pass the value from the subreport to the main report as a date. I have created a formula that it is having the code:
shared datevar ddd := date(0,0,0);
ddd:={RTotl0}
The above formula is not compiled and it is first giving me an error at line 1 that date(0,0,0) is not accepted. Then when I removed it, it gave me an error that ddd:= can't have a running total to a datevar.
So can you please help in getting the value from the subreport and then to pass it to the main report as a formula as I need to include it in other formulas which it compares the dates.
Thanks

Hi Mohammed,
Are you displaying the shared variable on the Main Report's group footer as well?
Try changing the code to:
shared datevar ddd := cdate(0,0,0);
ddd:= date({RTotl0});

Passing Array From Subreport to Main Report then Summing

Hi,
I am having troble passing an array from a sub report to the main repport. I have managed to create the array, pass it and display it in the main report, however the first value of the array is displayed twice. Here is the formulae I have used:
In the sub report:
whileprintingrecords;
shared stringvar str;
str:=str{@value}","
In the main report:
whileprintingrecords;
shared stringvar str;
stringvar array arr;
arr:=split(str,",");
join(arr,",")
Also, when I have managed to resolve the problem of the first value printing twice, I hope to change the array back to a number array and sum all of the values together. I'm not too sure how to do this either.
I hope you can help.
Julie

Ummm... Isn't Join(Split(str,","), ",") = str? Why bother with the two extra lines of code? Also, are you sure the subreport isn't creating the "duplicate first value"? (I.e. The data has the same value on two records, so it's being added twice?)
Also if you're looking for the sum, why not create another shared variable and sum the value in the subreport as you're building the array (assuming you need the array for other purposes)?

Passing a variable from subreport to main report

Hello,
Was hoping to get some assistance on this issue I'm facing. I've got a sub-report that calculates a monthly goal based off the date selection criteria. And I'd like to pass this goal back to the main report.
In my sub-report, I created a new formula named ProcGoalVariable:
WhilePrintingRecords;
Shared Numbervar ProcedureGoal := cdbl({#ProcGoal})
While {#ProcGoal} is a running total I created for the sub-report and now I'd like to pass it back to the main report.
In the main report, I created a new formula named ProcGoalVariable:
Shared NumberVar ProcedureGoal;
ProcedureGoal;
But when I drop this into my report, it is returning a value of 0. In the screen shot, the Proc. Needed should actually equal the Proc Goal:
Any suggestions on how to pass this correctly?

Thanks for the advice,
I want to rewind a bit to make sure I am explaining myself clearly. My sub-report is pulling the correct numbers and it is located in GF#3 and contains two values that fall under "Proc Goal" and "Prod Goal". These are being calculated correctly and I would then like to pass them back to the main report for additional calculations done on this.
In the sub-report, a formula was created "ProcGoalVariable":
WhilePrintingRecords;
Shared Numbervar ProcedureGoal := cdbl({#ProcGoal})
In the main report, a formula was created "ProcGoalVariable"
Shared NumberVar ProcedureGoal;
ProcedureGoal:=ProcedureGoal;
Would having the same name inside the formulas being causing the issue? And I've tried inserting a new section below the section where my subreport lives and I still get a value of 0.
Not sure what else to try at this point.

Passing Shared Variable from subreport to main report

Hello,
I am having difficulty passing the shared variable from the subreport to the main report. For some reason, when viewing the data, the value for the very first row is returning a 0 but the second row is returning the value that should be in the first row. Does anyone have an idea of what I'm taking about?
Thanks.

In Subreport there is a group based on the client. There is a summarized amount field in this grouping. I placed a formula in the grouping and suppressed it. The suppressed formula is listed below.
{@ store client payments}
WhilePrintingRecords;
Shared CurrencyVar cRelatedPayments;
cRelatedPayments := cRelatedPayments+Sum ({amount.amt}.{client.client_number});
cRelatedPayments;
In the main report, there is 2 groupings, first grouping is the client and second is the invoice. The client grouping is displayed while the invoice grouping is suppressed.
The following is the formula in the main report to get the shared value.
WhilePrintingRecords;
Shared CurrencyVar cRelatedPayments;
cRelatedPayments;
This is placed in the client grouping.
I hope this helps.

can anyone plz help me out for this..
Thanks in advance..

Hi,
Try to set your values in Method->"wddomodify" of the View in which Adobe Form is present. If you want to pass values from one view to another then check this link [Passing Local Parameters between views in an ABAP Web Dynpro Application|http://wiki.sdn.sap.com/wiki/display/stage/PassingLocalParametersbetweenviewsinanABAPWebDynproApplication] or use Context declared in Component Controller.

How to Pass values from XML to JSP??? Urgent Please Help me

Hi guys,
I am new to XML, I want to pass values from XML to JSP. I have a xml file with attributes, I should send this values to a JSP file. How is it??? Please Help guys.... its very urgent. Please send me how to do it with an example or atleast any urls related that....
Looking for ur favourable reply.
Thanks in advance,
Sridhar

in a servlet :
parse your xml file (see how at the end of the post) and
put the values you want in the request attributes
request.setAttribute("value1", value1);
...redirect to the jsp
in the JSP:
get the wanted attributes:
String value1=(String)request.getAttribute("value1");To learn how to parse a xml file, pay a look at this page, it explains how to read the XML document to build an object representation, and then how to navigate through this object to get the data

Java Thread - difficulty while passing value from parent to child thread

Hi All,
I am calling a java program from a unix script .
My oblectives are
1)to pass value from scripts to main java class
2)main class should create a child thread and pass data to child and should return control back to script
3)child thread should run independtly of parent
The calling unix script is part of process and hence should return control back to its calling script immediately.
Findings
1)Without passing data thru setter getter /constructor method to child thread my objectives are met
2)When I pass the data from parent thread to child thread calling unix scripts wait till child thread finishesh its working
call.scr
java Main <list of Arguments>
Main.java
public class Main
             public static void main(String args[]) throws Exception
             String data2="Z";
             String data1=null;
             for(int i=0;i<args.length;i++)
                  data2=data2+","+args;
data1=data2;
Child cu=new Child();
cu.setData(data1);
data2=null;
data1=null;
cu.start();
Child.javaclass Child extends Thread
public String data;
void setData(String data)
this.data=data;
public void run()
----------> processing on data
I think due to passing of data from parent thread to child thread (Inter thread data communication/Inter process communication)
the threads are not working as desired.
Plz anybody can suggest something.....
Thanx.

aschin,
You seem to be confusing Java Threads with Operating System Processes.
If you want you're java program to run in the unix background then you'll need to run it in the unix background. Java (being o/s agnostistic) doesn't provide process manipulation functionality (which would include the ability to throw itself into the background, as a C program can) in the standard API, and it's hard to imagine any third party producing anything as low level as a process controler... so yeah, just start the java program in the background... and you'll need to workout some interprocess communication protocol... named pipes have worked well for me in the past, as they doesn't suffer from the quit same performance issues as real disk files.
Good luck. Keith.

Passing values in Subreport

Hi,
In GH1: i have one subreport
In GH2: i have two or three subreport
My question is, i have to pass the GH2 sureport values to GH1 Report Header. can any one explain?

by using shared formulas.
These are my personal crib notes and formula names to remind me how to do it:
Shared variable formulas for subreport/main report,
must use same <var name> in each shared formula variable declaraions.
also use the same <var name> in naming shared formulas & in related running
total formula names and declared variables to mentally link them together.
Shared formulas work in either direction. Order of appearence on report controls
primary/secondary. To go from subreport to main report, @mainform.<shared var>
must appear after the subreport in the main report.
subreport shared formula - primary; must "print" in subreport-can be white text
and/or off the 'page' but do not suppress
1. {@subform.field1} <<<sample formula
////{@subform.<var name>} stores the figure to be shared with main report.
whileprintingrecords;
Shared numberVar <var name> := <source field or formula name>;
main report shared formula - secondary. must "print" in main report after subreport;
can be white text and/or off the 'page', but do not suppress; use same <var name>
as subreport formula
2. {@mainform.field1} <<<sample formula
//{@mainform.var name>} retrieves {@subform.<var name>}
whileprintingrecords;
shared numberVar <var name> ;
<var name>
You could then share the formula to the next subreport by putting the shared formula
{@subform.field1} in the next subreport.

Passing Value from Crystal Report (special function) to Business View parameter

Friends,
Í have a scenario where i need to pass value from Crystal Report to a Business view's parameter.
Eg : CurrentCEUsername (func in crystal report)-- gives login user which i should pass to parameter in a Business view (used in the same report).
Will be able to explain more if required.
Thanks in Advance,
Bharath

I guess you got the picture wrong. User_id is not a report_level parameter .
In Data Foundation, below query is used..
select Acc_Number, Account_Group,User_id from Accounts where user_id={?User_id}
where in {?User_id} is the BV parameter...
The Filter was a solution. But it takes long time to Query all the data from DB and then filter at BV level.
How do i pass the CurrentCEUsername to {?User_id}
Value should ve CurrentCEusername always. so that query will be
select Acc_Number, Account_Group,User_id from Accounts where user_id=CurrentCEusername
It will restrict the data pulled from DB to BV .. right?
