How to get formula field value from Subreport to main report

I want to get Formula field values and grand totals from two subreports and show in page footer of the main report. I am using CR 8.

Pls help me.

Thanks in advance.

Shared variables, introduced since Crystal Reports version 7, make it
easier to pass values from a subreport to the main report.

Using shared variables requires two formulas:
one to store the value in a shared variable, the other to retrieve the
value from the shared variable.

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:

Code:

---

//@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:

Code:

---

//@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.

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 subsection.

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:

Code:

---

//@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.

I hope You have now successfully shared data from a subreport with the
main report.

Hi jggtz

Thanks for your valuable response.

Thanks for posting this request and response. I was just about to ask this question. I'll try when I get to the office later today and post my results.

THX! THX! THX!

I get this error when creating my formula in the subreport:

"GROUP SPECIFIED ON A NON-RECURRING FIELD"

I'm uncertain what that means.

Any suggestions!

Using the help posted... i could get the sum of amount from subreport to main report. but i am not able to use this formula to some other formula in main report.. not getting any result in new formula.. how do i?
