I have a Non-Conformance report that has a couple of subreports.  One of the subreports displays a sum of invoices by vendor id.  My main report displays the Sum of the Total NC Cost.  I want to calculate the Impact $ which would be (Sum of @ Total NC Cost / Subreport: Sum of Command.ext_recvd)

How do I do this?  

I was reading something about variables, but I have never used them so I don't know how to use them.

Basic idea

In the main report
Add a formula to the report header
WhilePrintingRecords;
Shared NumberVar SubreportTotal;
''

Open in new window


IN the subreport add a formula to get the total
WhilePrintingRecords;
Shared NumberVar SubreportTotal;
SubreportTotal := Sum({YourField});

Open in new window


IN the main report in a section after the subreport add a formula to display or calculate
WhilePrintingRecords;
Shared Number{mVar SubreportTotal;
{MainReportTotal / SubreportTotal 

Open in new window

I created the first formula in the main report and named it calc
I created the second formula in the sub report and named it calcsubreport
I'm trying to create the third one and get a bunch of errors.

Should it really be?  Because I get errors when I enter it exactly as you wrote it down.   When I try to enter my report name in there, I get errors too.

  WhilePrintingRecords;
Shared Number{mVar SubreportTotal;
{MainReportTotal / SubreportTotal

Sorry missed the typo
If the mainreport total is a variable use

WhilePrintingRecords;
Shared NumberVar SubreportTotal;
Global NumberVar MainReportTotal;

MainReportTotal / SubreportTotal
 

Open in new window


If it is a formula
WhilePrintingRecords;
Shared NumberVar SubreportTotal;

{@MainReportTotal} / SubreportTotal
 

Open in new window

My main report is a summary,  Will that work?

So my final formula on the main report is:
WhilePrintingRecords;
Shared NumberVar SubreportTotal;

Sum ({@Total NC Cost}, {@Vendor}) / SubreportTotal

I don't get any errors when I test the formula however when I try to run it I get "Division by zero" error and it highlights
Sum ({@Total NC Cost}, {@Vendor}) / SubreportTotal
0

Anytime you do a division unless you KNOW the divisor cannot be 0 you need to test for it and handle the 0 divisor

WhilePrintingRecords;
Shared NumberVar SubreportTotal;
If SubreportTotal = 0 then
    0
Else
    Sum ({@Total NC Cost}, {@Vendor}) / SubreportTotal 

Open in new window
