how to pass a main report group total to a subreport ?

[lsantos]

Hi,

I am using Crystal Reports V7 and have a report + sub-report totalling question:

How can I pass a main report group total to a subreport so that I can provide: subreport group total = ((main report group total) – (subreport group total)) ?

Suggestions will be very much appreciated.

Hi LS,

You need to store the subreport group total into a shared variable like:

shared numbervar grouptotal := Sum({LYsales},{Grouping});

Then in the main report declare the same variable:

shared numbervar grouptotal;

Then add the main report figure:

grouptotal := grouptotal + (main report grouptotal)

local variables disappear after it is used.

global variables exist throughout the report and can be accessed anywhere in the report.

shared varaibles are like global variables except subreports can access and modify values as well.

Hope this helps,
