Sub Report and passing variables

[DougNaf]

I have a main program and a subreport and am able to pass a variable and results from the subreport to the main program and it works just fine. The variable is placed on a detail line (main program). The problem i am having is i would like to insert a group total for the variable, but am not able to select the option for a inserting a summary for the group. Does anyone have suggestions? I am using version 9.

Thanks
Doug

Use a variable in the main report to accumulate the shared variable. Let's say your shared variable from the subreport is x.

//{@reset} to be placed in the group header:
whileprintingrecords;
numbervar y := 0;

//{@accum} to be placed in a detail section below the one in which the subreport is executing:
whileprintingrecords;
shared numbervar x;
numbervar y := y + x;

//{@display} to be placed in the group footer:
whileprintingrecords;
numbervar y;

If the subreport can return nulls, you should also have a reset in the main report for the shared variable, in a detail section above the one in which the subreport is executing.
