Select a subreport in your
primary report, and go to the
"Properties" view.
In the Subreport area,
click the
Subreport
Links property.
Click the button at the
end of the
Value field.
The Subreport Links dialog box
appears.
Click
New, and select the field you want to use as a link field
in the primary (containing) report from the
Main
Fields list.
Crystal Reports tries to
make a match between the field you chose and a field in the subreport.
To change the subreport
field that the program chose, click that field in the
Subreport
Field list and choose a different field.
The two fields are added as a link
field.
Repeat steps 4 and 5 for
each additional link, as desired.
Click
OK.
When you run the report, the program
will coordinate the data in the primary report with the data in the subreport.
