How can I add a facility structure parameter into a crystal report with 6 different sub-report?

for example, add location ID, service ID as new parameter.

should add somewhere one place so all 6 sub-reports can use it same time? or have to add these new parameter into each sub-report? these sub-reports are unrelated to each other.

Thanks.

The difficulty is in main page there is no any table or column called 'Location' or 'Service Area', just show below. so if I add Location parameter, how the parameter link to the column?

Would you give more specific detail how sub-report link to main page?

Thanks

Select YES_NO_C as NOT_USED
From ZC_YES_NO
Where YES_NO_C = -1

On main page there
is field called @totalFailedLogin which returns results like 2 or7. each day. parameter link between main report
and sub report does not work. even I tested by remove subreport, this field sill returns data, my question is
where is calculation for this @totalFailedLogin, I can not find from report:


//Total number of user whose failed login time is equal or exceeds the minimal failed login parameter.

Shared NumberVar totalFailedLogin
