Hi All

Business Use case:

Incident Quick search report,  result should be based on logged assigned either Incident/Tasks wise.

incident had outer join relationship with tasks. So, multiple rows are displayed, we used Group_Result  /Aggregate Function(count(distinct(incidents.i_id)) to hide/remove rows. only unique values are displayed on report  but unable to open and view incidents.
