Enable Communication
Between Cognos Portlets
You can enable portlet-to-portlet communication so that
the portlets can interact. For example, you can use this functionality
when you want to navigate published IBM Cognos reports and view
the selected reports on the same page.
This functionality applies only to Cognos portlets and works
between portlets of different groups. For example, the Metric List
portlet can communicate with the Cognos Viewer portlet. One portlet
is a target portlet, and the remaining portlets are source portlets.
The results of actions in the source portlets are shown in the associated
target portlets.
Portlets in different pages can communicate between themselves.
You can enable portlet-to-portlet communication between the following
source and target portlets.

To enable this functionality, you specify a channel name in the
target portlet and refer to this name in the associated source portlets.

Steps
Go to the page or the dashboard that contains the portlets
for which you want to enable portlet-to-portlet communication.
Click the edit button 
in
the portlet title bar.
For the channel property, type the name you want.
The name can contain letters, numbers, and underscore (_) characters,
but must not contain any spaces. For example, Cognos, Cognos_Portlets,
CognosPortlets are valid names.
Note: The boxes where you type the channel name have different
labels in different portlets. For example, Channel, Portlets
using channel, or In a destination portlet.
Click OK.
Repeat the steps for each portlet that you want to broadcast
on the same channel.
Ensure that you type the same channel name.
