Configuring the WsActionInboxConnector 
The WsActionInboxConnector of the consumer system connects to the ActionInboxConnector of the provider system and provides KM Recent Notifications in the Universal Worklist (UWL) Notification tab, checked-out documents under Tracking, and documents for approval under Tasks. The notifications, tracking, and tasks are taken from the provider system.
Note
We recommend that you use this connector only in a federated portal network (FPN).
Before you configure WsActionInboxConnector you have to meet the following prerequisites:
You have the System Administrator portal role assigned to your user on the consumer system.
You have a user with the appropriate authorizations in SAP NetWeaver Application Server Java on both the consumer and the provider systems.
Register the provider system as an item provider for the UWL.

Create and deploy the WsActionInboxConnector proxy on the consumer system.
More information: Creating WsActionInboxConnector Proxy
Specify the authentication method for the connection between the consumer and the provider systems.
More information: Specifying the Authentication Method for the Connection
Configure the provider system to accept logon tickets from the consumer.

Repeat the above procedure for every remote system you want to connect to.
KM Recent Notifications, checked-out documents, and documents for approval from the remote provider systems are shown in the UWL of the consumer system.
Note
Make sure that you set a higher value for the Timeout Value for the Connected Systems in UWL service parameters, to avoid possible connection timeout errors in the system connection status.
