configuring the workflow miniapp

[???? ????]

Hello All
 
We have set up a workplace 2.11 system, and would like to use the =
WORKFLOW_INBOX_MINIAPP
 
The problem is that when the miniapp is included in a user's role, no =
data appears in it, apart from a message "No target systems defined for =
workflow inbox for your user"
 
Maybe you can give me a hint where the above definition should be made ?
 
Can I assign more than one system to this miniapp ?
 
many thanks
