homepage processor My messages filter by User status

Hi,

For our processor of ITSM (Solman 7.1 SP8),we have tried to undisplay the message with status "confirmed" or "withdrawn" with the Business Role.

unfortunately it does work, the ticket (with status confirmed or withdrawn) still appear in the homepage of our processor in "my messages"

We would like to hid ticket with status "confirmed" (closed) or "withdrawn"

Help would be grateful.

Thomas
