Authorization Object for Service Desk Messages

Hi everybody

I need to make sure that Service Desk messages assigned to a certain support team are only viewable by this specific team but not by all.

Unfortunately I did not find a possiblitiy to narrow down this possibilty using the standart role SAP_SUPPDESK_DISPLAY.

When I was searching this forum I fond the following post: Authorization for Service Desk Messages

Unfortunately this does not really help me since the user is still able to search and view all messages.

I already thank in advance for your help!
