Behaviour of Activity Clipboard of Interaction Record

Hi everyone,

I have observed a weird behaviour of Activity clipboard in CRM Interaction Center. Below are the steps I followed:

1. Confirmed the account in the Interaction Center. Opened Interaction Record
2. After performing my actions in  the Interaction Record, saved the Interaction record by clicking the "SAVE" button on the Interaction Record screen.
3. Closed the browser(without clicking on END button on the IC).
4. Opened CRM WebUI and opened this new Interaction Record, I do not find any of the items in the Activity Clipboard. It is completely blank with no items.

But if I click on "END" button on the Interaction Center  and then check the Interaction Record later through Inbox , I can find the items in the Activity clipboard. I need to understand if this is a standard behaviour of CRM Interaction Center that clicking END button is mandatory for saving the Activity clipboard items into database? Or Do I need to apply some SAP Note to fix this issue?

Please suggest.

Thanks,

San
