Service desk message view from ECC

Hi

I have following queries regarding service desk in solution manager.

1. Do user need to login into solution manager to see his message status or can he directly see it from ECC.

2. When a message is created through satellite system support message should display TCode in support message.

3. In service desk mail (New message/ )attachment of message is not appearing. Currently it visible in solman ticket, As per requirement attachment of message should also be mailed.

4. while creating message end user should not login to solution manager. Communication between ECC and Solman has to automatic

5. Users should have reference to earlier messages through ecc.

Thanks

Regards

Mahesh Kumar
