Hi,

I have added timeline in portal and it is working properly but I am stuck in one scenario. I have setted timeline for opportunity entity as well as one custom entity.

I have created one custom entity to send email from portal and when mail is sent, that mail is shown on timeline of that custom entity on both platform and portal.

I want to see that mail in opportunity entity timeline also. 

I have changed the rollup value of relationship between opportunity and custom entity from " Cascade None" to " Cascade All".

After that change I can see that email in opportunity timeline also but in platform only. Is there a way we can show that email on portal timeline also? I am not able to see that mail in opportunity entity timeline on portal.

Regards,

Akash
