show activities related to custom module also in account

hi,

we have a custom module (lets call it A).

A is related to accounts and related to activities. So in A in the DetailView you can create Activities. The parent_type of such activities is set to A.

What i want ist that i can see such Activities created in A are also visible in the DetailView of the account, that A is related to.

I know that in this account only activities are shown that have parent_type = Accounts and parent_id = accounts.id.

Any ideas how this can be solved?

or maybe other example without custom Module.

if i add a Meeting to an Opportunity we want to see this meeting also in the Detailview of the Account that is related to the Opportunity.

Hey @lenz1979 , I m trying to achieve the same , Are you able to solve it?

Thanks for your help in advance

Regards,
Sravani
