Hi there,

I would like to create a formula field in activity (Task) that displays value from a field in opportunity that it is related to
For example: display the opportunity name that it is related to

I am not sure how to do this (or if this is even possible)

I know you can reference Account but i wonder why it could not refer to opportunity
I found out that you can use WhatId to get the ID of account or opportunity

Now i am thinking if there is a way to reference Opportunity the easy way or maybe if we can do a look up using the opportunity ID that we can get using WhatId

I hope someone can enlighten me

Thanks
