Hello, we are having trouble getting a rollup sum for all Activities under Campaign. We are trying to get a count of all activities from regarding. It seems to be possible from this Microsoft article. https://docs.microsoft.com/en-us/dynamics365/customerengagement/on-premises/customize/define-rollup-fields
Below please see our current setup.
Here is a view of the Activities we are trying to roll up to the Campaign.
Here is a ss of Campaign showing the roll up is not working.
Any help would be appreciated.
