Child object rollup
Hi WF Community,
Does anyone know if it's possible to create a custom calculated field on a parent object (Project) that would rollup (sum) the values of a custom field from a child object (Task)?
Example:
We have a custom field called 'Total Invoice Amount' on the Task object. I wanted to create a custom calculated field on the project object that would display the sum value for any Total Invoice Amount values on a projects tasks.
I tried creating a new custom calculated field on the Project object like this: Task.{Total Invoice Amount}, but it doesn't like that and won't let me save it.
Any ideas?
Thanks.
Nick
