Hello,



I would like to display inside the gantt bars, the name of the task (easy) and the name of the summary task.
As I will have a lot of repetitive tasks, with the only difference will be the summary/group task, I would like to be able to see this difference on the gantt chart.

I already tried by creating a custom field, with formula but then I'm not able to get the Summarry task name in my formula. I would like to have something as the following idea, but [SummaryTaskName] doesn't exist.

IIf([Summary]=Yes;"";[SummaryTaskName] & " - " & [Name])

Can someone help me ?
How to retrieve the summary task name in a formula ?

Thanks for your help
