I am trying to create a custom event field. As you probably know, the way to do that is to create a custom activity field since an event is a special type of activity.
I want to subtract an event's start time from the end time so I can determine its length.
However, when I build my formula, I cannot choose the event start/end fields. All I see are activity fields, not event fields.
What I am looking for:
But when I build my formula, I cannot use these names. I get Error: Field EndDateTime does not exist. Check spelling.
I get this whether I try
EndDateTime - StartDateTimeor
EndDateTime - ActivityDateTime
So why cannot I use the event fields in my formula? What is their real field name? This is frustrating.
BTW this relates to another question I asked here.
Lastly, I found the Salesforce field name reference and it does list the fields I want to use.
