In addition to the standard "Meetings Created" card in Atrium that is powered by calendar data (Google Calendar or Office 365), you can also turn on a special "Salesforce (SFDC) Meetings Created" card.
What Data is Used
The "Salesforce SFDC Meetings Created" card uses the "Event" object in Salesforce, and treats the "Created By" field as the "creator" for this card's purposes.
Further, if you'd like, you can specify a field and value or set of values to filter down to.
For example, if you use the "Type" field on the Event object to signify the type of event, and you want to specify that this card should only reflect Events of "Type = Meeting", you can do so.
Also, if you use a different field than Created By to indicate the person responsible for the the creation of the meeting, you can also configure another field to be treated as the "creator."
How to Turn this On
This is an administrative feature, so please get in touch with Support or you Customer Success Manager to help you turn it on.
