Hi @GRodriguez24,
Here’s how you would approach this:
- Create a custom date property “First call date”
- Create a contact-based workflow that enrolls contacts when a call is logged (enrollment based on ‘When filter criteria is met’ → change ‘Filtering on’ dropdown to ‘Call’ → ‘Activity date is known’)
- Use the “Edit record” workflow action to set the value of “First call date” to the date of the associated call which was first created
- To do so, click in “Edit record”, choose “Choose a date or date property”
- Click into the date field
- Click “Edit available records”
- Click “Add records”
- Choose a record type: Call
- Once added, click again in the “Choose a date or date property” field and select the activity date:
- Create calculation property (time between) that references the create date and the first call date
Create calculation and rollup properties
If you have an existing workflow, please share a screenshot and I can explain why it might not behave as you expect it to.
Best regards
