I'm doing exercises on salesforce trailhead and created simple custom field of type Formula:
- field is created on Case object
- Formula Return Type: Number
- Decimal Places: 0
- Formula itself: TODAY() - Account.LastActivityDate
- Blank Field Handling: Treat blank fields as zeroes
This should give me number of days since last activity on account. On case page I see the field, but it shows me blank value.
Is it a bug or I'm doing something wrong?
I'm on developer edition.
