i have multiple dashboards and i would like to know how can i add dashboard filter by record type? I don see this option in my filter list. I tried added a formula field in my Account & opportunity object but it still doesn't show up in my dashboard filter
The documentation says
You can filter on picklists, lookups, and checkboxes, and on text, numeric, date, and date/time fields.
Guess RecordType isn't any of those eligible field types - it's an Id field in essence by not really treated as lookups.
You can probably create a pickup list that you can stamp different values (with workflow for instance) based on record type, then that can be used as a dashboard filter.
