Filtering is a great way to look closely at the data you have in your Directory.
One feature that is useful can determine whether or not businesses have any Activities added and if they have People associated to them.
How can I do this with Activities?
In the Businesses table scroll along to the Activities Column
Click on Filter
Click on one of the options: Has activities, Does not have Activities, All.
You can maximise your search result by including and excluding words
Close
Can I do the same for People?
Yes if you reset the Filters, (via Layout, Reset Filters) you can scroll along to the 'Other People' Column and follow the same steps as above but with this Column instead.
For example; If you want to look into Businesses that do not have Activities and do not have Other People added, you can do so by filtering both Columns. You can then save this as a Layout.
