When you have connected Elements space with your Salesforce org, you can check where any field is being used and how much it is being used.
Just select any child node to "Fields" parent and select the "USAGE" tab on the right panel.
Where field is used?
You will first see collapsed lists of items that are using this particular field grouped by type. Click on the ">" to expand the section to see the individual items.
Items that use the selected field will be listed with a hyperlink icon to Salesforce setup for that item. When you roll over the listed item you will see a popover with the key metadata:
You can check whether a field is being used by:
- Apex Classes
- Apex Triggers
- Approval Processes
- Email Templates
- Field Sets
- Formula Fields
- Global Actions
- Page Layouts
- Process Builder Workflows
- Sharing Rules
- Validation Rules
- Workflow Field Updates
- Workflow Rules
Note on Apex usage
There are just a few apex structures for which we currently do not support the field usage information, these are:
- Nested SOQL
- Chain of lookups in SOQL
- Dependency usage from other classes
- SObjects and methods from SObjects
- Reinitialization of variables to a different type
- When a Developer org has a namespace but uses field/object without namespace
- Switch-case statement (for apex classes with version 43.0 and more)
How populated is my field?
Below you will see the bar chart showing you % population of that field. On a weekly basis (if you turned on the automatic sync) we fetch data for the last 10,000 updated records for each object. This allows us to calculate & display the % population for all fields for all objects. If you would prefer to see the full % population for the last 1 000 000 updated records just fetch the data manually using the Update text button.
From an object you can see the % population for all fields. Select the "USAGE" tab as you did for fields. You will see a bar chart showing you the population of the first 20 fields in the object. Click "View all" at the bottom to see all the fields in the object. You can also filter this bar chart by types of fields (standard, custom and system - the last of which are turned off by default).
