Power Admin's Locations feature allows you to understand precisely how and where configuration elements are used in other elements in Jira. You can analyze the details of the relations between two configuration elements efficiently. For example, you can understand exactly how a custom field is used in a workflow's transition. It might be used in a post function, and Power Admin will show you the transition and exact post-function.
You can review locations for:
custom field used in a workflow, filter, dashboard or agile board
screen used in a workflow
app used in a workflow, filter or agile board
issue type used in a filter or agile board
status used in a workflow, filter or agile board
priority used in a workflow, agile board or filter
resolution used in a workflow, agile board or filter
Locations where an issue type is used in a filter and sub-filter.
There is a Locations column in the Usage table and when you click on the location button there, Power Admin shows you where and how the particular element is used in a workflow.
