This type of read-only custom field has a value which is dynamically calculated from a custom math/numeric expression.

It can be used to obtain a numeric value depending on the value of other fields in the current issue or in any other issues (linked issues, sub-tasks, epics, stories, JQL selected issues, etc).


Configuration

Configuring a calculated date-time field is straightforward. You have to configure a valid parser expression, which will "calculate" the output, and optionally a custom display format.


Create a new Calculated Date-Time Field (by JWT) custom field and name it properly

Providing a description will help you to identify what the custom field does but this step is optional



Math/Numeric expression

Add a valid parser expression which will "calculate" the output.

Usually field codes will be used for this purpose.

%{issue.links.count} #This example simply returns the number of linked issues.


The result of the calculation must be a valid number. 



Display format

Optionally choose a custom display format format. This is extremely useful to enhance usability for end users.
