If you’ve created project fields for your project you can apply them to issue types and specify if they are mandatory.
Adding project fields to your issue types is straightforward - but you do need to create them first.
If you need to edit a Project field associated with one or more issue types, we recommend creating a new Project field instead of editing the existing one.
Project fields can only be added from the Aconex web application, not from the mobile app.
Field supports all Project Field types: single-select, multiple-select, text, text area, number, date and yes/no.
Newly created or edited project fields may take up to 3 minutes to be available in Field.
