Once your Jira instance has multiple workflows, it's not long before you'll find yourself recreating the same post functions (and sequences of post functions) on numerous transitions and projects.
Now with JMWE on Jira server and Data Center, post functions — and post-function sequences — can be created once and reused across multiple workflows. Using the Shared Actions post function, you can create and more easily maintain a single source of truth for any of your commonly configured post functions.
For example, set multiple fields using set field value post functions and then add them to various transitions as one Shared Action, without the need to recreate them again and again. Or configure a post function to send an email, and then reuse it in different workflows.
And because they are post-function based, Shared Actions can also be used outside of Jira workflows with JMWE's Event-based Actions and Scheduled Actions.
In the Shared Actions page (see above), combine one or more JMWE post functions into an action. Then, use the Shared Action post function to add your configuration to various transitions, even in different workflows.
