Post functions modify data in Jira after a transition is performed. 

The JSU app provides several additional workflow post functions:

To add a post function to your workflow rule:

1. Open a draft version of your workflow. 
2. Select your transition, then select the Post functions tab. Existing post functions for the transition are listed.
3. Select Add Post Function.
   
   
   
4. Choose the required post function, then select Add.
5. Customize the post function as required. You can find details on post function parameters on our dedicated pages for each post function.
