If you are using JSU on Jira Cloud, see our JSU Cloud [documentation](https://appfire.atlassian.net/wiki/spaces/JSUCLOUD/pages/12517909). ## Essential post functions Jira transitions include essential post functions that are executed in a specific order. You can’t delete or move these post functions, but you can place JSU post functions in between. When adding JSU post functions to a transition, it is important to position the post function with respect to the essential post functions. Learn more about Jira’s essential post functions in Atlassian’s [Advanced Workflow Configuration](https://confluence.atlassian.com/adminjiraserver073/advanced-workflow-configuration-861253591.html) documentation. ### The Create transition The Create transition is an issue’s first transition and does not have a source status (only destination status, usually Open). If you add a post function to the Create transition, you should generally position it **before** Jira’s *Create the issue originally* post function. > ℹ️ **JSU exceptions** > ℹ️ > ℹ️ - [Clear Field Value (JSU)](https://appfire.atlassian.net/wiki/spaces/JSU/pages/12682442): If used to clear a label after the issue is created, place it **after** the *Create the issue originally* post function. > ℹ️ - [Update Any Issue Field (JSU)](https://appfire.atlassian.net/wiki/spaces/JSU/pages/12682426): Must be placed **after** the *Creates the issue originally* post function. > ℹ️ - [Create a Linked Issue (JSU)](https://appfire.atlassian.net/wiki/spaces/JSU/pages/12682165): Must be placed **after** the *Creates the issue originally* post function. ### Any other transition (not Create) If you are adding a post function to any other transition, position it anywhere **before** the *Update change history for an issue and store the issue in the database* post function. > ℹ️ **JSU exceptions** > ℹ️ > ℹ️ [Follow-up Transition (JSU)](https://appfire.atlassian.net/wiki/spaces/JSU/pages/12682621): This must be the final post function for a transition. Position it **after** **all** other post functions. ## Change the order of JSU post functions You can reposition a JSU post function in your draft workflow. Position your cursor in a post function row, then use the up and down arrows to move the post function to the desired position. ![List of post functions configured for a transition as shown in the draft workflow.](media://2aeb387a-4220-4a50-a55f-f1431a770452)
