The position of a post-function in the list of post-functions for a transition is an important factor for its proper execution. When adding a new post-function to a transition, you must move it to the appropriate position, which depends on the type of transition ( **Create** or regular) and the type of post-function you configure. 

- **On the ****Create**** transition**

JMWE post-functions that set the value of a field should generally be placed *before* the **Creates the issue originally** built-in post-function, *unless* they depend on issue links (such as the *Set Field Value from Parent* and *Set Field Value from Linked Issues* post-functions) or on the issue *key* (which is only available after the **Creates the issue originally** built-in post-function runs). Other JMWE post-functions should be placed *after* the **Creates the issue originally** built-in post-function.

:warning: Post-functions that set or access fields from linked issues should *always* be placed *after* the **Creates the issue originally** post-function so that the link is established when the post-function is triggered.

:info: Whenever a post-function is not working as expected on the Create transition, try moving it around the **Creates the issue originally** built-in post-function.

- **On any regular transition**

JMWE post-functions should be placed anywhere in the list *before* the **Update change history for an issue and store the issue in the database** post-function, except for the post-functions that transition issues (see below).

- **Transition Issue, Transition Parent Issue and Transition Linked Issues post-functions**

Post-functions that automatically transition issues should always be placed at the end of the list of post-functions. This applies to the following post-functions:

    - [Transition Issue(s)](https://appfire.atlassian.net/wiki/spaces/JMWE/pages/462127732)
    - [Transition parent issue](https://appfire.atlassian.net/wiki/spaces/JMWE/pages/78056358)
    - [Transition related issues](https://appfire.atlassian.net/wiki/spaces/JMWE/pages/78056510)
