Configuration of Preconditions

Preconditions allow you to execute a post function under certain circumstances only. This allows you to create complex behaviour on your post functions, enabling you to let Jira perform more work for you.

In JSU Cloud, preconditions are a part of the post function.

Choose your Precondition

Click the "Add Precondition" button and insert the precondition you want to evaluate. For more details, take a look at the Value Field Precondition and the JQL Precondition.

Combine several Preconditions

You can insert multiple precondition and combine them using AND, OR, AND NOT, and OR NOT operators. AND NOT and OR NOT are not equivalent to NAND and NOR, they only negate the result of the precondition before combining it with the previous result. They are evaluated sequentially, combining the result of the previous precondition with the result from the current one. Parentheses to configure precedence are not supported.

You can also rearrange the precondition by dragging the handle on the left.

You can also disable the precondition by unchecking the enabled flag next to the delete button. This will leave the precondition in your configuration, but it will be ignored.

The Post Function Side

Your post function is always aware of the preconditions you configured. However, you still need to select whether you want the precondition to be true or false for the function to be executed.

Example

Say you want to tell the user to break up a large story into smaller stories. You could do this by creating an Update Any Issue Field post function and setting the precondition as described:

• IF Original Estimate >= 2d
• OR Story Points > 8
• AND Issue Type = Story

In other words, if you have a time estimate greater than or equal to two days or the number of story points exceeds 8 and the issue is a Story, then you want to execute the post function.

In the post function you update the issue by adding a new comment. After you save, the overview should look like this:
