Post Function to set due date from another filed plus 3 days

[Jeff Meyer]

I have a project that auto creates additional tickets in other projects when a ticket is opened in project 1 (using post function "Create new issue"). I have been asked to set the "Due Date" field (in project 2) from the "Target End Date" field (in project 1) and add 72 hours or 3 days to it. I have been able to set the "Due Date" field (in project 2) to the "Target End Date" (from project 1), but not sure how to add the additional time  (72hrs or 3 days) to the "Due Date" field in project 2.

Thanks

Jeff

Hi Jeff,

your post-function "Create new issue" has to come from an app that is installed in your Jira, since it is no standard Jira post-function. Can you tell us which one you are using, so we can help you with your problem?

Best,

It looks to be from Jira Misc Workflow Extensions (JMWE)

Then, you can use the "Set new fields" functionality in the post-function to set the due date plus three days using the following Nunjucks expression:

{{ issue.fields["Target end"] | date('add' , 3 , 'days') | date("YYYY-MM-DD") }}

So it looks like this in your "Create issue(s)" post-function:

Let me know, if this works for you :)

Hi Ramin,

Thank you very much, that worked for what I was looking to do. 

Thanks for taking the time to help me out with this.

Hi Jeff - Welcome to the Atlassian Community!

Have you thought about using an automation rule instead of a post function in the workflow? Then it can be used more universally.

I think you're looking for the "Date plus unit" function.

...and not for nothing, you might add "BusinessDays" instead of just "days."  :-)
