comparing 2 fields from 2 different issue types

[Chad_Lei]

suppose there is a field named APPLECOLOR

I want to check issue type A's APPLECOLOR value with issue type B's APPLECOLOR in a post function after reaching a certain status in issue type A's workflow, and if it's true then change issue type B's DATE field to issue type A's DATE field. I'm thinking 'Set field value (JMWE add-on)' post function is the way to go, but I'm open to other suggestions or the correct way to do it!

code version:

if A.APPLECOLOR == B.APPLECOLOR 
    then B.DATE = A.DATE

Jira Workflow Toolbox App can do this sort of thing. Hopefully you're on Server or Data Center :)

any way to do it through a post function? or something for free? or is it not supported currently?

[Dave Theodore [Coyote Creek Consulting]]

You would need to use a post function with Jira Workflow Toolbox in order to do this.

Built in workflow functions have no capability to perform arithmetic functions, so you will need a 3rd party App of some sort.

I see. I'll check that out in the meantime, but hopefully, someone can think of a workaround without a 3rd party app

thanks!
