How to copy assignee value from previous assignee?

[sai chinamuthevi]

Hi team,

we have a transition called unit testing--->Sit---->To Do.

i created a post function when the issue is transition from unit testing to sit default assignee should be something called "A".

Now the assignee of the issue is A.

but when we transitioned issue from sit to To Do the assignee  should  be previous assignee who is before A.

how can we do this ?

You can store the previous assignee in a (hidden) custom field and use an automation (or post function) to copy this value back into the assignee field.
