Update cuatom field of parent task when values of same cuatom field in its subtask are updated

[rahuldanwade]

Hello all my requirements are as below

I have two custom fields say in a parent task (for the time being consider type of these fields to be Text field )

1.fieldA

2.fieldB

All sub-tasks which will be produced from this task will be having same custom fields.

Now whenever any one of above fields from any of the sub-task value is added it should also update same value in parent task field as well.

for e.g. :-

Parent issue has 3 subtask

if I add value to fieldA in subtask-1 ,subtask-2, subtask-3

it should also be added(all three values from sub-tasks) to parent task's fieldA( text box) with Comma as a separator.   

Is it possible in JIRA

any post function , custom groovy script needed to be written for this.

appreciate your support.

Hi Rahul,

You are right to assume this would be a scripted action, and it is relatively easy to implement as such.

You would implement the script as a post-function so that whenever the issue is transitioned it would check the following.

1. Is this a sub-task or a task?
2. If a sub-task is the value already present in the parent custom field or not?
   If a parent task does the value contain the value from all the sub-tasks? 
3.  If the value is missing then update the parent task to include it.

The interesting part to the coding is deciding what to do with values that were previously in a sub-task but have since been updated. It is not sufficient to just delete them from the parent as they may apply in another sub-task. So the  approach I would take is to identify the parent issue, then loop over all the sub-tasks updating the values at that point removing the original values before the start of the loop.

I hope this helps clarify your requirements.
