Dependent Change Tasks

[ybagul]

Currently all change tasks within a change notice start simultaneously. I am looking for a way to make them dependent so as to start one after previous is completed and approved. So is there a way to add this dependency in change tasks with any configuration or customization?

This is available OTB in Windchill 10 (requires ProjectLink to be installed).

For 9.x, I don't know of any way other than some workflow trickiness.

Thank you Mike. We are currently on 9.1 M40 and there are no plans to upgrade to 10 as of now.

I looked at synchronization robots in work flow. That seems one potential approach to have dependent change task.

I was finally able to achieve this. Here is how.

1. Create an integer attribute 'Sequence' on the change task object

2. Modify Change Notice Workflow

a. Grab all change tasks within change notice, iterate through them based on Sequence attribute and set state to implementation manully

b. Modify synchronization robot to listen/fire for state change event on this change task

3. Modify Change Task workflow

a. Modify synchronization robot to listen/fire for state change event of PBO (Change Task)
