Need to auto create task work item on creation of story worktime type.
Accepted answer
This is something that requires an advisor/follow up action to be written for the save work item operation. I just happen to have done just that for one of our customers.
https://rsjazz.wordpress.com/2016/10/24/using-the-work-item-server-api-to-create-work-items/ describes how to create work items.
https://rsjazz.wordpress.com/?s=Advisor&submit=Search are several advisor examples.
If you want to also create links between the work items, https://rsjazz.wordpress.com/2012/09/20/the-rtc-workitem-server-link-api-linking-to-work-items-and-other-elements/ would explain how.
All blogs suggest to perform the EWM Extensions Workshop as initial step.
