Set the participant as required at the time of promotion request creation in windchill
Version: Windchill 12.0
Use Case: Currently, I am able to create a promotion request in windchill without selecting any members from the participant list. I want to add up a condition in the promotion creation page, when a user miss to select the required participant from the member list it pops up an error stating that the required members are not added, and the promotion request cannot be created without them.
Description:
When the promotion is created with this issue, the workflow gets stalled when the task is to be created for those missing participant and it cannot be recovered back. User needs to create a new promotion request to proceed further with.
I want to implement a way in promotion request creation where user is notified or there is some pop-up error/validation that checks when the user fails to add the appropriate users in the member list.
Is there a way we can add this validation or customization to our windchill?
