I simplified the Express ECO workflow.
start-->submit-->draft changes-->review-->close change
I am using the Express ECO lifecycle :
new--> in planning--> in work -->in review--> released
there is no problem for parts from Preliminary to Released. But when I try to change a released part, for Express ECO "In Work" state, the part does not go the "In Change" state. I think a confusing situation occurs but I can not find the solution.
