Hi Experts
In campaign flex ui, there is a tool bar button Generate Model . It pop ups the fields to enter the Job Name and schedule time. It is leading a job to start & getting cancelled finally.
This same pop-up comes when right click on Target Group icon, and clicks on option 'Generate Target Group'. here also fields are there to enter the Job Name and schedule time. It is also leading a job to start & getting cancelled finally. 
If I save the Target group and go back to campaign main page and START the campaign execution with Job Name and Schedule Time. Here Job is getting created and ending with Finished status.
Why and What is use of other options(Generate Model/Generate Target Group) available in the Segment Builder's Flex-UI. Can you please help here.

Hamid
