Creating ViewObject from Entity object

Question

HI,
Is it possible to modify the query of the view object? And I have created that view object from EntityObject.
Regards,
Infy

Hi Arun,
Thanks for your reply. My query has union of 8 different queries. I have created Association between them. But while creating view object, I am getting struck in choosing the association & join type. Can I use expert mode? View object is getting displayed. But when I try to insert any rows, it is throwing errors. My JDev version is, 11.1.2.2.0.. Here is the query:
