Hi Ralf,

Thanks for the suggestion and I will verify marking as deferrable constraint.

And I followed another approach of storing the details in a join table, I am 
encountering a null pointer exception while saving the data. Displayed all the 
objects in the context by using "context.insertedObjects()" and I can see all 
the objects and data in console.

Can you suggest me where I am going wrong.

Regards,
Pavan.
