2) structure of the plugin crm explorer add steps  and register the image

3)update of attribute of approval status on opportunity entity to test the  scenario.


Create a new field  optionset as approval status on  opportunity entity with optionset values as
 Submitted                  =   100000000 
 Pending approval     =    100000001 
 Approved                 =      100000002

Please make sure the user should have minimum level security role on  opportunity entity 

Entity should be created as access level "user/team".

In my case i have system entity "opportunity entity" which is organisation wide access level.Then i have changed the system user access level to the opportunity in the security roles.

The above plugin code is working perfectly fine..

I hope this helps someone..

Happy CRMing.
