I want to be able to create a object of another Collection, but I don't know how to create a collection object in business logic. Can anyone please help. thank you.
You can use insert/save/update methods in collectionAccess module in BL to achieve this. The details about this module are available here: http://devcenter.kinvey.com/rest/reference/business-logic/reference.html#collection-access-module
You can check the BL documentation available here:
