I'm new to Dynamics CRM and I'm facing the following problem. I have a clean on-premises Dynamics CRM 2011 deployment and I would like to have accounts and contacts shared between all my business units. However some business units require specific new fields to be created on accounts and contacts, and these custom fields should only be seen by that business unit. The standard out of the box fields for this two entities should be available to every business units.
Other business units should be able to see what we call a public view of this two entities (accounts and contacts) but they might also have their own reserved fields within the accounts and contacts entities that should be kept unavailable to other units. What should be the most efficient way to achieve this goal?
I was considering the creation of custom entities for each business unit specific requirements, but soon I've faced a situation in which I was trying to have in the new entity form lookups created, not only to the accounts and contacts, but also to specific fields of the accounts and contact entities (which is something I couldn’t find how to do). I’m not sure if I was clear in question, but any help pointing me the right direction would very appreciated.
