I would like to talk about an important Microsoft CRM design setting: Cascade Relationship Behavior.
Scenario: What happens to the Account’s child records (Contacts, Opportunities, Activities, History, etc.) ownership if we reassigned the Account to another owner? If I have a CRM account record "ABC, Inc." with an initial ownership of "Owner2" and I then reassigned the "ABC, Inc." account record to "Owner3" – what effect does this have on the ABC, Inc.’s child records ownership?
Answer: Under the default Microsoft CRM 4.0 (OnPremise) and CRM Online setting – they will all be reassigned to "Owner3".
Reassigned to Owner3:
All ABC, Inc.’s child contacts are reassigned to "Owner3":
Same for all of ABC, Inc.’s child activities – they are all reassigned to "Owner3":
Same for all of ABC, Inc.’s child history – reassigned to "Owner3" and so on for all other ABC, Inc. child records
An important note is that for CRM History records (activities that are completed) or any other "completed" record types such as CRM Opportunities, Leads, Cases, etc. – we should keep the data intact and not change the Owner info since it should be considered "historical" data.
So, if this is not the desirable initial setting, how do we change it?
Answer: This setting can be updated under the "Relationship Behavior" section in the Account customization (CRM Client >> Settings >> Customization >> Account >> select the child record type under "Related Entity"):
Under the "Relationship Behavior" section, change the "Type of Behavior" from "Parental" to "Configurable Cascade", select a different action for the "Assign" cascade behavior. The default is "Cascade All".
There are four actions to select from: "Cascade All", "Cascade None", "Cascade Active", and "Cascade User-Owned". "Cascade None" is the most conservative.
Review the Assign Cascade Relationship Behavior for other child record types and select the desired behavior setting. Be sure to save and then publish your customization afterwards. Repeat this for other CRM entities such as Contact, Lead, Opportunity, Case, etc.
