Why are users redirected from a Data Change Request page when editing or creating Addresses or Child Accounts?
When a user is trying to edit or create a Child Account or Address on an Account, and they are expected to create a Data Change Request in order to do so, the expectation is that the user will be directed to one of the following VisualForce pages:
If the user is redirected instead to the standard Edit page for Addresses and Child Accounts, this could be due to the Account's record type being included in the CRM_MANAGED_ACCOUNT_TYPES Veeva Message.
Child objects of Accounts will be excluded from the Data Change Request process if the Account's record type is a CRM managed account type.
