I have a custom object that will contain the bulk (or all) of 100+ fields for a new lightning app. Also plan to associate the custom object with a new Case standard record at the same time the custom object is created. Currently placing a lookup field on the custom object to the Case record to establish the relationship. Eventually we will implement email-to-case and possibly escalation rules for the Case. Are there any issues with establishing the case lookup from the custom object instead of from Case to custom object? I can't see any loss of Case functionality and we already have many lookup fields on the Case obj so trying to limit that as well.
