Hi!
On Contact entity I have field called parent account, which is a lookup field to account record. The field is on status business required.
Now we are implementing Dynamics 365 Marketing and creating newsletter form, form where people can join to the subscription list (a marketing list).Marketing form type is landing page since we need to create contacts from subscribers.
When publishing marketing form, we get a warning: " To Create a Contact the Parent Customer (xxx) field should be included in your form and marked as required. " Since field is lookup field is not an option when creating marketing form field, we cannot add this field to the form.

What would be the best approach to this? Does this warning cause technical malfunctioning? Our customer is planning to manually add contacts an account when new contacts are generated, so there isn't any business case problem.
We would not want to remove the business required status from the field.
