I am creating a model driven app. I am creating form in Order entity. I the Order entity, I have a field "Customer" that is a lookup field on " Account entity". The ask is,
If I create a new order form, search for a Customer, then it should auto populate related fields of the Customer (from Account entity) like Address, email, etc.
I know one way to do it Quick view form but the con with that is it's just view only and the fields are not editable. I would like to have, if the address of a Customer is changed, the address field should be editable for the purpose.
Please let me know if there is any way to achieve this.
Looking through your issue here it appears there might be some field security that is getting applied that is preventing you from editing the field. If you take a look at the article below you should be able to remove this and make these fields editable. This might be better suited for Microsoft Customer Support, you could always have them take a look if communities is unable to help you with your issue.
