//persistEntity  - which helps to skip validate fields , allow edit and aloow edit on create , mandatory others ,

We can also skip on DMF - data entities - modify target mapping - skip validate field

Please make sure that provide allow edit and allow edit on create, Yes , mandatory No  on on entity level
