Hi Martin,
If u look at SalesOrderHeaderV2Entity for example
The entity key is sales order number
This field on entity level is set to Mandatory No
Also this field on staging table is set to Mandatory No even though it's part of the primary Index of the table
So based on that, I concluded that there is no need to make all fields mandatory, but still we can add them to entity key, even though there is a BP that says make them mandatory.
So I just want to make sure that, if I convert the composite entity to a single entity, and put the entity key as the combination of the entity keys of all entities In the composite entity, then that would be ok. Even if not all fields are mandatory.?
Cause as u know each entity in composite entity has entity key...but I can import using composite entity but without filling one of the entities even if it has a mandatory field right?
