Hi
I am currently create oData queries dynamically to get data out of dataverse. The problem I have is the name for each field/attribute that you specify in the $select query seems to change betweek LogicalName and SchemaName. Is there a way to determine when to use logical and when to use schema? For example, the following query has to use logical for createdby but schema for CreatedByExternalParty
https://xxx.crm11.dynamics.com/api/data/v9.0/accounts(27cacceb-2a0b-ec11-b6e5-0022484220b6)?$select= name &$expand= createdby ( $select= fullname ), CreatedByExternalParty ( $select= fullname )
If I query the EntityDefinition for each of the above two fields, I can't see any difference between them in terms of metadata:

Any help would be great, thanks.
