I have noticed that SalesOrderHeaderV2Entity got deprecated and released new entity SalesOrderHeaderV3Entity when upgraded the version from 10.0.35 to 10.0.36. All of sudden post upgrading to 10.0.36 import and export operations not working on Sales order headers v2. Looking forward for Microsoft to take up notice of this request and provide a fresh new document detail lists of data entities marked as obsolete on every new Finance and operations release version.
