When mapping Created by and Owner fields during a migration using KingswaySoft, i keep getting the following error.
Error: Failed to set field 'ownerid' value to 'Person A' for entity 'Custom_Entity' (field type: Owner, value type: String). System.Exception: Duplicate entries found when populating lookup cache for text field 'fullname' of 'systemuser' entity. Duplicate text value: 'Person B' (SSIS Integration Toolkit for Microsoft Dynamics 365, v9.1.0.6620 - DtsDebugHost, v11.0.6020.0)
I'm mapping the OwnerIdName field in CRM 2011 On Premise to the OwnerId field in D365 Online using the text lookup (see below) this worked when transferring cases but fails when i transfer the custom entity records.
