Hi @Chettiyattil Dharman, Mithun ,
Welcome to Microsoft Q&A forum and thanks for reaching out here.
If you are using copy activity, then only upsert operation is available and it is a required field.
If your requirement is to insert only, then you can use mapping data flow activity, in which you have other operations (including insert) supported.
If you have any feature request feedback for copy activity - Dataverse connector, please feel free to log it in IDEAS forum here: https://feedback.azure.com/d365community/forum/1219ec2d-6c26-ec11-b6e6-000d3a4f032c All the feedback shared in this forum are actively monitored and reviewed by respective product owners.
