Error in importing Data SQL Server

[vishnukantsharma702]

While importing the data in the SQL Server, I am getting this error.

I am not able to solve the error after trying so much in the internet and youtube also.
Can anyone help in solving me this error.

Could you post target table's structure and some source data?

Hello @vishnukantsharma702 The error message is stating that the column named "InvariantName" is defined as UNIQUE so looks like your source data contains duplicate values. You can either clean up the duplicates or remove the constraint Regards Javier
