The error message indicates that you are trying to insert data into a read-only column named "position_id." The most likely cause of this issue is that the destination table has a column that is marked as read-only, and you are trying to insert data into this column.

To fix this error, you need to modify the destination table and make sure that the "position_id" column is not marked as read-only. You can do this by using SQL Server Management Studio or any other database management tool that supports table modifications.

Here are the steps to modify the table:

Open SQL Server Management Studio and connect to the database server where the destination table is located.

  1. Navigate to the database that contains the destination table.
  2. Expand the "Tables" folder and locate the destination table.
  3. Right-click on the table and select "Design."
  4. Locate the "position_id" column and check its properties.
  5. Make sure that the "Is Identity" property is set to "No" and the "Read-Only" property is set to "No."
  6. Save the changes to the table.
  7. Re-run the SQL Server Import and Export Wizard.

By following these steps, you should be able to fix the error and successfully export data from one database to another.
