Can't use Database Table Destination object when either single port is selected or multiple ports => insert is selected

Trying to write a csv file to database. I’m creating a new table in the properties window and selecting either single port or multiple ports and then selecting insert results in this error:

> DatabaseDest2: At least one matching key field must be specified to enable database update, delete, or upsert.

The error points towards not having a primary key but I’ve defined it already as can be seen in the screenshot:

Hi Taha,
Please check if you have selected a field for matching database record on the second page of database destination properties.
