You can edit the default query in the Application Source Qualifier by editing the transformation properties. This includes editing the transformation settings or changing the connected ports in the transformation.

When you edit the Application Source Qualifier, the Designer includes these settings in the default query. The PowerCenter Integration Service uses the default query to create the extract query for the session.

You can also override the default query with the Extract Override option. When you enter an Extract Override, the PowerCenter Integration Service uses the defined extract override.
