Metadata transformation provides option to exclude variables from the import, that you don’t want to show in your reports. You can also select several variables and inactivate them with the same process. This option excludes the variable and you will not be able to see it in the project. There are other options in different Dapresy functions to inactivate a variable if you already imported it.

  1. When metadata transformation opened place the cursor on the variable, then right-click.
  2. Press Inactivate variable and small X sign in a circle will mark variable as inactive.
  3. To activate the variable press Activate variable. The sign will disappear.  

The performance of your project (loading and reading in data) will be slower if you use and import the variables which are not needed or required for your project.
