If you turn on the attribution window for Facebook during the extraction setup process,

this setting will dynamically create columns with the selected attribution for each metric with a value (not Null).

If there are too many columns and it is inconvenient to work with them, then you can disable useless metrics showing:

1. Open the related data table settings and deselect unnecessary metrics.
2. Enter the attribution to the search field in the Available metrics section
3. Deselect all results, and then select only those metrics you need
4. After this, deselected metrics will not be displayed anywhere.
