As part of the Google DCM export, a new standard custom column has been added called "DCM Placement Compatibility".
This field will be available in your list of Inactive media plan custom columns.
Click on Show to add the field to your media plan.
The field will include the applicable values that can then be selected in your media plan.
When you export the DCM Placement Import export file from Bionic, this field will be automatically included in the output.
