Manage Ad Placements Cancel an Ad Placement If an Ad Server provider only has one Ad Placement assigned to it, that Ad Placement cannot be immediately canceled.  First, the Ad Server provider must be unassigned from the campaign by removing its technology assignment in the Schedule grid. Then, the Ad Placement can be canceled. To cancel an Ad Placement, do the following: Open the OneStrata campaign that contains the Ad Placement to be canceled. Go to the Ad Server dashboard for the appropriate provider. If not logged in already, log in to the external integration provider. In the Ad Server grid, select the Ad Placement. Click  Cancel  and then  Save Changes. Optional: If the Ad Placement had previously been linked to an ad server placement, there are two options: Re-upload the Ad Placement to also cancel the linked ad server placement. Unlink the ad server placement. The unlinked ad server placement can be linked to a different Ad Placement. Duplicate an Ad Placement To duplicate an Ad Placement, do the following: Open the OneStrata campaign that contains the Ad Placement to be duplicated. Go to the Ad Server dashboard for the appropriate provider. If not logged in already, log in to the external integration provider. In the Ad Server grid, select the Ad Placement. Click  Duplicate . The duplicated Ad Placement has the same  Name  and  Cost Line ID  as the original Ad Placement, but a different  Ad Placement ID . Choose one of the following options: Continue making changes, like changing the name of the duplicated Ad Placement. Save changes by clicking  Save Changes . Map a Supplier to an Ad Server Supplier Once a OneStrata campaign and an ad server campaign are linked, Ad Placements in the OneStrata campaign can be linked to ad server placements in the ad server campaign. However, delivery metrics cannot flow from the Ad Server provider to OneStrata unless the linked Ad Placement has a Supplier entity that has been mapped to an Ad Server provider supplier. To map a OneStrata Supplier entity to an existing supplier of an Ad Server provider, do the following: Go to the Ad Server dashboard of the desired Ad Server provider. If not logged in already, log in to the external integration provider. Click the  Supplier Mapping  button to open the  Supplier/Site Mapping  widget. In the  Supplier/Site Mapping  widget, do the following: For the desired Supplier entity, click the corresponding  Supplier/Site Mapping  cell to start editing. Enter at least three letters of the Ad Server provider supplier's name. Select the desired Ad Server provider supplier. Click  Apply .
