Overview
We have introduced support for adding new Insertion Orders (IOs) along with related Line Items, Ad Groups and Ads to already published DV360 campaigns directly through media plan uploads.
This enhancement allows advertisers to extend existing campaigns without recreating or re-uploading the full campaign setup.

Getting Started
- Use the latest DV360 media plan upload template
- Add a new row for the insertion order you want to create
- Set Request Type to UPDATE
- Fill in the required insertion order level details
- Upload the file and proceed with the usual publish process
Note: Campaign-level information is not required in the row when adding a new insertion order.
