Your colleague needs to update details of a large campaign and wants to use structured data files (SDFs) to make changes. Before uploading everything to Display and Video 360, they ask you to double-check the files.You find an error. What setting could be causing it?

There’s an SDF with rows for both editing and removing line items.
There’s an SDF for modifying inventory sources.
There’s a single SDF with both line item and insertion order rows ✅
There’s an SDF with 100 line items in a single file.

Why does DV360 throw an error for this?

Structured Data Files in DV360 can only upload one of IO, LI, or Ad group per file. You cannot mix different entity types within the same CSV file.

What does the rule say about it?

Insertion Orders (IOs) and Line Items (LIs) use completely different structures, column headers, and required fields. They must always be downloaded, edited, and uploaded as separate, dedicated files.

Trying to upload a single combined file will confuse the DV360 parser, causing the system to reject the upload or throw a formatting error immediately.

Notes to keep in mind for SDF:

Editing and removing line items together: This is perfectly fine. You can change a line item’s status to “Active”, “Paused”, or “Deleted” within the same file using the status column.

Modifying inventory sources: SDFs have specific files dedicated to inventory sources.

100 line items in a single file: This is well within limits. DV360 allows thousands of rows in a single upload, so 100 will not cause an issue.
