You want to change the end date for multiple line items within your Display & Video 360 campaign and plan to use structured data files (SDFs) for bulk editing. What's the first step you should take?

Analysis of Correct Answer(s) The standard workflow for making bulk edits using Structured Data Files (SDFs) always begins with downloading the relevant data from the Display & Video 360 interface.

• This initial download provides a correctly formatted file containing the most current settings and, most importantly, the unique IDs for each line item you wish to edit.
• Working from a fresh download prevents errors, ensures you have the correct column structure, and confirms you are modifying the correct entities. Therefore, downloading the SDF is the essential first step before any changes can be made offline.

Analysis of Incorrect Options - You should upload your updated file to your Display & Video 360 account: This is the final step in the process, performed only after you have downloaded and edited the file. - You should make changes within your Display & Video 360 account: This refers to manual edits within the user interface, which contradicts the question's premise of using SDFs for an efficient bulk change. - You should make changes to the structured data file directly in Display & Video 360: This is not a function within the platform. SDFs are files (e.g., .csv) that must be downloaded and edited offline using spreadsheet software.
