Data Transfer v2.0: FAQ

This document provides answers to some frequently asked questions.

What information is in the filename?
Each file name will have a string of numbers, for example:
dcm_account1234_impression_2016022601_20160225_234912_218211994.csv.gz
  • 2016022601 is in YYYYMMDDHH format. This is the UTC hour for events in that file (hours are numbered 0 to 23).
  • 20160225_234912 is in YYYYMMDD_HHMMSS format. This is the time the report was generated in local account time (DCM and unified) or EST (DBM only).
  • 218211994 is the file ID.
How do I know when all files are delivered?
For each day there are:
  • 24 click files (hours 0-23).
  • 24 impression files (hours 0-23).
  • 1 activity file.
  • 21 match tables.
Clients with custom configurations may have different numbers.
What if I encounter duplicate files for the same date and hour?
This can happen. When more than one file has the same date/hour stamp, use the one with the latest minutes / seconds, based on the filename timestamp.
I think some of my data is incorrect, what can I do?
Contact your DoubleClick support representative with information about the problem. If data seems to be missing, provide details about which hours are missing, and files that aren’t accounted for.
How do I find out what's been deprecated in v2, or moved to match tables?
See the migration guide for information on mapping from v1 to v2.
