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 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.
