List import caused date/time fields to change on existing/merged records

[Hoi_Nguyen3]

Hi Community,

We ran into an issue when we uploaded a list into Marketo. The list contained existing records which were then merged, as expected. However, date/time fields that weren't even on the Excel sheet were then being updated. See attached screenshot.

I read that any imported date/time fields are treated as Central Time and our organization is using Pacific Time. (See article: Import a List of People - Marketo Docs - Product Documentation )

However, I'm not sure why this would matter because we aren't importing any date/time fields.

Does anyone know what may be happening?

Thanks,

Hoi

Hi Hoi,

What are the fields that are updated ? Look at the activity log and check when and from which source the fields were updated. Provide some screenshots of the detailed activities here if you need help.

Apologies. I thought I had uploaded the screenshot with my first post. See below:

Again, we definitely did not include a column for "Created DateTime" on the Excel sheet. It just updated seemingly automatically.

Hey Hoi,

My understanding of merged records is that MKTO should honor the oldest value it would have, but based on this field being a custom field, i'm not sure how MKTO resolves conflict on an import. I would double check the file you imported to ensure it doesn't have this field or another date field included in the file that's import alias was auto-mapped to this field. Outside of this, maybe double check "field blocking" for this record to make it unchangeable via import.

Sincerely,
