Allow Blank Override

Hello,

I am trying to get a better understanding of "Allow Blank Override" for imports. What resources do you recommend?

Thank you!

Hi @GilbertH ,

I would start with the Import Module Overview Article. It explains the following:

If you choose the Update or Upsert import type, you have the option to Allow Blank Override. This box is checked by default.

If checked, this feature will always update even when the source is blank.
- If your source has a blank value for First Name, and your CRM has James for first name, the final record after import will have a blank value for first name.
If unchecked, this feature will always update unless the source is blank.
- If your source has a blank value for First Name, and your CRM has James for first name, the final record after import will have James for first name.

Let me know if you have additional questions.

My screen does not show the checkbox or "allow blank override" option on an Import job of update or upsert.

Hey @brioh - This feature was included in the 5.25.8 release so it has been quite a while since it was rolled out. Please reach out to support@validity.com if you are on DemandTools V version 5.25.8 or later and still not seeing the option.
