We need to update a custom field on our lots on the inventory number record. We have thousands of lots that we need to update. I can't find that record in the CSV import. Any ideas how to do this mass update?

I have bad news for you....no CSV imports to that record. I'm fairly sure there's no native way to update that other than manually so you'd need to write a script or start splitting up the list between a few people to do manually.

Check if that record is supported by integrator.io (celigo)
