Some of our users want to use Data import for updating data. While doing so, they routinely need to set values of some fields to blank. From what we know, that’s not possible as of this writing.
Is there a way/workaround to do this? Is there a reason why this cannot be provided? Or can it be provided with some known quirks?
select the documents by ticking check box on the first column in the grid
click Actions->Edit (upper right corner), in the popup window, select the target field, leave the value field empty, click the update xx records button.
option2: python script workaround solution
define a valid special value for the target field, e.g Brand D for brand field in Item,
in import file, assign the special value which will be set as empty after import
in python script, if special value, then set the field as empty string
