I have a set of fields values that need to be made empty again.
I used "Change Data Value" in the flow step and applied the rule - If "attribute1" IS NOT EMPTY, "attribute1" New value _________ .
I did not find "Is empty" for the new value. The attribute1 takes formats like date and string types.
I run the campaign w/o any value (like in the screenshot) but the value did not erase.
