Dear SAP,
we´ve created several z-fields in contact profile. Via data-upload you can of course bring values into that fields (in template for data upload the z-fields are included). It´s also possible update the values in fields where e.g. allready a value exist. Now I want to make sure, that via data upload the values of a z-field can be deleted. I tried it out, but was not successfull.
Has anybody a idea how I can delete the entries of z-fields via data upload? Or do I have to delete the values manually in the contact profile?
Thanks for your help,
Lukas
