How to change Desciption of an existing MaterialID via Excel/XML Upload

Hi Community,

I need your help.

I try to solve this issue:

I want to upload an Excel/xml file to byd and update the materialID.

i.e. Two colums one with the MaterialID and one with the Description. The materialID still exist, and the descition must be updated form xxx to yyy.

I tried the way like in the Tutorial of Jens, but it doesn´t work!

Does have anyone other Ideas?
