Hey guys,
I have a excel file and its content are two columns: first column ist the item no. and the second one is a new description.
So my goal is to update the already existing items in my database with the new description.
When I create the xmlport, do I have to insert also the item no. as a new element? Or do I only need the description field as a new element?
Then in the code I would check, if the item already exists, if yes, then I would update it.
I found that code snippet, which I would like to use for that case:

Is that the right way?
Does the xmlport need some special properties? Like Autoupdate = Yes?
