if you want to distribute reports to assigned persons, you have to do the following. First make a list box in the QlikView Document, where you created the report for distributing.
In this listbox you have to write all Email adresses, where the Reports should send.
After that, go to the Publisher.
Here click "Open Document" and in the "Field containing recipient information" you have to choose the item, where you have written in the Email-Adresses in your QlikView document. For me its not User like on the screen - it's the field "Email" - you see it in the first picture. So here I had to choose Email, not User.
If you entered a valid Email Adress select "Email Adresses" in "Check user identity on".
In Destination choose Email.
Now run the task and the Reports you choose in Publisher should be distributed to the assigned Emails.
I can suggest the Tutorial from Rob. You can find it here: http://robwunderlich.com/QvTutorial.html There are explanations about how to create reduction and loop and reduce distribution. Combine this with my post here, and you will get results
