I found it. The problem is in the SQL query used to generate the report within Report Designer since it doesn't take the qualifier into account there and needs to be manually added.
How to solve this problem ?
Do you have any way to do the job ?
I try to find the best way to manage the duplicated device.
In fact, I need to build a report where the duplicated devices appeared only.
The problem is how to add multiple MAC address from multiple networks cards ?
Is there a documentation in détails about the way to build a report with request ?
