There is not a way to do this if you are sending via email. In that case, the recipient must be a user in NPrinting.
If you just want to create the reports by clinician and then save to disk, you can accomplish this with a cycle using the Clinician Name (or related) field: Cycling your reports ‒ Qlik NPrinting
First, create a field/object in the Qlikview application that lists all of the clinicians. Then, create each recipient in nPrinting (or, you can import from an Exchange address book). Then add the corresponding Filter to each Recipient entry. When this is done, assign each recipient to the Task that generates the report. When executed, it should send an email to each Recipient showing only their information.
Sorry, I didn't understand your issue in the other thread.
