Ok, now I can see. A quick search on your error message suggests that it has something to do with reading right to the transport file. Could that be the case? Have a look at Import transport error returncode 12 .
You could connect with a user that has 'SAP All' authorisation. To recreate the Qlik user directly in your system you could also contact Qlik Support for a specification of the objects included in the Qlik Role. But it is probably a lot easier to solve your import issues and import the role transport into your systems.
