configuration of connections for bi mobile app

Dear all,

I want to predefine a connection for the bi mobile app with a sapbi link.

Therfore the managed app configuration should contain the parameter conn.list.1. My problem is that the value that contains the sapbi link can not be saved.

What is the problem here? Has it to do with the format of the link? In my opinion the value should be string value.

Best regards,

Daniel
