AMDP Debugger not availabel

Hello,

when I will set an Breakpoint in SAP HANA Studio a window opens with the Message "AMDP-Debugger for the System is not available".

Our System is an SAP BW System 7.4 SP10 our HANA Database has the version 1.00.09400. SAP HANA Studo Version 2.1.6 with ABAP Development Tools 2.48. What I have to do that the Debugger is running?

Thank for your support.

Niels
