Debugging Class ZCL_Z_***_DPC_EXT Method ***GET_ENTITYSET

Hello,

I click 'go to ABAP Workbench' in segw and I want to debug the method 'get_entityset', it is inherited from

ZCL_Z_***_DPC. I set breakpoints, but when I call QUERY Operation URL in Browser,it does not stop and I don't see the debugger.

Do you have any idea, how can I set breakpoints that the abap method 'get_entityset' will be stopped so than I can see the debugger?

Regards

Vladislav
