Issue in switching on performance tuning using /ron & /roff

Hi Experts,

When I am in a break point of a program, if I switch on performance trace using the ok code "/ron", it throws the error "Particular units is not switched on". I know that option is available in SE30 variant. But how to swich on that, if we start trace from programs debug screen. Kindly help me out. I would like to trace for a particular subroutine. How to do that.

Thanks and regards,



no, it works a designe.

with the new debugger we have 2 workprocesses.

1st your apllication (running with particular units)

2nd the debugger (without particular units)

in SE30 you can filter for modularization units...

will that help?

Kind regards,
