trace log in BRF when WEB UI is used

Hi All,

I use WEB UI in CRM to change the status of provider contract and would like to trace all activities in BRF(not BRF Plus!!!) when some events in application class CRM_CFG_SC are raised.

I set in BRF transaction for mentioned application class:

1.Trace class = CL_TRACE_BRF

2.Impl tree class = CL_WB_TREE_DEFAULT_BRF

3.RunTime mode = 1 (or 3)

But as result I cannot see trace log to analyze BRF activities and fields.

I used transaction SLG1, FM BRF_TRACE_START_TOOLBOX and then BRF_TRACE_DISPLAY as was recommended but without any success.

What should I do exactly to see trace log after BRF events?

Regards,

Andrey
