Hi Markus,
sorry for the name confusion. I cannot confirm this for the sapnco.dll version 3.x, where the hexdump (= rfc data) is only shown in trace level 4 (as documented in the SAP documentation of the trace level here (under "Level"):
Zielsystem: Register Einstellungen RFC-Client - SAP Plant Connectivity - SAP Library
Configuring 2|ParameterData does not log the hexdump. And I think "ParameterData" is not a valid trace level, it is not documented and seems to have no effect.
Regards,
Bernd
