Other terms RFC, SAPGUI, RFCGUI_UNEXPECTED_DATA Reason and Prerequisites This note describes the tracing of RFC communication between the ABAPsystem and the SAP GUI. Solution The following steps should be carried out for the trace generation:  Activate acceptance of the exported trace ogw/export_trace_level = 1ordisp/accept_remote_trace_level = 1ogw/accept_remote_trace_level = 1 Delete RFC trace in the ABAP back-end system  oSM59 --> RFC --> Delete TraceoSM50 --> Process --> Trace --> ResetoSM50 --> Process --> Trace --> Dispatcher --> Reset FileoSMGW --> Goto--> Trace --> Gateway --> Reset File  Activate the RFC trace on the front-end side and export to the ABAP back end  oActivate the RFC trace in accordance with Note 696275oSet the following environment variables in the front-end program-DPTRACE = 3oTrace setting in the file SAPFRONT.ini for section-specific[Trace]:-Mode=0x30F-Components= Diag prior parsing,Diag to server,RFC (without aspace after the comma)  18.08.2013Page 2 of 4  SAP Note 1320424 -RFC tracing in RFC-GUI communication Increase the trace level for the DIA work process type in the ABAPsystem  oSM50 --> Process --> Trace --> Active ComponentsoIn transaction SM50, set the trace level for the DIA work processtype for the following components to 3 :-M (Task handler)-A (ABAP proc.)-Y (Scrn. proc.)-D (Diag Processor) Increase the gateway trace level in the ABAP system  oSMGW --> Goto --> Trace --> Gateway --> Increase Level Increase the dispatcher trace level in the R/3 System  oSM50 --> Process --> Trace --> Dispatcher --> Change Trace Level(set the value to 2) Reproduce the error scenarioReduce the trace level for the DIA work process type in the ABAPsystem  oSM50 --> Process --> Trace --> Active ComponentsoIn transaction SM50, set the trace level for the DIA WP type to Default values .
