If the trace level is set with fatal, error, or warning, the R script output cannot be traced<br />
automatically.<br />
If the trace level is set with info, the R script output can be traced automatically.<br />
If the trace level is set with debug, the R script output as well as part of the input and output variable<br />
data will be dumped automatically.<br />
You can set to this trace level to check roughly whether the data transfered from <strong>SAP</strong> <strong>HANA</strong> to Rserve<br />
has the right structure and content, and whether or not the result variable structure is correct.<br />
