When Expressor Studio runs a dataflow, logging information is displayed in the Results tab of the Status panel. Currently the detail of the logging messages is not managed from within Expressor Studio but by setting an environment variable in the Environment Variables window accessed from the Start > Control Panel > System > Advanced > Environment Variables button.
Create a System variable named EXP_TRACE_LEVEL and set it to a value between 1 and 7, which has the effects summarized in the following table. Specifying a value for this variable is completely optional and should only be done if you need to alter the detail of the logging messages, for example when tracking down a connectivity issue. If you do not explicitly set this variable, the default setting is 4.
You must restart Expressor Studio after setting or changing the value of this environment variable.
