Trace can be disabled for Framework Web applications
You can now ensure that end-users cannot run tracing when they execute their Framework web applications, even if they add TRACE=Y or TRACE=SYSTEM to their URL.
By setting the field #CHK_TRACE to FALSE in the web sign-on IIP, all tracing after sign-on will be stopped.
The shipped version of this is function UF_SYSBR/UFU0001. See the source code of UFU0001 for more details.
