Tracing Functions Using APL in a Workflow

If you want to perform traces to see which functions change a UDR, you can use the trace() APL function.

The trace command syntax is as follows:

void trace (drudr myUDR, string Message)

Parameter	Description
`myUDR`	The UDR to trace on
`Message`	The message displayed in the trace
Returns	Nothing

Example trace() Function

This is an example of how the trace() function can be used in an Analysis agent.

import ultra.Default.traceudr;

consume {
  MyTraceUDR tu = {
      "intField": 1,
      "strField": "first"
  };
  trace(tu, "Sending to Dest1");
  udrRoute(tu, "dest1");
  
  tu = {
      "intField": 2,
      "strField": "second",
      "subUdr": tu
  };
  trace(tu, "Sending to Dest2");
  udrRoute(tu, "dest2");  

}

When doing a trace in Desktop, the messages defined by the trace() function will be shown in the table displaying trace results:
