How to track cmi.progress_measure in Storyline

Dear Community,

maybe you can help me out here.

I want to track the cmi.progress_measure (SCORM 2004 3rd) with an Articulate Storyline e-learns in dependancy of the viewed slides and/ or the reached score in the final quiz.

Is this possible?

I found some code in the SCORM2004Functions.js in lms folder that handles this SCORM field but I don't understand the logic behind this.

Line 1467 and following:

function SCORM2004_SetProgressMeasure(numMeasure){
 WriteToDebug("In SCORM2004_SetProgressMeasure");

Thanks for your support

Regards

Oliver

  var blnResult;
  SCORM2004_ClearErrorInfo();
  blnResult = SCORM2004_CallSetValue("cmi.progress_measure", numMeasure)

I also tried to log this value in the SCORM cloud and our LMS but it isn't tracked.
