Unfortunately they removed this feature in Captivate 6 per design in order to adhere to SCORM specs.
I highligted this problem as well earlier, but apparently the SCORM 2004 spec states that both cmi.score.raw and cmi.score.scaled should be supported by an SCORM 2004 compatible LMS. In Captivate 6 then using SCORM 2004 Captivate will send both cmi.score.raw and cmi.score.scaled and it's then up to the LMS to choose which one to use.
Unfortunately SCORM specs are read, interpretated and implemented in many different ways by different LMS vendors so it's not certain that your particular LMS support this.
The LMS that we use in my company does not support it so we can't use SCORM reporting from Captivate 6 at all.
