Hi Anand
The courselab cmi handles messaging between the module and moodle. When published as a SCORM 2004 your module has a wide range of information it can potentially pass, BUT it needs to be asked which is what your LMS does.
The first place you should look for the answer to this is the Moodle forum to see if this is a problem with moodle or courselab, and how moodle should be configured so that it asks for the information to start with.
