SCORM 2004 4th Edition and Success Factor LMS

this is because you added a content object, not choosing add content package to the item. you first do content import, then if your item is already created, you add content package (the scorm zip  file). you get this message if you chose object instead of package. an object could be a SF LMS assessment, or a pdf policy etc. To Chris point below, you have to create a content package ID at the time of import content, and you can rename the content object the same name too for easy searching. I've attached the admin guide. go to page 50
