DRAFT: A draft activity is an activity that is not yet available to learners, or you have not entered enough information in JA-PARS for the activity to be considered active. JA-PARS assigns the draft status. You do not have to set it.
ACTIVE: As long as the end date of the activity has not passed and you have entered all fields, JA-PARS automatically moves the activity to active status. You do not need to set the status as active.
READY TO CLOSE: Once the end date of an activity has passed and you have entered all fields, JA-PARS automatically changes the status to ready to close. You do not need to actively set an activity as ready to close. At this point, you can enter your final total learner counts, provide any final details about commercial support (if applicable), and close your activity.
CLOSED: Once you have completed and updated your total learner counts, you will need to change the status of your activities to closed. JA-PARS does not do this since it cannot determine when your learner counts and other details are final. You will be able to set the status as closed for an individual activity, or you can select all the applicable activities and set them as closed at the same time, or you can use any of the batch or web services methods.
See this guide for details about the fields required for each status.
