Why is my Enrolment - Active student not synchronising into Sentral data layer?

The reason for this is that the student was not linked to a Primary Residential Household. This is set by going to:

• Go to Enrolments
  
• access the student's enrolment record
  
• select the Associated Household 
  
• ensure the Residential Household For This Student' is set to Yes
  
• scroll down to Save.
