  "metername":"RUNHOURS",
  "newreading":11}
  
  Click on Properties, In JSON Properties Mapping section create a
  new record for each map below:
  Target Attribute: ASSETNUM
  Source Property: $.assetnum
  
  Target Attribute: METERNAME
  Source Property: $.metername
  
  Target Attribute: NEWREADING
  Source Property: $.newreading
  
  Target Attribute: SITEID
