 Projecting share variables from history into the simulation time using a saturating projection is a common way to create the business as usual data for these variables.  ​ Projecting share variables from history into the simulation time using a saturating projection is a common way to create the business as usual data for these variables.  ​
  
-===== Example call to the sub-routine ​=====+To find the sub-routine ​related files look in: 
 +\\maxwell\whatif\whatifdocs\toolSubroutines\satProj
  
-There is a subroutine which can be hooked into your model and then called from views which does saturated projections with several parameters. 
- 
-Here's some reference code you would put in your view to call the sub routine and below that is the code for the sub routine itself
