title: AX 2012 initFrom methods
body: <p>I understand that these initFrom(TableName) methods are to initialize fields in a table for related tables.  Where are they called from?  I want to follow this pattern but where do I call this method? </p>
  
  <p>Every documentation on this pattern just tells me what I said above and no examples of using them.  I see examples of them being created.  </p>
