==Why have different versions of the same template?==__NOEDITSECTION__
What data is collected in a MAP changes over time and therefore the templates changes too. When opening a filled in Data Entry Form the template used as layout for showing the data collected also shows which questions where were asked then. Hazards created 2011 most likely do not have fields like Evidence but in 2014 they do.
There are situation where you would like to switch templates. E.g. you have found an embarrassing misspelling in one label or a term that your MAP is using has changed e.g. from ''Dog SOP'' to ''Animal SOP''.
