    Open Live Script

    This example shows how to create a view and apply it to the Requirements Editor and Requirements Perspective.

    Open the myAddRequirements requirement set, which contains requirements with Type set to Functional.

    rs = slreq.open("myAddRequirements");

    Create a view with the name NewView.

    myView = slreq.View.create("NewView")
    myView = 
  View with properties:

          Name: 'NewView'
     ReqFilter: ''
    LinkFilter: ''
          Host: ''

    Set the requirement filter to only display requirements that have Type set to Container.

    myView.ReqFilter = "{'ReqType','Container'};"
    myView = 
  View with properties:

          Name: 'NewView'
     ReqFilter: '{'ReqType','Container'};'
    LinkFilter: ''
          Host: ''

    Check if the view is valid.

    tf = isValid(myView)
    tf = logical
   1

    Apply the view to the Requirements Editor and Requirements Perspective.

    activate(myView)

    Confirm that the active view is NewView.

    appliedView = slreq.View.getActiveView
    appliedView = 
  View with properties:

          Name: 'NewView'
     ReqFilter: '{'ReqType','Container'};'
    LinkFilter: ''
          Host: ''

    The myAddRequirements requirement set does not contain any requirements with Type set to Container, so all of the requirements are filtered out.
