Automatic Warehouse System is new demo layout in 4.9 eCat. You can find it under Layouts type. Layout demonstrates Kovasat warehousing components in action that were added recently to eCat. Layout demonstrates ways you can simulate storage and retrieval of goods. It also shows how to create initial warehouse load using VariablesCache custom statement (https://forum.visualcomponents.com/t/variablescache-transportpatternin-help/).
Old Warehousing layout has been removed from eCat. While it was a nice layout it was made with pure python. Nowadays we try to simulate flows using process modeling and for that this new layout is much better example.
