My new model opens as a Data Warehouse model and the display is Dimensional model. It should be Logical/Physical model, and not Logical/Dimensional model? Why does it open like that and how to change it back to Logical/Physical model?
A new model opens based on the settings from the previous model worked on. So, if the last model worked on was for a specific database and was a Data Warehouse model, the new model will have the same database and notation by default. This can be changed by switching to Data Warehouse (or Dimensional) settings. To change it, go to Model | Model Properties and, in General Tab, under Modeling Features, uncheck the boxes for 'Is Dimensional' and 'Data Movement'. That will convert it to Physical. You can also change the Notation for both Logical and Physical sides in the same menu.
