Creating a New Model 
You have defined the needs of your application and know:
Which data services (such as queries, BAPIs or other RFCs) you need in your model
In which back-end system each required data service resides
The alias defined in the portal for each back-end system
The name and password of the user has been mapped to the connected back-end applications
Choose or click the
(New Model) toolbar button.
The Create a New Model dialog box is displayed.
In the Name field, enter a name for your model, adhering to these conventions:
Only alphanumeric characters and underscores
No spaces or punctuation marks
No special characters
Click OK.
Note
To create a model in a specific location - not the location indicated in the Path field - choose . In the Model Browser dialog box, select the folder
in which to create the new model (you can also create a new folder using the
(New Folder) toolbar button) and choose the
(New Model) toolbar button.
The model is created in your workspace on the Visual Composer server and the Compose Model task panel is displayed at the right, with a set of icons indicating the different model elements that you can create: Package, Page and different types of iViews.
