You can now use the Order Management HTML user interface to create, update, and manage orders. The HTML user interface is in addition to and co-exists with the existing sales order windows and Order Information Portal (OIP).
The HTML user interface is an additional option, if you desire a modern, easily configurable, tablet friendly user interface. This interface offers functional parity with Sales Orders, Order Organizer, and Scheduling Organizer. It shares a common foundation with the existing sales order windows, Process Order API, and Order Import.
You can access this interface using the Order Management, HTML User Interface responsibility. Access to this is controlled by roles. You can have various combinations of authorization granted either through a permission set or through grants. Additionally, the HTML interface is integrated with FND Security to enable rule-based access to the summary and detail views of sales orders.
