Hi Manish,
When you show Sales Order Entries, have a column to show a menu control for each row to show the navigations available for a sales order entry. Menu items are going to be dynamic. Dynamically create a menu item for each navigation you have for sales order entity. Inside the menu item, use the custom data to store the relative URI to corresponding target entity. This relative URI is available in the sales order data itself (oData returns it).
Moment a menu item is clicked, create a new table and bind the data using the relative URI.
Thanks
Krishna
