Absolute Navigation
Use
You can activate absolute path navigation for the portal in Web Dynpro ABAP, by using the portal manager (interface IF_WD_PORTAL_INTEGRATION, method NAVIGATE_ABSOLUTE). You can generate a template using the wizard, in which you then enter values.
With the absolute navigation tool, you must know the name of the page to be displayed in order to pass it to the method.
The navigation target is the only parameter required here. It stands for an absolute address in the portal. The other parameters are used for controlling the navigation and are optional. You can set business parameters and parameters for the respective application launcher in the portal. To transport business parameters correctly to the target application, you have to set the parameter USE_SAP_LAUNCHER. If it is an SAP application (for example, BSP Web Dynpro, and so on), you have to set the switch to TRUE.
