call ITSM Reporting from WD application

Hi,

I need to call the ITSM Reporting (CRM link id SM-ITSM-RP) out of a webdynpro application.

When calling the link out of the CRM WebUI the system generates a dynamic link like:

http://host:port/sap/bc/bsp/sap/crm_ui_frame/genericpostexecutionnewwindow.htm?GUID=5254C0A8963F1ED48ABDC1327AB3C6B5&COMPONENT_ID=C1_W1_V2&LAYOUT_SRV_CLASS=CL_CRM_UI_LTX_PAGE_LAYOUT_SRV

How can I call the application out of my webdynpro component?

I tried a bit with IF_CRM_UI_NAVIGATION_SERVICE but I did not get it up and running

Regards,

Richard
