OBN.04 How to Debug OBN

If you have an understanding of ABAP knowledge and like to debug, it is relatively simple to debug by using an OBN resolve sequence. All OBN calls for both NWBC for Desktop and NWBC for HTML are resolved on the server in method CL_NWBC_RUNTIME35->RESOLVE_NAVIGATION. Set an HTTP breakpoint for the correct user and client in this method. (Important: NWBC for Desktop caches resolved OBN calls, first flush the NWBC cache by using CRTL+ click on the Help menu.) The resolving steps involve first retrieving all possible OBN targets that are mapped into the assigned roles, selecting the correct OBN target, and finally doing the parameter mapping of incoming parameters onto the target application parameters.
