Exception while navigating between components

78 Views

Hi Experts,

we have created a Z-component where we can retrieve and display opportunities related to the login user with some relationship. We can navigate from this component to the oppportunity by clicking on the opportunity name, as a navigational link is defined from the Z component to 'Target CUBT111M_OPPT.MainWindow Inbound Plug OVERVIEW ' . the navigation to opportunity screen is working fine from the result list of the search screen we had provided.

Now when we try to navigate from this opportunity overview screen through any of the hyper links(account name,employee responsible etc) we get an exception.For eg:- In case of navigation to the prospect of the oppty we get :

An exception has occurred

Exception Class CX_BSP_WD_INCORRECT_IMPLEMENT - Define NavigationalLink NAVIGATE_DISPLAY for source view CUBT111M_OPPT.MainWindow.

Program: SAPMHTTP

Include:

Source Text Row: 0

We have not defined any navigation link with name NAVIGATE_DISPLAY in runtime repository for our Z component .

There are navigation links defined with CUBT111M_OPPT as the target.

Are we missing any step here? Should the links be working as desired once navigation has happened to the standard component view?

What should be done in this case.

Any pointers in this regard would be highly appreciated.

Thanks in advance.

Regards
