Hi Sid,
Sorry for the late response.
In my custom configuration, I have made the tab page as default with Weekly page as the default page. But the application does not show that. I have followed this note https://launchpad.support.sap.com/#notes/1796328
and made changes to the OVERRIDE_EVENT_OVP method to call my custom config.
If I also make changes to the iview with the custom config, I get the error message. Please let me know what should I do.
Regards,
Sai
