hrmss_emp_overview_profile custom config not working

hello everybody, got a small problem and need some help to direct me in the right way:

1. wd-application: hrmss_emp_overview_profile --> copied the application config into zhrmss_emp_over_profile.

2. then I hid both the tab pages in it as I only need the short profile.

3. Then went into lpd_cust and changed mss navigation launchpad from OBN to wda aplication with above z-application config id.

4. now I try to call this via the NWBC... and I get the error --> FPM start event was cancelled.

I am at my wits end... can someone tell me what I have done wrong in the above and direct me towards the right way of doing it? Thanks you.

Count.
