Custom Z-Reports in F4940 My Reports

Hi Specialists,

we want to integrate custom defined Z-reports (ALV) into the App My reports (App-ID F4940). I followed the Cookbook (Cookbook: Transfer Reports from Manager´s Desktop (MDT) to the My Reporting Fiori App). Now I want to integrate a Z-Report, but it doesn´t work. A message appears (HCMFAB_MYREPORTING022) is not available.

Can anyone give me a hint?

Regards

Sigi
