Open help for executables
The help URL can be transferred from the SAP® systems for executables of the SAP executable and Program types during project transfer and synchronization. This enables users to open the SAP® documentation containing detailed information on the individual executables. This function replaces the R/3 help call that is no longer supported. If you use SAP® Enable Now and have configured the system accordingly, you can 
open the process model related to the SAP Fiori® App for help.
Prerequisite
