Type /DMO/CL_RAP_NODE is unknown

[newoutlaw98]

Hello all,

I was working on the Fiori Elements exercises as part of the openSAP course. I installed both the flight scenario and travel generator scenarios. However, when I attempt to activate the /DMO/CL_FE_TRAVEL_GENERATOR class, I get the error:

Type "/DMO/CL_RAP_NODE" is unknown.

Line 1565 and 1566 with reference to the code

name TYPE /dmo/cl_rap_node=>ts_assocation-name, " sxco_ddef_alias_name,
target TYPE /dmo/cl_rap_node=>ts_assocation-target,

Can anyone help assist?
