If the OData back-end service is located on a remote back end, users need permission to perform the RFC call on the back-end system.
You have created a user on the front-end system.
In the User Maintenance
transaction (SU01
) under , check if the user has the required authorizations S_RFC
and S_RFCACL
for trusted RFC.
If the user does not have the authorizations, assign a role including the RFC authorization objects S_RFC
and S_RFCACL
to the back-end user that corresponds to the front-end user.
