OData Services for Situation Handling?

Hello,

I'm currently following the guideline of setting up Situation Handling.

To configure your situations, you need some apps for which you need to set up OData services in transaction /IWFND/MAINT_SERVICE:

The activation of the object-based services worked perfectly fine.

However, I can't find the message-based services in the system, in particular CA_SIT2_MST_SRV (/IWFND/MAINT_SERVICE) and c_sitn2mysituation_v4 (/IWFND/V4_ADMIN).

Are these services included in a different version than the object-based ones?

What do I need to do to get the message-based services?

Thanks and best regards,

Elias
