What causes this issue?

The system has tried to access an ABAP OO class in order to retrieve
information about deployed services. However, the required class &v1&
does not exist.
This situation can occur with the following object types:
Procedure Call expression
Call Procedure action
Formula expression containing custom formula functions
These object types have in common that users can associate them
dynamically with objects that exist outside the scope of BRFplus. For
the object types in question, this means:
Procedure call (both expression and action): The class to which the
associated static method belongs was not found.
Formula: The class providing the method used as a custom formula
function was not found.

System Response

The object cannot be activated.

How to fix this error?

Depending on the type of scenario you are working on, choose one of the
following alternatives:
If you are modeling a Decision Service Management scenario that is
deployed to a managed system, ensure that class &v1& is available in the
managed system.
If you are modeling a local BRFplus scenario, ensure that class &v1& is
available in the local system.
