The CouplingInterface.RecordInteractions data model control allows you to reproduce the interactions with System Coupling without actually connecting to System Coupling. This can be used to debug issues found inside participant solvers without using System Coupling, and it can also be used for integration testing of the SCP library inside the participant solver.

For more detailed information, see Testing and debugging tools in the User guide section of any 2024 R2 or later Participant Library documentation.
