  The SAP error message CNV_IUUC_REPLICATION420 indicates that a certain functionality related to data replication is only supported in SAP S/4HANA systems.

  Consult SAP Notes: Look for relevant SAP Notes or Knowledge Base Articles (KBAs) that might provide additional context or workarounds for the specific functionality you are trying to implement.
