3643699 - Table columns automatically prefixed by replication flows in SAP Datasphere

Symptom

When creating local tables via replication flows in SAP Datasphere, table columns with technical names starting with an underscore (_) or having the same name as columns used for CDC are automatically prefixed with AUTOPREFIX_.

Environment

SAP Datasphere

Cause

Resolution

  1. Rename the target column in the replication mapping to a name that does not conflict with CDC columns.
  2. Alternatively, keep the Auto-Projection
