3433995 - Error "Integrity constraint violation;301 unique constraint violated" in Data Flow for currency and unit codes


When executing a Data Flow in SAP Datasphere which involves currency and unit codes, following error may occur:
Integrity constraint violation;301 unique constraint violated

However Data flow uses same key as defined in source CDS View.


SAP Datasphere


Data Flows use the "Enhanced Format Conversion" to convert currency and unit codes from ABAP to ISO. However there are codes without unique ISO code.
Different from Data Intelligence Cloud, currently there is no way to change format conversions in SAP Datasphere.


Instead of using Data Flows, SAP recommends using Replication Flows.
