I'm trying to generate DDL for a model with Data Modeler 23.1 and it fails but it works fine with Data Modeler 19.2.
The issue is on views definition when a view is composed by union of two tables and a column in the second table is defined by a function.
See picture in attachement.
In this example column “a_date” is duplicated. In DataModeler 19.2 the behaviour is as expected and just one column is generated.
