Exception occur:
org.hibernate.MappingException: Repeated column in mapping for entity:
DTSMethod236Type column: supplementaryquantityt_id (should be mapped with
insert="false" update="false")
at
org.hibernate.mapping.PersistentClass.checkColumnDuplication (PersistentClass.java:652)

I should write in persistence.xml something like this?:
<epackage
namespace-uri="urn:customs.ru:Information:CustomsDocuments:DTSout:3.0.1 ">
<eclass name="DTSMethod236Type">
<property name="....">
<column name="supplementaryquantityt_id" insertable="false"
updatable="false"/>
</property>
</eclass>
</epackage>

I don't understand how to get the name of the property
Maybe I have to do something else?

It is probably a nameclash of a join column which is used to persist an association. So you need to
search for an association from DTSMethod236Type to Supplementaryquantity (or vice versa), then
instead of the column annotation you need the joincolumn annotation to give the joincolumn another
name.

Thanks, it was helpful
Will it be everytime when class has to reference on the two same class?
May be in future Teneo will do this automaticly?

Teneo does this automatically but there is probably a limit to the length of the column name in your
case, if there is a maximum length on the sql column naming then Teneo truncates the part before the
underscore resulting in non-unique column names.
I have plans to completely change the naming logic so that others can more easily plugin their own
strategy.
