Quelle est la cause de ce problème?

The attribute used for identification/assignment is not unique.
This is the result of one of the following:
The transfer contains another record with the same identifying attribute
(applies to non-<LS>KEY</> fields).
The transfer contains another record with a different identifying
attribute that leads to the same database record.
The transfer contains at least two records with this attribute.
&SYSTEM_RESPONSE& (EDT only)
This error is serious enough that the record was placed on the hard
drive and not in the batch input session.
This error takes priority over any other errors in this record.
&WHAT_TO_DO& (EDT only)
Generate the record anew and check the identifying attributes.
