SAP Error Message - Details

• Message type: E = Error

• Message text: Schlüsseldublettenfehler; Satzübertrag. unmögl. (MigrObj. &4, Portion &1)

Was verursacht dieses Problem?

The system divides data into portions, which are then transferred to the
target system. The portion above cannot be transferred to the target
system because of a duplicate key error. This means that either one of
the records in the portion already exists in the target table, or at
least one record cannot be inserted, as inserting the record would
violate a unique secondary index for the target table.

Systemantwort

The system does not transfer any records from the portion to the target
system, and sets the status of the table to <ZK>Failed</>. The system
continues to transfer the remaining portions in the access plan.

Das System gibt eine Fehlermeldung aus und erlaubt Ihnen nicht, mit dieser Transaktion fortzufahren, bis der Fehler behoben ist.

Wie behebe ich diesen Fehler?

If you encounter this error when using SAP LT Replication Server,
proceed as follows:
Change the transfer behavior to 3 (Array Modify) so that all records
from the source system will be transferred to the target system. If a
record already exists in the target system, it will be updated with the
record from the source system. For more information, see SAP Knowledge
Base Article (KBA) 2331934.
If you encounter this error when using another application, fix the
issue in the target system (for example by removing the unique secondary
index) or change the transfer behavior as required:
Use transfer behavior 2 (Single Insert) if those records that can be
inserted will be transferred, and the other records that cannot be
inserted (for example, the records that violate a unique secondary
index) will be rejected.
Use transfer behavior 3 (Array Modify) to ensure that all records from
the source system will be transferred to the target system. If a record
already exists in the target system, it will be updated with the record
from source system.
If required, you can use transfer behavior 4 (Array Insert with List of
Duplicate Keys) to identify the keys of the records that cause the
duplicate key error.
