How To Fix 5Q456 - File &1: ZK01 notification with same Zusy-ID &2 already imported

SAP Error Message - Details

• Message type: E = Error

• Message class: 5Q - Error Texts for Public Sector

• Message number: 456

• Message text: File &1: ZK01 notification with same Zusy-ID &2 already imported

What causes this issue?

During the program run, a ZK01 notification was already imported with
the same identification number (Zusy ID) for the personnel number.
A ZK01 request should be uniquely identified by the Zusy-ID. In some
cases, however, it is posible that requests with the same Zusy-ID are
repeatedly sent or one Zusy-ID is used for different requests.

System Response

Since multiple notifications with the same Zusy ID cannot be processed
in a single program run of the program <DS:RE.RPCZFAD0_INBOUND>
Processing of All Notifications in Inbound Directory</>
(RPCZFAD0_INBOUND), only one notification is processed now and saved in
the system. The files with notifications that are not yet processed
remain in the inbound directory and can be imported in additional
program runs.

How to fix this error?

To process files remaining in the inbound directory, you restart the
program <LS>RPCZFAD0_INBOUND</>.

Procedure for System Administrators

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

• What is the cause and solution for SAP error message 5Q456 - File &1: ZK01 notification with same Zusy-ID &2 already imported ?

  The SAP error message 5Q456 indicates that there is an issue with the import of a notification (in this case, a ZK01 notification) because a notification with the same Zusy-ID (which typically refers to a unique identifier for the notification) has already been imported into the system. This can occur in scenarios where data is being imported from external systems or during data migration processes.
  Cause:
  
  Duplicate Notification: The primary cause of this error is that the system has detected a duplicate notification with the same Zusy-ID. This can happen if the same notification is being imported multiple times or if there is a data integrity issue in the source system.
  Data Migration Issues: If you are migrating data from one system to another, it is possible that the same notification was included in the migration file more than once.
  Incorrect Data Preparation: The data file being imported may not have been properly cleaned or deduplicated before the import process.
  
  Solution:
  
  Check for Duplicates: Review the data file you are trying to import to ensure that there are no duplicate entries for the same Zusy-ID. Remove any duplicates before attempting the import again.
  Verify Existing Notifications: Check the SAP system to see if the notification with the specified Zusy-ID already exists. If it does, you may need to decide whether to update the existing notification or skip the import for that particular entry.
  Adjust Import Logic: If you are using a custom program or script to perform the import, ensure that it includes logic to handle duplicates appropriately, such as skipping existing records or updating them as necessary.
  Consult Documentation: Refer to SAP documentation or support resources for specific guidance on handling this error in the context of your particular SAP module or version.
  
  Related Information:
