How To Fix 5Q457 - ZK01 notification with same Zusy-ID &2 already exists

5Q457 - Overview

• Message type: E = Error

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

• Message number: 457

• Message text: ZK01 notification with same Zusy-ID &2 already exists

What causes this issue?

A ZK01 notification with the same identification number (Zusy ID)
already exists in the system 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

If multiple ZK01 notifications with the same Zusy ID are assigned to one
person, the report program <DS:RE.RPCZFAD0_KZ01>Creation of ZfA
Notifications KZ01</> (RPCZFAD0_KZ01) responds to the notifications in
the order in which they were created.
Since multiple notifications with the same Zusy ID cannot be answered in
a single program run of the program <LS>RPCZFAD0_KZ01</>, several
program runs are required in which the outstanding notifications are
answered one after the other.

How to fix this error?

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