SAP Error Message - Details

• Message type: E = Error

• Message class: 5G - HR: Messages for Britain

• Message number: 171

• Message text: Prefix '&1' is not valid for the complete period between &2 and &3

What causes this issue?

The prefix of the National Insurance Number (NINO) you have entered in
this infotype has a restricted validity period.

System Response

The system has determined from the system table <ZK>HR-GB NI Prefixes
</>(T5G43) that the prefix of this NINO (the first two characters) is
only valid for a specific time period. Consequently, this NINO may not
be valid for the entire duration of the infotype record you are
creating.

How to fix this error?

You must check this National Insurance Number again. If this NINO is
time-limited, where the prefix is to be used for a limited period only,
ensure that this infotype record matches the validity period of the
NINO.
This validation is necessary to ensure that your entered NINO conforms
to the quality standards published by the Inland Revenue. An invalid
prefix for a NINO will cause the employee to be rejected during
End-of-Year (EOY) returns submission.

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.
