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

System Response
The system has determined from the system table HR-GB NI Prefixes(T5G43) that the prefix of this NINO (the first two characters) isonly valid for a specific time period. Consequently, this NINO may notbe valid for the entire duration of the infotype record you arecreating.

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