Birthdate differs from pension insurance fund number

What causes this issue?

The employee's date of birth in infotype 0002 does not match the date
of the PI number.

System Response

The system issues a warning.

How to fix this error?

If the employee has a different PI number to the date of birth, contact
the health insurance fund. The health insurance fund informs the
pension insurance institution, which makes the decision about whether
to issue a new PI number.
However, if the date of the PI number matches the employee's date of
birth, and the warning still appears, the date of birth must have been
stored incorrectly in infotype 0002. Carry out a feature generation and
then re-enter the data in infotype 0002.
