The rule in plain words
PD should not exceed 100%
In Credit and counterparty credit risks and free deliveries: IRB approach to capital requirements: breakdown by obligor grades or pools (CR IRB 2) (OF08.02.01.01): every value in the cells it covers must not be more than 1, and every value in the cells it covers must be zero or more.
This is a warning. It does not stop the return on its own, but your supervisor may ask you to explain it. It runs only when your filing indicators mark OF08.02.01 as reported.
