PA52 Doesn't Do Date Validation?

Hi All,

We have a Personnel Action (PA52) that populates the PEM-BEN-DATE-x fields.  While doing some data auditing, we've found that this PA is allowing invalid dates to be updated into PAEMPLOYEE.  The dates are in the proper format, but with an incorrect year, like "02/01/1070".  Trying to enter a similar date via HR11 throws an error because the date is prior to 1700.

Shouldn't invalid dates cause the PA100 to throw an error?

Thoughts?  Thanks.
