Restrict New Hire Life event for part time employees.

Summary:

We have a requirement, where in we do not need the 'New Hire' life event to trigger for part timer. We tried using the below formula, attached it to data change under 'Per change causes life event'. However, it does not seem to be working.

Any suggestions to achieve the requirement would be helpful.

l_return = 'N'
IF (PER_ASG_FULL_PART_TIME = 'FULL_TIME') THEN

(l_return = 'Y')

return l_return
