Reverse Termination life event is not triggering

Please check the below FF & screenshots of the setup of Reverse termination, it is not triggering. Kindly let me know if I have missed anything.

FF:

inputs are BEN_ASG_IN_ACTION_CODE (TEXT)
l_create_ptnl = 'N'
If BEN_ASG_IN_ACTION_CODE ='ORA_EMPL_REV_TERMINATION'
THEN (l_create_ptnl = 'Y')

l_log_data = ess_log_write('l_create_ptnl =' || (l_create_ptnl))

return l_create_ptnl

Thanks in advance
