New hire life event is NOT getting triggered when a pending worker is converted to employee

New hire life event is NOT getting triggered when a pending worker is converted to employee. The new hire life event data change has a simple FF which checks the action code.

Appreciate any kind of inputs. Thanks in advance.

FF code :

INPUTS are NEW_VAL(text), OLD_VAL(text), COLUMN(text), PK_ID(text),
BEN_ASG_IN_ACTION_CODE(text), BEN_ASG_IO_ACTION_CODE(text)

DEFAULT FOR PER_ASG_SYSTEM_PERSON_TYPE IS 'NA'
default for NEW_VAL is '****'
default for BEN_ASG_IN_ACTION_CODE is 'XX'

l_create_ptnl = 'N'
lterm = 'XX'
lterm = BEN_ASG_IN_ACTION_CODE
