Can we pass LER ID in ben_fn_get_char_value function to fetch the value of life event occurred date?

Summary:

I am trying to fetch the Life event occur date (promotion LE) in Rate Start Date formula of another LE (work anniversary LE). As per the oracle docs, I got reference to use ben_fn_get_char_value function, but it is giving the occur date of current life event (work anniversary LE). Is it feasible to input LER_ID in this function to get the occur date, for example-

l_leod_date_char = ben_fn_get_char_value('BEN_PER_IN_LER'

,'LF_EVT_OCRD_DT',' '

,' '

,'LER_ID'

,l_ler_id

)
