Questions about Booking and Accrual

Hello

BOOKING:

so when we do booking; the booking transaction has LIAB and ROU for present term as wells as FUTURE Payment term line. Do the Numbers for future payment term go to GL?

ACCRUAL:

When we do accrual each month; the accrual is calculated for present payment term line for a month BUT it also calculates Amort and INT Exp for future payment terms. WHY?

Does the Future Payment term AMORT and INT EXP go to GL? WHY?

Thank you,

Rinesh
