Hi,
If you want to know the clear picture of /4MI calculation. Do the debug in the function INTAX. You will get to know how the calculation is going on.
/4MI and /434 will calculate based on these condition.
* Compute monthly GTI only based on actual basis
IF projection_method = 1.
cur_act_prj_basis = cur_act_prj_basis * cur_prj_factor.
cur_nom_prj_basis = cur_nom_prj_basis * cur_prj_factor.
cur_434 = cur_434 + cur_act_prj_basis - cur_nom_prj_basis.
ENDIF.
cur_prj_factor = cur_prj_factor + 1.
* Compute remaining part of /434
cur_434 = cur_434 - amt_till_date - cf_year.
* Compute projected part of remaining /434
prj_amt = cur_434 - ( cf_reg + cf_irr + pre_emp_income
+ cur_irr_month ).
prj_amt = prj_amt / cur_prj_factor.
* Use remaining amount to compute the current gti
cur_gti(/4MI) = prj_amt + cur_irr_month + cf_reg + cf_irr - amt_arr.
