Problem in vendor Return process.

Hi Expert,

I have a report for vendor return process.Currently everything is ok. but now end user want to some changes like in grand total.

Grand total = total + Taxes(12%+2%+1%+Add duty+5%)

But in some cases end user want to print

grand total = total value

they have a condition when MRP indicator is Tick (in MIGO)  then print

grand total : total

When MRP indicator untick then

Grand total = total + Taxes(12%+2%+1%+Add duty+5%)[(curently this is using)]

I am using this logic for grand total in my program:

grand = item_tot + lv_cst + J_1IEXCHDR-EXBED + J_1IEXCHDR-EXADDTAX1 + J_1IEXCHDR-ECS + lv_adi.

So Please expert suggest me for the solution.

Thanks & Regards
