Billing Date = planned GI date

Question

hei all,
i have requirement that need to set billing date (in billing doc) = planned GI Date or request delivery date.
case:
i made SO for req delivery date = end of month (31.1.2010), system propose Planned GI date (31.1.2010).
in fact, GI will be done in 5.2.2010, then billing date (in billing doc) will be same as actual GI date (5.2.2010)..
all i want is billing date = planned GI date (31.1.2010), because i want to capture exchange rate in that date (31.1.2010) not in 5.2.2010
kindly ur valuable input..
thanks
best regard,
Hendry

Answer 1

Dear,
1) Created date means on which date you create invoice but billing date means on which date you want to do bill.
   Planned GI date means on which date you want to plan GI. Suppose your planned GI date is 31.01.2010 but your actual GI date in 02.02.2010 then billing date should be 02.02.2010 or after this date.
2) If account not done of billing document then you can change the billing date.
   VF02 ---> Display Doc. Header Details --> In Header Tab --> Change Billing Date.
May be it will help to understand matter.
