Invoice exchange rate date.

Hi,

   I use R42800 to generate invoice, despite the different invoice date in one order, the exchange rate of invoices are always base on the order date not invoice date.

   For example:

   SO-1000 line 1 actual ship date(F4211.ADDJ) is 2014/1/1,line  2 actual ship date(F4211.ADDJ) is 2014/2/28. The order date is 2014/1/1.

   Run R42800 to generate two invoice for two lines and the invoice date,G/L date are set to 2-ship date in process option.

   The invoice date of line 1 is 2014/1/1, the invoice date of  line2 is 2014/2/28, but the exchange rate are the same.

   In exchange rate F0015, the rate for Jan. & Feb. is different.
