[ratana_pouy]

Dear All,

There is one purchase order with account assignment for a internal order.

i am wondering how transaction key KBS trigger in MIRO. here is transaction

Goods Receipt:

GR QTY= 25,416.65

GR Value=  45,922,805

Unit Price= 1,882.72

Exchange Rate:1,806.80

Invoice Receipt:

IR QTY= 15,250.00

IR Value= 28,212,500

Exchange Rate:1,850.00

i did manual calculation, FX Gain/Loss should be

IR QTY * GR FX Rate = 15,250.00 * 1,806.80=28,711,482

28,711,482 - 28,212,500 <IR Value> =  498,981 

systen created additional entry for KBS with amount: 434,167 from FX gain/loss

System created entries:

Cr. AP........................................ 27,507,187 (KBS)
