it's good idea but i need to deal with moving average i want to ask is sap recalculate after i entry the ap invoice retroactive ???
by the way if i will use your solution i don't need to do adjustment journal entry cause sap b1 in case you use standard cost for example item fixed price = 6 and you purchased it =7 in this case sap b1 will post the variance to variance account automatically .
thanks a lot
