Different account posting for movement type 412 E ?How?

Question

Account determination for the stock transfer from own stock to sales order stock:
When we transfer the stock from own stock to sales order stock, the amount which gets transferred from own stock to sales order stock is equal to quantity multiplied by the MAP of the item.
We have a scenario where there is a material A having MAP = 10.Quantiy of own stock for A is 100 EA .Now we have got a sales order for A with a quantity of 20 EA for a particular customer .We need sales order stock for this order at a special purchase rate say 8.
Next we have modified the movement type 412 E in such a way that when we transfer the stock from own to sales order stocks it will ask for the amount of the total quantity transferred. When I transfer 20 EA with movement type 412 E it prompts for the amount where we have provided the value 160(=20 X 8). Then save the posting. Accounting entries which happens are as follows:
Dr Stock    A/C u2013 310000       -
160
Cr Stock    A/C - 310000        -
160
In the process it recalculates the MAP of own stock. New MAP = ((100 X 10) u2013 160)/80= 10.5
We do not want the MAP to be effected in this process. We want a posting as below:
                  Dr Stock    A/C u2013 310000       -
160 (for sales order)
                  Cr Stock    A/C - 310000        -
200  ( for own stock)
                  Dr Gain/Loss account -       -
40
In this process the MAP of the own stock remains as 10.But this type of posting does not happen as long as you have own stock available. Is there any way to do the above posting with movement type 412 E . Reversal entry should be possible with movement type 411 E.

Hi,
I am doing the reverse. Transfering Unrestricted stock to Sales Order stock. So it should appear in MBBS.
But in my case for example, if there is a sales order with 3 items, for 2 items posting is as follows:
Inventory account Dr. .....
Inventory account Cr. .....
But for 3rd item,
Cost of Goods Sold (COGS) Dr. .....
Inventory Cr. ....
So in MBBS, only first 2 items appear and not the third one.
Can u tell me what can be the reason for this.
