Inventory Transfer or Transfer Order with Charges

Hi,

AX 2012 R2  - Saudi Arabia

I am in middle of the implementation and we got the following requirement, which believe is need to be customized. 

Suppose there are two sites, Site A and Site B, when we transfer from Site A to Site B we need to take care of the Charges as well.

• Site A Inventory Cost Per Unit $10
• Transfer cost Per Unit $2
• Site B Inventory Cost should have been $12

I dont think so it is already availble with default MS Dynamics AX 2012 R2 ( Saudi Arabia ) Functionality.

Let me know if any one already encountered the requirment in a better way,

thanks in advance.
