Hi,
Components actual cost is only updated when they are consumed to service order
so you have to post Goods movement using 261 movement against the Order in MB11
As you know the actual cost of material once posted with Goods movement will be transferred to the Service order from the Material master - Accounting tab
Once you do Goods movement you can see the status on the service order as GMPS
Try posting goods movement and check the actual cost
