batch determination in IM vs WM

Hi,

Is there a best practice of using batch determination in IM vs using that in WM. I am asking about batch determination in a production order/delivery where the WM TO just inherits the batch which is already determined and then stages it. Is there any downside to to having the WM just stage the batch and not do the actual determination and let IM handle it ? Or is it better to do it at the WM level ?

Thanks
