Subcontracting: Picking Relevancy of service Line Item in Inbound Delivery

Hi experts

I have a challenge. There is a Subcontracting PO having 2 line items, 1st one is Trading product which is the physical finished product & 2nd line item is service line item( service material type). So Can we create a Inbound Delivery wrt PO having Service Line item to do receipt?

I tried creating Inbound but failed, error is : material ( service line item) is not extended to Warehouse. But my requirement is: it shouldnu2019t be extended to WM views so that it only appears in Inbound delivery as line item & it should not be relevant for Picking.

Any idea how can we do this?
