MRP Element in MD04

Hi All,

When in MD04, the MRP element corresponding to delivery is displayed as a line with the quantity, but no delivery number is displayed. Also, when we double click on the line, we can not access the delivery (not even for display by clicking on the glasses icon) and get the error message " Selected function cannot be used for the element" with error code Message no. 61111.

If we try the same with a Shipping notification element, it works perfectly fine, and we can go to the Purchase Order directly from MD04.

How can we set MD04 so that we can see the delivery number (At least), or ideally be able to access it by double clicking from the line?

Thanks
