PO output determination based on item type (material or service)

Dear Experts,

Please give me a hint whether it is possible to configure a PO output based on the line items of the actual PO. (I would like to issue an output automatically if there is at least one line item on the PO, which is a material [not a service].)

Is this configurable by the condition technique?

If not by configuration, how could this be achieved by coding?

Thank you in advance!
