Packing material appearing in delivery when TO confirmed

[hark101]

Hi everybody. Recently this problem has been happening on deliveries from plant transfer POs. When the TO is confirmed for the delivery, the packing material from the UC is placed as a line item in the delivery. This is not supposed to happen, packing materials are not supposed to be copied into the deliveries in our processes. Can anyone help?

Knowing how they can be created should enable you to reverse the setting, check the change history of the customizing, if it worked before as desired  then somebody must have changed it.
