Shipment cost - Delivery tab and delivery item tab missing at the item level
We have an issue with the shipment cost .ie; at the item level of the shipment cost, we can see three tabs, ie; delivery , delivery item & shipment cost item. In our case only one tab can be seen ie; shipment cost item tab & the other two tabs are missing. please note, my delivery document is linked to the shipment correctly. Can you advise on the following please?
a) How delivery ,delivery item & shipment cost tabs are pulled in the shipment cost line ? where the settings would be maintained for the same?
b) What could be the reason for these tabs (delivery & delivery item tab) missing in the shipment cost line item level?
