If a customer order shorts due to a haulier caused error i.e. late stock transfer within the network. What is the most efficient way of locating the PO at fault? ATP will auto code it to haulier but doesn't offer any further detail as far as I can see. Instead I will have to use MB5B to find possible inbounds the customer order would have been reliant on, but this is time consuming, and if a stock transfer fails it won't show at all.
