Our business would like to print packing slips before delivery confirmation. In most cases, I can see the lot numbers from screen WK4STD1 but I cannot find the table where that lot is stored. SDELIVERYD seems to only have a lot number for some records. STOALL no longer contains the lot information once the delivery is created. The lot is not added to STOJOU until after the delivery is confirmed. 

Where are the lot values stored when a delivery record has been created but the delivery has not been confirmed yet?
