Wrong Delivery date determined in Stock transport delivery NLCC from PO
Since we upgraded R/3 from 4.6C to ECC 6.0 we are facing problems in the Stock transport process.
We are using purchase order type NB for moving material from plant X from company 1 to plant Y from company 2. In the stock transport order we enter a delivery date which is the goods receipt date from the receiving plant. In tab "Delivery Schedule" we find the Material Staging date which is 25 days earlier because of the transportation time overseas.
When the materials are available in the supplying plant X we make a delivery. Before the upgrade the MBDAT (material availability date) was copied from the purchase order into the delivery date of the Delivery.
After the upgrade not the MBDAT is copied but the goods receipt date, which is 25 days in the future.
Does anybody know if we can influence this date determination in e.g. customizing.
Thanks in advance for your Help.
