Error in delivery order created with reference to STO.
I am working on transportation. I have configured shipment documents for delivery orders created wrt to Sale orders and STOs. For sale order everything is working fine. I can change quantity in delivery order created wrt to sale order but when I am trying to change quantity in delivery order created wrt to STO system is giving me this error.
5 serial numbers are already maintained. Quantity cannot be changed
Message no. VL424
There is 5 quantity in STO but I need to change it in delivery order because sometime there is not enough space in truck and ware house persons change quantity as per actual loading quantity.
