hi,
Ok so the thing is till the time you are passing the data to FM for dwonload the delivery no. is there.
But are all characters not seen in csv or only one or two digits are missing?
If you are using ALV grid display and then downloading the file then their may be one cause.
1: you will have to check the filedcatalog build where in you are building the fieldcat.
There are cases wherein if the length of variable is less then the actual length then in SAP you will see the delivery in alv but some characters will be lost in download because the variable length used in fieldcat is less than actual lenght of delivery.
Rgds,
