When I run picking list (VL70), I get the list of the delivery order number. When I select one DO# and click on "print preview" icon on top, I get the normal print preview but when I do the print preview again, I get a new picking number on the print preview. When I continue on doing that print preview, I keep on getting a new picking number.
I checked my delivery order number document flow (VL02n) and found out that the picking number is not yet assigned on that DO#. The only time a picking number will be assigned to the DO# is when I click the process button (button before the print preview).
Question:
1. Is it normal to get a new picking number everytime you click on that print preview button?
2. How can I stop SAP from assigning new picking number everytime you do the print preview?
Please help. Thank you.
