serial number issue
I have changed the serial number of a material from 300 to 300*.THe system accepts that.
Now in serial number history, when i checked for 300 *,it shows the order number..
and for 300 it is showing"no history exists for 300".. upto this there is no problem..
But if i want to have the serial number for a material as 300,it is not allowing me.The system gives an error"serial number already exists".
How to solve this issue...
