After we transfer serialized items from one location to another, the serial number is "not available" for material issue (WO-I) or for sale (SO-E).  
 
The only work-around I have found is to delete the record of the serial number from the original location in TAS-D.
 
One more bit of info: one of the locations to which the items are being transferred is classified type "S", but the other is an inventory location.
 
Is the location of the WO or SO considered (properly) during the retrieval of the serial number? Or is the logic looking only for the first table entry for that serial number regardless of the location?
 

Transferring gives us a pop-up list and that is working fine. I can transfer into and out of any number of locations. However, once I have transferred serialized items out of our primary/default location I am not able to consume them. The number appears in the look-up list (F2) and can be chosen, but when the program tries to make the transaction we get a pop-up telling us that the serial number is not available (as if it is reading zero for that location).
