Our service department uses work orders in their repair process. As part of this process, they use serialized items on a work order that then goes into a build to produce a returned product to a customer. The expected behavior is that when a serialized part is added to the work order and the work order is firmed and released that when the techs enter the build process that the serialized parts move forward to the build process. This worked as expected in Sandbox in some light testing however now that we have moved it to production, there are work orders that do not carry the serial number forward to the build. We have to go back to the work order, remove the serial number from the work order for it to be able to be choosen on the build screen. I'm trying to gather data like if it is only happeing with certian parts (thinking there maybe something in the parts setup). I've taken a work order that had this problem and re-created it in Sandbox where it didn't have the issue. Anyone have thoughts on where else I can look?

@Mark Nelson bit of a shot in the dark, but often a lot of Serialized item problems come from people back-dating transactions, or editing past transactions. The SN would have been selectable initially, but as you push forward the item is suddenly not there anymore. Might be a trail to investigate

Thanks Olivier! I'm trying to trace this now as the service department brought one to us this morning and I've been able to duplicate the issue in sandbox from Item receipt forward. If I'm understanding what you have outlined, this wouldn't be the case for this one I'm able to duplicate as the IR to Work Order to Build was done with in a 5 minuite window. I'm testing a few variations of entering the items with the serial/lot number on a work order to see if there is a process issue before opening a netsuite support ticket. Any other thoughts are welcome! I was actually doubing myself that a serial/lot numbered item can be used in a work order for a build for a bit.
