Adding Serialized items to Assemblies is a very important feature that we would like to see added to Sage50.  For proper traceability from the assembled item back to serialized components, is critical to many industries.  Industries such as Food, Pharma, Automotive Supply and Electronics all need this feature. Without this, we are forced to list a lot of confusing items on our sales invoices, because we cannot include assembled items that include serialized items.  It may be asking too much at this time.  However, being able to include assembled items that include serialized items into another assembly would be ideal!  Multi-level Serialized Assemblies, must be something that others need, yes?
