This file stores the transaction information associated with each serialized inventory item. There may be multiple records in this file that relate to a single Serial Master record. As each serialized inventory item is received, transferred, and or invoiced by the system, a record of the transaction is automatically created in the Serial History file. Records are also created in this file whenever the operator manually creates a Serial Master record or when the operator edits the serial number, item number, owner, vendor, location, or sold to associated with an existing serialized inventory item. These Serial History transaction records provide the operator with a complete transaction history for each serialized item in the system.
