I need a serial number generated from a couple of sources. One is a "Unit

that the serial number was created. how can I do this? Thanks.

Perhaps:

=UnitNumber &TEXT(Date,"yy")&TEXT(Date-DATE(YEAR(Date),1,0),"000")

although if UnitNumber can have leading zeros, you might want to make it TEXT
also:

=TEXT(UnitNumber,"000") &TEXT(Date,"yy")&TEXT(Date-DATE(YEAR(Date),1,0),"000")

Date = date in the date column

DATE = the worksheet function DATE.

Sorry for the confusion.
