The best you can do is use the Date Last Maintained (DATELASTMN) field.

If you use the ICUNIT table, you should be able to get a decent date to work with;

SELECT        MIN(dbo.ICUNIT.AUDTDATE) AS CREATED, dbo.ICITEM.ITEMNO AS ITEM
FROM            dbo.ICITEM INNER JOIN
                         dbo.ICUNIT ON dbo.ICITEM.ITEMNO = dbo.ICUNIT.ITEMNO
GROUP BY dbo.ICITEM.ITEMNO

Brilliant! ICUNIT is rarely ever touched after the item is created!!! THANK YOU!

You're welcome!  :-)

Hmm, for whatever reason, this returns way more than it should.  We may have done an inventory dump and load a few months back which, I assume, would have touched the dbo.ICUNIT.AUDTDATE.  Oh well.

That's correct.  The AUDT fields are used primarily for database concurrency but sometimes we can get away with using them for other purposes - until a dump/load happens.

Would getting the date of the first receipt be of any use or does your query need to know when the master record was created?

Date of first receipt would be great also. Where might I find that?

ICHIST or ICIVAL.  There's also potentially ICILOC.DATEACTIVE.

Looks like this gets me a good result for first received date for each item:

SELECT MIN(TRANSDATE) AS FIRTRECDATE, ITEMNO AS ITEM
FROM dbo.ICHIST
GROUP BY ITEMNO
