Formula to compare inventory that is NOT in another inventory list
On top of a previous request to compare inventory lists. I'm trying to dig a bit deeper.
My Existing inventory list has all of our product serial #s, our central inventory list has all of our purchased serial #s and over time our vendors will backtrack and put old serial #s in our central inventory list.
But what I'm trying to accomplish is search our Central inventory list and see what is NOT in our existing inventory list.
they are separate tables, Table A Existing Inventory has all all of our product serial #s, Table B has our central inventory.
any insight would be helpful.
