When entering a new item, or editing an existing Item, the following fields:
  Revision level
  UPC
Are skipped.
 
Pressing Enter after entering the 'Drawing' field results in the cursor jumping down to the 'Warehouse Control?' field.
 
Also, the title of the window truncates the ISTS Enhancement date in some cases.  When editing an item, IN-B currently reads:
  'IN-B Enter Inventory - Edit Existing Item Number - ISTS Enhancement 0'
 
I would vote to remove the word 'Enhancement' from the Titles; just leave 'ISTS mm/dd/yy'.
 
BTW:  The popup window that displays after selecting 'Part Type' is kind of goofed up.  It looks like it is missing it's bottom edge.

Thank you Allen for clarifying these fields for me. We do have ECO turned on.
 
We never used the UPC field, I was formally posting a Complaint (as a courtesy) were it would get some attention.
