Validate data in a range is exactly the same for values in column

[Guest]

I want to identify duplicate values in column K. I then want to compare cell
differences on each column/row between the first occurence of a value to
subsequent occurences of the same value. I want to have a list showing what
the value was in row K, the row numbers they occur on, and what the
differences were on the subsequent rows. If there are no differences then I
don't want to know.

One note the range of cells on each row is constant.

Can you elucidate a little on this:

compare cell differences on each column/row between
the first occurence of a value to subsequent occurences
of the same value.

In the excel spreadsheet we have many items in a Bill of material structure.
These items can repeat throughout the spreadsheet depending where the item is
needed. We use this to load information to a database (oracle). The way the
upload works is that the first occurence of an item and all of its values on
the row lets say K7Q7 are loaded to the database. Every other occurence of
the item description should have identical values for all of it's
columns-for consistency sake, but these values do not overwrite the values
from the first occurence. So say item K appears on Row 7 and the description
is in column K, the rest of the columns are item attributes for the item
description. If the item description also appears on row 23 of column K then
all values in columns LQ in the second occurence of the item description
needs to be the same. If not then I would like to know what and where the
difference is on the second occurrence so I can inquire to why the values are
different-
