e matching cases by.
Cases are considered duplicates if their values match for
all selected variables. If you want to identify only cases that are a 100% match in
all respects, select all of the variables.
Sort within matching groups by. Cases are automatically sorted by the variables that
defin
e matching cases. You can select additional sorting variables that will determine
the sequential order of cases in each matching group.
For each sort variable, you can sort in ascending or descending order.
If you select multiple sort variables, cases are sorted by each variable within
cate
gories of the preceding variable in the list. For example, if you select date as
the first sorting variable and amount as the second sorting variable, cases will be
sorted by amount within each date.
