Hello:
I have the sample dataset list below. I would like to remove the duplicates of "Group" of (100, 200, 300 and 400) if I could find the
same text in the subgroup of 101-199, 201-299, 301-399 or 401-499. Please help. Thanks.

Alternativly to line:
input Group_code 1. @-1 Group 3. Class : $20. Component : $20. Product : $20.;
use:
input Group Class : $20. Component : $20. Product : $20.;
group_code = int(group/100);
