Removing Duplicates with Condition
Hi All. My dataset have a lot of duplicate rows so I wanted to use "Remove Duplicates" in ETL based on the Shipment ID.
However, there are some products that are hazardous. I want to have the hazardous row left remaining when I remove the duplicates if there is a mix of Haz and non-Haz. Any function or use of "Rank & Window" I can use to have my desired output?
SAMPLE
Shipment ID vs Hazardous Tag
1 - Non-Haz
1 - Haz
1 - Non-Haz
2 - Non-Haz
2 - Non-Haz
3 - Haz
3 - Haz
4 - Non-Haz
4 - Non-Haz
4 - Haz
DESIRED OUTPUT
1 - Haz
2 - Non-Haz
3 - Haz
4 - Haz
Logic: When at least one is hazardous, return 1 line as hazardous

You can take the minimum value of your Haz / Non-Haz text in your rank and window to determine if had any Hazardous.
Alternatively, you can use a case statement to return 1 if the value is hazardous and 0 if it's not and then take the max of that value in your case statement and then convert it back to a text value using another formula tile.

@GrantSmith thank you sir! it worked! Did the ranking to put HAZ on top and when I removed duplicates, it's the one getting selected. :)
