Remove Duplicates on one column without removing whole record

Question

Hi,

How do I remove repeating cells from one column (measure) without removing the whole row? I would like to replace with null any repeating cell (sometimes there are triple or even four records). I used a multi-row tool, but that would only remove the duplicate, not if there are more than two of the same records for this specific attribute.

Thank you!

Do this in 2 steps:

Step 1: Identify the duplicate:

- Sort the data by the relevant column

- Use the Multi-row tool to check for duplicates and create a column called "isDuplicate" which is Y/N

Step 2: Eliminate the duplicate

- Simple formula tool to update FieldName field that says "if [isDuplicate] = 'Y' then null() else [fieldname] endif"

Hi @magsbiel

I believe the Multi-Row Formula Tool is still what you want to use. You can define what fields (attributes) you want it to be evaluated on by selecting it in the "Group by" section.

Can you share a dummy file or illustration of what you're working with and what you'd like it to look like after?
