Hi Gabriela,

I'd suggest to make a new column in the same collection. In the new column you combine all data from the other columns, eg Elena48Red and Miguel28Orange. You will end up getting two rows with Ray58Blue. Then you proceed to remove any rows that are duplicates in the new column. When this is done, you can remove the new column. All of this can be done in BP without the need of a Code stage.

No doubt, someone else will shortly post the code to accomplish the same. 🙂

Happy Coding!

Hi @Gabriela Esquivel,

You can remove the Field Name input parameter and modify your code in the following way:

Dim uniqueRows = (From row In Input_Collection.AsEnumerable()
                  Group row By a = String.Join(", ", row.ItemArray) Into grp = Group
                  Where grp.Count = 1
                  Select grp.First()).ToList()

Output_Collection = uniqueRows.CopyToDataTable()​

​

This way your grouping would be independent of any specific column and will take all column fields as grouping parameter.
