Good morning, in my dataset the are two columns (“T040” and “T041”) that contains temperature values. I would like to remove all the rows where T040 and T041 are equals to the previous row. I need something like this: Original dataset TimeStamp T040 T041 16:15:00 28.3 27.8 16:15:01 28…

Hello @egobbo . You can also create calculated fields at the dataset level and then create a filter at the dataset level as well. This way you can filter the data directly there and make sure that all the analyses that use it received the filtered data. However remember that it is the best practi…

You can do a lag function and a first value function for both columns T040 & T041 Here is how it would work for t040 (you would also do this for t041: is_duplicate_t040 = ifelse(lead({t040},[{timestamp} ASC],1)=firstValue({t040]},[{timestamp} ASC],[{timestamp}]),‘Duplicate’,‘Keep’) Then you would…

Thanks for the reply, but I have already tried your idea without luck. I don’t need a filter on the dashboard, I need less data in the dataset. Let me be more detailed. I create a calculate fields like this vibrationMaxValue = maxOver({l3dspmaxvalue},[{t042}],PRE_FILTER) In this way vibrationMa…

@EnriqueS thank you very much!! As first step I will setup filters in a not-so-best-practice way, in the meantime I will study Glue and use it as soon as I will be ready. The Glue way is absolutelly the correct one, and I think I will use it a lot in the future. Thanks Enrico

Do you launch this code in quicksight or do you do it in sql? is_duplicate_t040 = ifelse(lead({t040},[{timestamp} ASC],1)=firstValue({t040]},[{timestamp} ASC],[{timestamp}]),‘Duplicate’,‘Keep’)
