Tableau Interview Scenario working with Nulls, Missing Values

[@deepikaanugu6116]

Hi...I just watched this video and I have a requirement quite opposite to what you did. I need to filter out a category if there is no value in any one of the sub category(Product) for a given time frame. Can you tell me how to achieve this? i.e., only show the category that sold all the 3 products.

Sounds interesting need to try this

[@anushadavuluri5558]

Did u get the solution?

[@vasimahamadshaikh3730]

RAHUL BHAI please share table or data set with scenario for practice on that scenario.

[@dhivyasoruban4146]

I have used lookup with Zn in Sales & Profit, now I want to find the Profit ratio however am getting this error "Argument to sum (an argument function) is already an aggregation and cannot be further aggregated."

[@TechiRahul]

Ur field is already aggregated and on top of that u are trying to aggregate again that's the issue

Hi Rahul,
I am in the same scenario however can you try adding multiple filters to your bar chart and apply, for me only when a single filter is applied it works to show 0 and as soon as i apply another dim filter it goes blank. Thank you 💓.
