How to find the last non blank value in a row (similar to lookup function in excel)


Hi everyone,


I am currently trying to analyse a large data set of daily payments for individual clients (refer to attached file for a small sample of the data). The goal is to see the last payment date (if any) for each individual client. I have done this in the excel sample (with lookup value formula) and would like to replicate the results in Alteryx, in order to apply to the entire data set. 


Any help would be much appreciated. Thank you in advance.




Hi @Naka!


I was able to replicate your results in the attached workflow. The key was to use a Transpose tool then summarize your data from there. I used a Join at the end to get all of the input data back.


Hope this helps!

The Transpose tool help to transform the payment dates to rows to determine the total payments and last date. Then those values are joined back to the original data in my attached solution. Let me know if you have any questions.

I'd be interested to know if this solves your question. I used Transpose, but then combined with the Unique tool.




Hey @Naka


For future reference, it's actually really easy to open a workflow that's in a newer version of Alteryx than the one you're using. 


Simply right click on the workflow before opening it and select 'Edit with Notepad++.' From here, on line two , change the yxmdVer to the version of Alteryx you are using. Save, close, and viola. You should then be able to open the workflow without issues.
