Row Generator - Add Rows for Missing Dates within a Range

Question

Alteryx Community,

I am trying to leverage the "Generate Rows" tool to add (missing) dates to my data set. The goal is to have a row for every single day that falls within the min/max date range of a given project ID. The visual will make it easier-

Desired Data Output (the grey rows are the rows I would like to have added):

Thank you,

Felix

the attached workflow should get you there.

The generate rows tool in your case would need to know the minimum and maximum date for each product ID. After that, join back to your original dataset and use the multi-row formula tool to fill in the gaps.

Hi @felixcaspari

My go at a solution for you. I also used the MultiRow formula tool, like @brindhan. Just simplified the formula a bit. You can use <, >, and = when comparing dates in Alteryx.

My formula:
IF [DateTime_Out]<=[Row+1:DateTime_Out] THEN [Row+1:DateTime_Out]
ELSE [DateTime_Out] endif

Also included a few tools to return the date to the original text format if desired.

Cheers!
