Pre-requisite to complete this : Alteryx Predictive Tools with R 4.0.5 needs to be installed to allow you to access ARIMA tools in Alteryx.

Step 1 :
Figure out filling the weeks and then after they've been appended using UNION, do the same for the weeks of the missing months.

The average is an average of the weeks' data; not months' data.

a) And you're filling the missing / nulls with the intra month weekly average and then
b) the month(s) with all weeks missing values with the monthly average.

Step 2 :

Use the ARIMA function and use the output of O for both tools.
We're working with weekly.

note : I peaked at Nicole Johnsons work since I thought the R link would work. It didn't :-( Use the O.

Never used the time series tools before.  Nice to see that they are pretty simple.
