append Tableau input under condition

[aurora9003]

Hello Community,

I am new here, and I have the following issue with my workflow:

It is scheduled in the gallery one time a day. Each time it overwrites a Tableau input file.

But I would like to store data from each 20th day of the month, meaning - there is a data column filled in by function: DateTimeToday(),

and there is a solution which detects whether today is the 20th calendar day and if so --> append Tableau input if not --> replaces yesterdays data with today's.

So, in the end, I have all the 20th calendar day data and today's data. Today's data will be replaced by tomorrow's data unless it is not the 20th. And so on and so forth.
