Dynamic Rename the most recent month

[Alexo_142]

The data source is appending the most current month on to the end of my data every month. I need to sum the column of the most recent month. For example today i need to sum YTD May but this time next month i will need to sum YTD June. I would like the rename the most current month "current month and then Sum that. if you have any other ideas im open to that also

Hello @Alexo_142 

Great question, if I've understood you correctly, you're trying to rename the column referencing last month, with the prefix "YTD ". Then sum the renamed column. I have tried to find an answer below:

For reference, I have used some dummy data based on the image you provided:

1) I started by using the formula tool to find todays date, minus one month. The function is:

DateTimeAdd(DateTimeToday(), -1, "Month")


2) Use the data time tool to extract out the 3 digit month (i,e Jan, Feb.....)

3) Prefix this month with the letters "YTD "

4) Create a column with the new column name in this case I chose "Current Month"

5) Drop unnecessary columns to get the following:

6) Feed this information, and the main data set, into the dynamic rename tool and configure it to take field names from right input rows:

This resulted in the following table:

7) Sum the column called current month.

Here is an image of the whole workflow:

I have attached a copy of the workflow below. Please let me know how you get on.
