Hey @annzhu 



I generated some fake data to bring an example to you.

Look what I'd do:




- Here I have a Customer ID field. You could or could not have it, if you don't have a field like this, you can generate this with a RecordID tool, as @EstherB47 did.

- Dynamic Select your columns as I had previously shown it to you

- Tranpose your current month and previous month columns using Customer ID as key field

- Use Multi-Row formula to calculate difference. Set Values for Rows that don't exist to NULL and group by Customer ID.

- Filter out the non-null values

- Join this dataset to your original dataset before the transposing, to bring the Difference column.
