Hi  @Anonymous ,

I created some data:

Here are the steps you can follow：

1. Create calculated column.

Month = YEAR('Table'[Sorted_onboard_date])&""&FORMAT('Table'[Sorted_onboard_date],"mm")

sum(request_headcount) =
SUMX(FILTER(ALL('Table'),'Table'[Month]=EARLIER('Table'[Month])),[request_headcount])

2. Create calculated table.

Table 2 =
SUMMARIZE('Table','Table'[Month],'Table'[sum(request_headcount)])

3. Result:

@Anonymous , You can datediff of the two date in a new column

datediff([Date1],[Date2], day)

If this does not help
Can you share sample data and sample output in table format? Or a sample pbix after removing sensitive data.

thanks, the requirement is need to add two fileds not one field, or may be a new table to be created

here is the original data,

I need  two column: sum(request_headcount) when month(sorted_onboard_date) = 202205 and 202205,

sum(request_headcount) when month(sorted_onboard_date) = 202204 ,202204

sum(request_headcount) when month(sorted_onboard_date) = 202205 ,202203

namely, I need to three values based on month(today) and return 2 columns to be shown to creat a visual:

month, sum(request_headcount)

202205           13

202204          23

202203          16
