Hello,

I need custome column in PQ, where I have already "Date" column.

If month is 2 (Feb.) to 11 (Nov.), result is the 1st day of previous month, same year, .

If monthe is 1 (Jan.), result is the 1st day, of month 12 (Dec.), last year.

Please help with the correct "if" query

Hi @RafaelAri ,
You can add a custom column and try this ,

if Date.Month([Date]) = 1 then #date(Date.Year([Date])-1, 12, 1) else #date(Date.Year([Date]), Date.Month([Date])-1, 1))

Hi @RafaelAri

You can try

Date.From(Date.StartOfMonth(Date.AddMonths([Date], -1)))

Hope this helps

Joe
