get previous values per group

Hello everybody,
I would like to have the previous values ​​(see screenshot) displayed for the "ChangeWeek" column. So there should be a new column (see screenshot "new"), where the previous value per group (ISIN) is always displayed. It is important that it is a column, not a measure. I already got a solution in another post (https://community.powerbi.com/t5/Desktop/Get-weekly-values-and-previous-values/m-p/927847/highlight/...), but it's a measure there and not a column. Does anyone have a solution?

Re: get previous values per group

Try , as new columns

Column = maxx(filter('Table','Table'[ISIN]=EARLIER('Table'[ISIN]) && not(ISBLANK('Table'[ChangeWeek])) && 'Table'[Date]<EARLIER('Table'[Date])),'Table'[Date])

Column 2 = if(ISBLANK('Table'[ChangeWeek]),BLANK(),maxx(FILTER('Table','Table'[ISIN]=EARLIER('Table'[ISIN]) && ('Table'[Date])=EARLIER('Table'[Column])),('Table'[ChangeWeek])))

Re: get previous values per group

So generally you are going to do this with something like EARLIER - See my article on Mean Time Between Failure (MTBF) which uses EARLIER: http://community.powerbi.com/t5/Community-Blog/Mean-Time-Between-Failure-MTBF-and-Power-BI/ba-p/3395.... What is the measure calculation that fixed it? Should be very translatable to a column.

Re: get previous values per group

Hi @amitchandak ,

you're right. The screenshot is misleading. This screenshot should be better:
prevValues2.PNGdesired column "new"The column "new" consists of (always) the previous value. (based on column "ChangeWeek".
