Assigning Groups to Consecutive Values

[gg1234]

Hi everyone,

I need help solving a data analysis problem and was hoping to get some advice from the community. I have a dataset with two columns:

1. id: an identifier that is the same for all rows (e.g., "Prod 16Media 12").

2. GroupKey: a sequence of integers, not always consecutive.

I want to add a third column called ExpectedResult, as shown in the example below, which assigns the same group to consecutive values in the GroupKey column. When the values are not consecutive, it should start a new group.

Could someone suggest how to calculate the ExpectedResult column using DAX? Any advice would be greatly appreciated!

Thanks a lot in advance!

you can try this

Column =

var _last=maxx(FILTER('Table','Table'[id]=EARLIER('Table'[id])&&'Table'[GroupKey]<EARLIER('Table'[GroupKey])),'Table'[GroupKey])

return if(ISBLANK(_last),1,if('Table'[GroupKey]-_last=1,0,1))

Column 2 = sumx(FILTER('Table','Table'[id]=EARLIER('Table'[id])&&'Table'[GroupKey]<=EARLIER('Table'[GroupKey])),'Table'[Column])
