## Display previous incident date for each problem (DAX)

Hi all,

Im new to this forum but would love it if someone could help me with a DAX question?

What i am trying to achieve is display the date of the previous incident at a problem level. So in ITIL you can have multiple incidents with the same root cause and they are grouped at a problem level (Many:1). I have created an index in DAX that displays the sequence in which that incident occurs i.e first is 1 second is 2 etc and will reset for each problem.

Data:

 Incident Number Date Problem Index INC1 1/1/2022 PRB A 1 INC2 1/2/2022 PRB A 2 INC3 1/3/2022 PRB A 3 INC4 1/4/2022 PRB B 1 INC5 1/5/2022 PRB B 2 INC6 1/6/2022 PRB B 3 INC7 1/6/2022 PRB C 1 INC8 1/7/2022 PRB D 1

Expected Result:

 Incident Number Date Problem Index Previous Incident Date INC1 1/1/2022 PRB A 1 INC2 1/2/2022 PRB A 2 1/1/2022 INC3 1/3/2022 PRB A 3 1/2/2022 INC4 1/14/2022 PRB B 1 INC5 1/15/2022 PRB B 2 1/14/2022 INC6 1/16/2022 PRB B 3 1/15/2022 INC7 1/16/2022 PRB C 1 INC8 1/17/2022 PRB D 1

I have found this post but doesnt work for what i need it to do.

Any help would be greatly appreciated as i have been struggling with this for the past month. Thanks

@LFORS , Create a new column

maxx(filter(Table, [problem] = earlier([problem]) && [date] < earlier([Date]) ) , [Date])
