Earlier Function

[Anonymous]

Hi. I need to create a new column with the end date of that phase. The end of that phase is indicated by the complete state. the table would be similar to this but with more lines. Any idea how to get it.

Person	Phase	Status	DateTime
Peter	Sleeping	Running	04/03/2019 13:06
Peter	Sleeping	Running	04/03/2019 13:07
Peter	Sleeping	Complete	04/03/2019 13:08
John	Eating	Running	05/03/2019 14:06
John	Eating	Complete	05/03/2019 14:26
Marcus	Studying	Running	07/03/2019 15:16
Marcus	Eating	Running	07/03/2019 15:45
Marcus	Studying	Complete	07/03/2019 15:46
Marcus	Eating	Complete	07/03/2019 15:56

Hi there, basically you can use EARLIER here. This function is explained fully in this video with practical examples. Nowadays we use variables vastly to replace EARLIER but learing this function helps deepen your DAX a lot:

Hi, @Anonymous 

Based on your description, I created data to reproduce your scenario. The pbix file is attached in the end.

Table:

You may create a calculated column as below.

End Date = 
CALCULATE(
    MIN('Table'[DateTime]),
    FILTER(
        ALL('Table'),
        'Table'[Person]=EARLIER('Table'[Person])&&
        'Table'[Phase]=EARLIER('Table'[Phase])&&
        'Table'[Status]="Complete"&&
        'Table'[DateTime]>=EARLIER('Table'[DateTime])
    )
)

Result:

Best Regards

Hi @Anonymous ,

Not very clear.

YOu can try

New Column = CALCULATE(MAX(Table[DateTime] , Filter(Table, Table[Name] =earlier(Table[Name]) && Table[Phase] =earlier(Table[Phase]) && Table [Status]="Complete"))

New Column = Calculate (MAX(Table[DateTime]), Table[Status] = "Complete")

Else

New Column = IF( Table[Status] = "Complete", Table[DateTime] , BLANK())

@Anonymous , try new column like

maxx(filter(Table, [Name] =earlier([Name]) && [Phase] =earlier([Phase]) && [Status]="Complete"),[DateTime])

or

maxx(filter(Table, [Phase] =earlier([Phase]) && [Status]="Complete"),[DateTime])

Thank you for the prompt response. I have to make a status bar. That's why I need to know the start time and the end time of a phase. The maxx(filter(Table, [Phase] ?earlier([Phase]) && [Status]"Complete"),[DateTime]) function would solve the problem if that phase only occurred once, but in my case that phase occurs in several days and on some days several times during that day. So the maxx(filter(Table, [Phase] ?earlier([Phase]) && [Status]"Complete"),[DateTime]) function would give me the maximum date of the last time the phase is completed. Any idea for that every time there is that phase me from the date of the next state completed that phase? Thanks for the help.
