Find the previous action

Hello,

In power bi, I would like a column calculated in dax which puts a 1 on the last action which precedes the auto-close action of the same ID.
The table is called Journal, the time column is time, the column where we find the auto-close is called action.
I put an example of what I want.
Can you help me ?
THANKS

Good morning,
With the formula below, how to display only one 1; the one just after the auto-close?
Can anyone help me?

`Auto-close2 =

VAR _close_time = CALCULATE(MAX('journal'[created_at]),'journal'[action]="auto-close",ALLEXCEPT('journal','journal'[task_id]))
VAR _result =IF('journal'[created_at]=CALCULATE(MAX('journal'[created_at]),'journal'[created_at]<_close_time,ALLEXCEPT('journal','journal'[task_id])),1)
RETURN
_result`


Thanks in advance.

Good morning,
Let me come back to you because I'm still stuck.
I am looking to put the name of the agent in the column created in front of the line Journal[action]=auto-close which follows the line where I have the agent for the same task_id.

Hello @v-cgao-msft ,

Thanks a lot for your help.
Is it possible to have a 1 just on the action which precedes and not all the actions which precede.
THANKS

@v-cgao-msft This should be good.

Hi @MathieuF ,

 

It seems that the key [action] field is missing from the data.

Please try:

Column = 
VAR _close_time = CALCULATE(MAX('Table'[created_at]),'Table'[action]="auto-close",ALLEXCEPT('Table','Table'[ID]))
VAR _result =IF('Table'[created_at]=CALCULATE(MAX('Table'[created_at]),'Table'[created_at]<_close_time,ALLEXCEPT('Table','Table'[ID])),1)
RETURN
_result

@v-cgao-msft 

Thank you for your help, unfortunately, I have an error message:
It is not possible to determine a unique value for the "created_at" column of the "Journal" table. This can happen when a measure formula refers to a column that contains many values, without specifying an aggregation such as min, max, count, or sum to get a single result.

So I changed the query to 

 

Auto-close = 
VAR _close_time = CALCULATE(MAX('Journal'[created_at]),'Journal'[action]="auto-close",ALLEXCEPT('Journal','Journal'[id]))
VAR _result =IF(MAX('journal'[created_at])=CALCULATE(MAX('Journal'[created_at]),'Journal'[created_at]<_close_time,ALLEXCEPT('Journal','Journal'[id])),1)
RETURN
_result

 

is it good ?
Because I have no result 😞

hi @MathieuF 

try to add a calculated column like:

Column = 
VAR _LastTime=
    MAXX(
        FILTER(
            data,
            data[name]=EARLIER(data[name])
                &&data[action]<>"auto-close"
        ),
        data[time]
    )
RETURN
    IF(
        [Time]=_LastTime,
        1
    )

it worked like:

Hello @FreemanZ ,

Thank you very much, I will test.
Why does the formula include the name? Knowing that a person can have several IDs at the same time.
I think that it is rather necessary to insert the notion of ID.
Mat

hi @MathieuF 

you know your dataset best. please feel free to change name to id.

@FreemanZ 

The results are not good.
I am currently having a problem accessing the table.
When I have new access, I will see what is causing the problem.
Small question, should the table be sorted?

hi @MathieuF 

what error do you get?

Sort will not change anything in most DAX occassions.

Hello @FreemanZ 
I'll screenshot the problem for you.
I will privately send you the model with the data.
Is it related to the sorting of updated-at?
