Find the previous action

MathieuF — Thu, 27 Apr 2023 06:07:21 GMT

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

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.

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?

Hi MathieuF ,

Please try,

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

Hello Anonymous ,

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

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

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 😞

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.

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.
