Dear all
I am trying to return different value in a new column if I find a specific value in several rows.
For example, I am trying to return the earliest view date when I found "Contact Customer Service" for each case and return, and if there is no any "Contact Customer Service" for a case, return the last view date.
Is it possible to have this loop funtion in Power BI?
Case | Time_Stamp | Action | First or Last View |
X001 | 2/1/2021 | View | 2/1/2021 |
X001 | 2/3/2021 | View | 2/1/2021 |
X001 | 2/18/2021 | Place into Cart | 2/1/2021 |
X001 | 2/19/2021 | Contact Customer Service | 2/1/2021 |
X001 | 2/22/2021 | Cancel | 2/1/2021 |
X002 | 1/3/2021 | View | 1/3/2021 |
X002 | 1/19/2021 | Place into Cart | 1/3/2021 |
X002 | 2/3/2021 | Purchase | 1/3/2021 |

Thank you in advance!

View Date CC =
VAR __v =
FILTER(
'CASE',
'CASE'[Case] = EARLIER( 'CASE'[Case] ) && 'CASE'[Action] = "View"
)
RETURN
IF(
ISEMPTY(

MAXX( __v, 'CASE'[Time_Stamp] ),
MINX( __v, 'CASE'[Time_Stamp] )
)
Thanks to the great efforts by MS engineers to simplify syntax of DAX! Most beginners are SUCCESSFULLY MISLED to think that they could easily master DAX; but it turns out that the intricacy of the most frequently used RANKX() is still way beyond their comprehension! |

Thanks for your answer! Yet, there is an error "A circulated dependency was detected..." now.
In your file, this error is not found, but the result seems different. 😞
Could you kindly take another look? Much appreciated!

The
MAXX( __v, 'CASE'[Time_Stamp] ), MINX( __v, 'CASE'[Time_Stamp] )
The MINX should come first and MAXX come second, but this DAX and logic work for me. Thanks again!
