I am new to Power BI and I am trying to get the last test value for a student where the test could have been taken multiple times. I need to omit the student if they only took the test once. There are row numbers per student in the table. The student number field is UMPI_NBR. the value I want is PHQ9_TOTAL and the row number field is TESTROW. All I am pulling right now is the largest value of all of the tests beyond the 1st one instead of the value of PHQ9_TOTAL of the MAX TESTROW.
Solved! Go to Solution.
This is working for me. I don't understand the syntax well enough to know why I don't need the UMPI_NBR specified in there somewhere.

Hi,
What do you mean by "I need to omit the student if they only took the test once"? Share a dataset and show the expected result.
Hi @Anonymous ,
I made a minor adjustment on the formula you provided , and now you should get the correct value, please check.
Last Visit = VAR a = MAX ( 'Table1'[UMPI_NBR] ) VAR b = SUMX ( VALUES ( Table1[UMPI_NBR] ), CALCULATE ( MAX ( Table1[PHQ9_TOTAL] ), DISTINCTCOUNT ( Table1[TESTROW] ) > 1 && 'Table1'[UMPI_NBR] = a ) ) RETURN b |

This answer gives me the next test score after the 1st one but not necessarily the last one.
Try like
//1
Last Visit = SUMX (
VALUES( Table1[UMPI_NBR] ),
CALCULATE (MAX(Table1[PHQ9_TOTAL] ), filter(Table1,Table1[TESTROW] = max(Table1[TESTROW])) ))
//2
rank = rank(Table1[UMPI_NBR],calculate(max(Table1[TESTROW])),,desc,dense)
Last Visit = SUMX (filter(Table1,[rank]=1),Table1[PHQ9_TOTAL] )

The 1st answer is close but I need to exclude the 1st score if the person hasn't taken a 2nd test.
The 2nd answer gives me syntax errors at '(' and most of the fields are highlighted as errors.
Hi @Anonymous ,
In fact , the formula I provided works well in my side... Here is the sample PBIX file I used , please check if there is any diffrence between yours and mine...
If I understand correctly , what you want to get is the total score of the best results of those students that took the test of multiple times. So I got the result by the following steps :
1 . Exclude students that take the test only once
2 . Get the best results from / of students that took the test of multiple times
3 . Summarize the scores obtained above .
For example , the following example contains the test scores of 5 students (S01 ~ S05 ) . Student S01 and S04 took the test only once , so the score of this two students are excluded . In addition , the best scores of S2 , S3 , and S5 are 89 , 82 , and 65 separately . Then the final summarized score is 89 + 82 + 65 = 325 .
Best Regards

Hi @yingyinr , @Ashish_Mathur , @amitchandak
1. Yes, I want to exclude the score of the students that took the test only once because one of the things I will be using the score for is to check the effectiveness of a training program. So I need to know if the score improved or not. So the ones that have only taken the test once, need to be excluded.
2. I want only the LAST score, not the best one and not a summary. So if student 'A' took the test 6 times:
TESTROW/PHQ9_TOTAL
1 80
2 85
3 70
4 80
5 90
6 68
I need the #6 - 68
Can you share sample data and sample output.Thanks.
