Compare one column to all the others

[thiagofnds]

Hello!

I am not sure if this is the best way of doing this but I have 2 different tables, one with a reference and the other one with the evaluation of the people. I need to compare the evaluation column of each person to one of the activities reference in the other table and then give a grade to each person accordingly to the evaluation. In table 2 we just have binary evaluation, someone has or not a skill, table 2 has levels, 0, 1, 2 and 3. I am just adding some data similar to what I have.

Table 1 - Reference 

Skill code	Activitie 1	Activitie 2
CG002.9	3	2
CG001.10	2	2
CG002.2	1	0

Table 2 - People

Skill	Person 1	Person 2	Person 3
CG002.9	1	0	1
CG001.10	1	0	1
CG002.13	1	0	1
CG002.7	0	0	1
CG002.2	0	1	1
CG001.1	0	0	0

What I need is to compare each column in table 2 to all columns in table 1 and have this result for each person and each activitie:

Person 1 doesn't have all level 1 skills for activitie 1 

Person 2 has all level 1 skills for activitie 1

Person 3 has all level 1 skills for activitie 1

Thanks in advance

Thank you very much for your reply.

Well, I think it solves part of the problem. Actually the goal is to check if, for example, Person 1 has all Level 1 skills for activitie 1. Then do it to all other people and activitie levels and give them grades based on these criteria:

If (has all level 2 and level 3) -> min_grade = 7

esleif(has all level 3) -> min_grade = 4

else -> min_grade = 0

grade = min_grade + 3*(all level 1 that a person has)/(all level 1 of the activitie)

So that the max grade would be 10.

The result table should be something like this (with random numbers for grades here as example):

Person	Activitie 1	Activitie 2	Activitie 3
Person 1	7	10	4
Person 2	1	5	4,5
Person 3	3	8	7,8

I did it on Excel (a not very elegant or automated (but easy) solution) but it seems to be way harder to do in Power BI.

I used the formula below to each grade, where colums A to DY are the activities and DY until the end are the people:

=IFERROR(IF(COUNT.IF(Compilado!A2:A1117;"3";Compilado!$DY$2:$DY$1117;1)+COUNT.IF(Compilado!A2:A1117;"2";Compilado!$DY$2:$DY$1117;1)>=CONT.IF(Compilado!A2:A1117;"3")+CONT.IF(Compilado!A2:A1117;"2");7;
IF(COUNT.IF(Compilado!A2:A1117;"3";Compilado!$DY$2:$DY$1117;1)>=CONT.IF(Compilado!A2:A1117;"3");4;0)) +
3*COUNT.IF(Compilado!A2:A1117;"1";Compilado!$DY$2:$DY$1117;1)/CONT.IF(Compilado!A2:A1117;"1");0)

Hi @thiagofnds ,

Please unpivot columns for ‘people’ table in Power Query like shown below:

You will get a table like this:

The relationship between two tables:

Please try following DAX to create a measure:

Measure = 
VAR _VALUE = SELECTEDVALUE('People'[Value])
VAR _ACT = MAX('Reference'[Activitie 1])
RETURN
IF(_VALUE = 1, _ACT)

Create a table visual, you can give a grade to each person accordingly to the evaluation.

If I misunderstand your demands, please feel free to contact us in time.

Best regards,
