Looking for records where two variables are swapped

[flyingfox]

Hi, I am trying to figure out how to implement this scenario with DAX.

Consider the following matrix with three columns

id	parameter	cost
AB	Parameter 1	10
AC	Parameter 2	20
AD	Parameter 3	15
CA	Parameter 4	40
EF	Parameter 6	67
FE	Parameter 7	80
EF	Parameter 8	45
GA	Parameter 9	45
CA	Parameter 5	52

The ID column is the concatenation of two variables that can be combined. I would like to find in the table all the records in which the two variables are swapped among each other.

The final result needs to be

id	parameter	cost
AC	Parameter 2	20
CA	Parameter 4	40
CA	Parameter 5	52
EF	Parameter 6	67
FE	Parameter 7	80
EF	Parameter 8	45

Thank you for your support

I set up the secondary key in the model. It works. Thank you

Hi, @flyingfox 

You can try the following methods.

Column:

id2 = RIGHT('Table'[id],1)&LEFT('Table'[id],1)

Table:

New Table = UNION(VALUES('Table'[id]),VALUES('Table'[id2]))

Measure:

Count id =
CALCULATE (
    COUNT ( 'New Table'[id] ),
    FILTER ( ALL ( 'New Table' ), [id] = SELECTEDVALUE ( 'New Table'[id] ) )
)

Measure = IF([Count id]=1,0,1)

Drag Measure into the view to be displayed and set it equal to 1.

Is this the result you expect?

Dear Team_Charlotte,

thank you so much for your valuable support. You undestood my issue and you almost got the result because, I am sorry, I did not mention that each record in the master Table is associated to a date. Therefore dragging your interesting Measure into the view to be displayed and setting it equal to 1, it does not produce the desidered results because the filter does not work due to the missing date in the New Table. Could you help me, please?
