Max Negavtive value

[OscarSuarez10]

Hello I want to get the max negative value (PRODUCTION) for each FILE and ID, How can I do this using DAX?

Max for FILE 0 ID 12 = -70

Max for FILE 1 ID 13 = -1

Max for FILE 2 ID 14 = -46

FILE	ID	PRODUCTION
0	12	-82
0	12	-70
0	12	10
1	13	-10
1	13	-1
1	13	50
2	14	-78
2	14	-46
2	14	1

Hi @OscarSuarez10 ,

Try this: 

Max neg value for each ID File =
CALCULATE (
    MAX ( prod[PRODUCTION] ),
    FILTER ( ALLEXCEPT ( prod, prod[FILE], prod[ID] ), prod[PRODUCTION] < 0 )
)

Glad you include expected output!
Let me know if you have any questions.

If this solves your issues, please mark it as the solution, so that others can find it easily. Kudos are nice too.

In that case simply use:

Max Negative Value = MIN(PRODUCTION)
