I'd like to show a minimum value relationship per part.
The data I'm working with has a four level data hierachy per group.
Starting with the Group Name.
I need the min value down to the lowest hiercharchy per group pre exercise.
The group is then exercised.
I need the min value down to the lowest hiercharchy per group post exercise.
I take the delta between pre and post exercise: Delta = min(table[Pre Value]) - min(table[PostValue])
The problem arises is when I want to show this in a regular table. I have to add the columns of each data level in the hierarchy to show the smallest and largest delta. I don't want to show all the levels in the hierachy in the table.
Basically show Group Name and Largest Delta and Smallest Delta.
I need a measure that will maintain the data hierachry down to the lowest level.
This is the only way I know how to get this to work. Is to reveal each data level in the hiearchy. (Drill Down)
This measure works fine with the table below, but shows way too much unwanted information.
Delta = min(table[Pre Value]) - min(table[PostValue])
Device | Level1 | Level2 | Level3 | Level4 | Pre Value | PostValue | Delta |
A | 0 | 0 | 0 | 0 | 1000 | 1050 | -50 |
A | 0 | 1 | 0 | 1 | 999 | 899 | 100 |
A | 1 | 0 | 0 | 0 | 1010 | 1000 | 10 |
A | 1 | 1 | 0 | 1 | 800 | 770 | 30 |
B | 0 | 0 | 0 | 0 | 900 | 925 | -25 |
B | 0 | 1 | 0 | 1 | 750 | 800 | -50 |
B | 1 | 0 | 0 | 0 | 800 | 750 | 50 |
B | 1 | 1 | 0 | 1 | 575 | 550 | 25 |
What I need is a measure to condense and not show each level but maintain the hiearchy to the lowest level.
I do not know how to maintain or force hierchy level down to the lowest level using DAX.
This is what I need ideally with Min Delta and Max Delta as separate measures.
That way I can show both min or max Delta, or both.
Device | Level1 | Level2 | Level3 | Level4 | PreValue | PostValue | Delta Type | Delta |
A | 0 | 0 | 0 | 0 | 1000 | 1050 | min | -50 |
A | 0 | 1 | 0 | 1 | 999 | 899 | max | 100 |
B | 0 | 1 | 0 | 1 | 750 | 800 | min | -50 |
B | 1 | 0 | 0 | 0 | 800 | 750 | max | 50 |
I would settle for the table below if it's any easier.
Device | Delta Min | Delta Max |
A | -50 | 100 |
B | -50 | 50 |
Note:
PreValue is a measure.
PostValue is a measure
I've tried many DAX functions. Using All, All Except, All Selected, Filter and some combination thereof as well as other functions.
I need help from the experts.
Thank You.
Hi @roncruiser ,
Is this what you want? Please check the attached .pbix file.
Filter Measure =
VAR MIN_ =
MINX ( ALLEXCEPT ( 'Table', 'Table'[Device] ), [Delta Measure] )
VAR MAX_ =
MAXX ( ALLEXCEPT ( 'Table', 'Table'[Device] ), [Delta Measure] )
RETURN
IF ( [Delta Measure] = MIN_ || [Delta Measure] = MAX_, 1 )
Delta Max =
MAXX ( ALLEXCEPT ( 'Table', 'Table'[Device] ), [Delta Measure] )
Delta Min =
MINX ( ALLEXCEPT ( 'Table', 'Table'[Device] ), [Delta Measure] )
Best Regards,
Icey

Hi @Icey
I am looking at it now and trying to understand the logic behind your DAX measures and how it all works together. The data I posted in this thread is a basic format example of the real data but not the real data. The acutal data set is millions of rows deep. I will apply your measures to the real data and I will respond soon.
Thank You for taking the time @Icey
I would like like some help. Anyone care to chime in to at least discuss will be appreciated.
I was thinking maybe a helper table to begin with? Maybe a helper table is not needed. I am unsure.
Hope to hear from the forum.
Thank You.
