Help with SUMMARISE measure

[PaulHallam]

Hi,

I have the following table 'DATA'

CATEGORY	ITEM	DATETIME	VALUES
1	A	01/01/2020 09:00:00	1
1	A	01/01/2020 09:00:00	0
1	A	01/01/2020 09:00:00	1
1	A	01/01/2020 09:00:00	0
1	B	01/01/2020 09:00:00	0
1	B	01/01/2020 09:00:00	0
1	B	01/01/2020 09:00:00	0
1	B	01/01/2020 09:00:00	0
1	A	01/01/2020 09:05:00	1
1	A	01/01/2020 09:05:00	1
1	A	01/01/2020 09:05:00	1
1	A	01/01/2020 09:05:00	0
1	B	01/01/2020 09:05:00	0
1	B	01/01/2020 09:05:00	0
1	B	01/01/2020 09:05:00	0
1	B	01/01/2020 09:05:00	1
1	A	01/01/2020 09:10:00	0
1	A	01/01/2020 09:10:00	0
1	A	01/01/2020 09:10:00	0
1	A	01/01/2020 09:10:00	0
1	B	01/01/2020 09:10:00	0
1	B	01/01/2020 09:10:00	0
1	B	01/01/2020 09:10:00	0
1	B	01/01/2020 09:10:00	0

If the sum of the [VALUES] for an [ITEM] in any given 5 minute period >0 then the [ITEM] is deemed to have been used, so effectively creating this table below;

CATEGORY	ITEM	DATETIME	VALUE
1	A	01/01/2020 09:00:00	1
1	B	01/01/2020 09:00:00	0
1	A	01/01/2020 09:05:00	1
1	B	01/01/2020 09:05:00	1
1	A	01/01/2020 09:10:00	0
1	B	01/01/2020 09:10:00	0

I want to know the utilisation of each item over the periods so;

ITEM A has been used on two of its three periods giving utilisation of 66.6%

ITEM B has been used on one of its three periods giving utilisation of 33.3%

Using this Measure in a matrix;

Utilisation% =
     (SUMX(
         SUMMARIZE(
            DATA,
            DATA[DATETIME],
                 "Count", if (SUM(DATA[VALUES])>0,1,if (SUM(DATA[VALUES])=0,0,0))),[Count]))/(DISTINCTCOUNT(DATA[DATETIME])*DISTINCTCOUNT(DATA[ITEM])

gives the correct utilisations at the individual [ITEM] level

BUT

at the [CATEGORY] level the measure is wrong showing 33.3% (2 uses out of 6) instead of (3 uses out of 6) 50.0%. This is because it is applying the measure at the [CATEGORY LEVEL] and when A & B are used together giving 2 uses at 09:005:00 it is converting this total to a 1.

Can anyone help to make the totals correct.

This looks like a measure totals problem. Very common. See my post about it here: https://community.powerbi.com/t5/DAX-Commands-and-Tips/Dealing-with-Measure-Totals/td-p/63376

Also, this Quick Measure, Measure Totals, The Final Word should get you what you need:

Thansk Greg,

All makes sense, but im having trouble with the measure to achieve the desired results. Fancy having a look and see if you can solve?

Appreciate any help at all
