DAX - Create measure to count Store type

[venug]

Hi Everyone,

Based on store type I need the count of unique outlets at month level ( this was done as it is a direct statement). However they want to implement having multiple months selection. While we select multiple month my categorical column store type will change based on  each month data. To overcome this problem planning to implement below logic, where I need your expertise.

1. Filter the data what is required( multiple month) – Table1
2. Remove the month column and come up with the unique store type based on below logic – Table2
3. When the store have same in both months the condition like below. - Table2
1. If store type is “New” in Jan and store type is “Retain” in Feb – the store should treat as “Retain”
2. If store type is “New” in Jan and store type is “Lapsed” in Feb – the store should treat as “Lapsed”
3. If store type is “Retained” in Jan and store type is “Retain” in Feb – the store should treat as “Retain”
4. Then count unique stores in each type as mentioned in the final output. – Table3

Table 1:

Store	Month	Store type
A	Jan	New
B	Jan	retain
C	Jan	retain
D	Jan	new
E	Jan	new
F	Jan	retain
G	Jan	lapsed
H	Jan	lapsed
A	Feb	retain
B	Feb	lapsed
C	Feb	retain
D	Feb	retain
L	Feb	new
M	Feb	retain
N	Feb	lapsed
T	Feb	retain

Output format (Table 2: )

E	new
F	retain
G	lapsed
H	lapsed
L	new
M	retain
N	lapsed
T	retain
A	retain
B	lapsed
C	retain
D	retain

Final Output (Table 3: )

Store Type	Count
lapsed	4
new	2
retain	6
Grand Total	12

Thanks in advance

Hi, @venug 

Based on your description, you can create the Table 2 and Table 3 as follows.

Table 2 =

SUMMARIZE (

    'Table 1',

    'Table 1'[Store],

    "Store type",

    VAR j =

        CALCULATE (

            MAX ( 'Table 1'[Store type] ),

            FILTER ( 'Table 1', 'Table 1'[Month] = "Jan" )

        )

    VAR k =

        CALCULATE (

            MAX ( 'Table 1'[Store type] ),

            FILTER ( 'Table 1', 'Table 1'[Month] = "Feb" )

        )

    RETURN

        IF (

            j = "new"

                && k = "retain",

            "Retain",

            IF (

                j = "new"

                    && k = "laspsed",

                "Lapsed",

                IF (

                    j = "retain"

                        && k = "retain",

                    "Retain",

                    IF ( k = "" || ISBLANK ( k ), j, k )

                )

            )

        )

)

Table 3 = SUMMARIZE(

    'Table 2',

    'Table 2'[Store type],

    "Count",

    COUNT('Table 2'[Store type])

)

Result:

Table 2:

Table 3:
