Switch and calculate

[Anonymous]

Hi everyone,

I am trying to calculate percentage total no of transactions occured across filters.

My data is as follows,

Hour	Weekname	Count_loading_col	Total_loading	Total teus	Location_name	Column
41	20WK24	0	0	90		0
4	20WK24			80		ND
	20WK24				a	ND
8	20WK24	0	0	90		0
71	20WK24	0	0	80	b	0
3	20WK24	22	1	90		1
21	20WK25	0	0	90		0
13	20WK25	0	0	88		0
	20WK25					ND
4	20WK25				c	ND
41	20WK25	0	0		d	0
7	20WK25	0	0			0
	20WK25					ND
47	20WK25	0	0	80	b	0
11	20WK25	0	0	80		0
23	20WK25	0	0		e	0
9	20WK25	0	0		b	0
15	20WK25	0	0		a	0
8	20WK25	0	0		a	0
2	20WK25	22	1			1
5	20WK25	0	0			0
	20WK25					ND
50	20WK25	0	0	90		0
16	20WK25	0	0		a	0
6	20WK25	0	0		c	0
6	20WK25	0	0		a	0

I want to calculate as follows,

For a week across different locations what is percentage.

1. First need to filter across location and weekname.

2. Check for overall count for that week and location. (Ex. b location has 10 counts in week 20WK25).

3. Have a condition with Hour <4, check for that particular condition in that week. (Ex. b location has passed 4 counts in week 20WK25).

4. Calculate percentage which step 3/step2.

How can I go about this?

Switch and calculate in measure is not working, if I do in calculated columns how can I go about it?

Thanks

Hi, @Anonymous 

Based on your description, I created data to reproduce your scenario. The pbix file is attached in the end.

Table:

You may create a measure as below.

Percenatage = 
var _table = ALLSELECTED('Table')
var tab = 
SUMMARIZE(
    'Table',
    'Table'[Weekname],
    "Result",
    var _weekname = [Weekname]
    var newtab = 
    SUMMARIZE(
        _table,
        'Table'[Hour],
        'Table'[Weekname],
        'Table'[Location_name],
        "flag",
        IF(
            'Table'[Hour]>4&&[Location_name]<>"",
            1,0
        )
    )
    return
    DIVIDE(
        CALCULATE(
            DISTINCTCOUNT('Table'[Location_name]),
            FILTER(
                  newtab,
                  'Table'[Weekname]=_weekname&&
                  [flag]=1
            )
        ),
        COUNTROWS(
            FILTER(
                newtab,
                [Weekname]=_weekname&&
                [Location_name]<>""
            )
        )
    )
)
return
SUMX(
    tab,
    [Result]
)

The overall count for '20WK25' with a location is 10. The distinct count location name with criteria of hour>4 for '20WK25' is 5. Here is the result.

If I misunderstand your thoughts, please show us your expected result. 

Best Regards

Allan

Thanks @v-alq-msft . It was very helpful.

Done following calculations,

Step 1:  created calculated column for hour.

Hour flag = SWITCH(TRUE(),

                'TATLOADING'[Hour]= BLANK(),0,

                'TATLOADING'[Hour]<4,1,

                'TATLOADING'[Hour]>=4,0)

Step 2: created calculated column for location and hour.

Location and Hour flag = SWITCH(TRUE(),

                        'TATLOADING'[Hour flag]=0 && TATLOADING[Location_name]="",0,

                        'TATLOADING'[Hour flag]=1 && TATLOADING[Location_name]="",0,

'TATLOADING'[Hour flag]=0 && TATLOADING[Location_name]<>"",0,

                        'TATLOADING'[Hour flag]=1 && TATLOADING[Location_name]<>"",1)

Step 3:Calculated percentage by using step 1 and step 2.

percentage = DIVIDE(SUM(TATLOADING[Location and Hour flag]),COUNTROWS(FILTER(TATLOADING,TATLOADING[Location_name]<>"")))

Thanks.

@Anonymous , not very clear.

do you wow comparision ?

@amitchandak, Thanks for your reply, I am not looking for that comparison, I am looking for calculation.

I want to calculate percentage across location and across weeks. Ex. 20Wk25 location a achieved 30% like that by using DAX.

My steps are

1. Calculate Overall count across week and location(Ex. location b has 10 counts in week 25)

2. Calculate count with criteria of hour>4. (Ex. location b has passed 5 transactions(counts) in week 25)

3. calculate percentage(Step2/Step1) for each location and week. My DAX should be dynamic so that I dont need to check for weeks everytime.

So I tried for started doing step 3,

count = SWITCH(TRUE(),

'TATLOADING'[Hour]<4 ||'TATLOADING'[Hour]=0,1,

'TATLOADING'[Hour]>=4,0)

This condition says if Hour>4, put it as 0 else if hour<4 and =0 put as 1.

Hereafter how can go about and calculate overall count and percentage Step1 and Step3?

Thanks.
