ANALYSIS TABLE/COUNTX FUNCTION

[colsand]

I am trying to create a small analysis table which gives a breakdown of the number of items which fall within certain lead times.. In excel, this would be a simple matter of using COUNTIF/COUNTIFS but i am struggling to re-create this in Power BI.  I've tried using the COUNTX function, but although this doesn't give me an error message when I create the measure, it does when I try and put this in a visual.

I'm aware that there is probably a better way to achieve what I'n trying to do, so would appreciate some guidance about the best way to do this.

This is the output I am trying to achieve:

Cluster LT (days)			# Line Items
Less Than 10	1,617
11 - 20	588
21 - 30	600
31 - 50	842
51 - 90	776
> 90	617
Negative LT	14
Total	5,054

What I am trying to do is count the number of items which have lead times in these categories.

Any help would be greatly appreciated.

TIA.

Hey,

I don't think you want to use the COUNTIF function for this specific problem.
The better alternative is probably to use CALCULATE or IF depending on your preference.
A measure for the date 11-20 would probably look something like the following:

Measure for 11-20 = CALCULATE(SUM(Table1[Amount]);Table1[Days] = "11-20")

Hi @colsand

Such segmentation/ banding is easily achieved using a PARAMETER TABLE in Power BI

See the attached file using your sample data

Here are the steps

Create a parameter table with segements you desire

Cluster LT (days)	Start	End
Less Than 10	0	10
11 - 20	11	20
21 - 30	21	30
31 - 50	31	50
51 - 90	51	90
> 90	90	200
Negative LT	-1000	-1

Then you can add a Calculated Column for # of items within each segment/band as follows

# Line Items_ =
CALCULATE (
    COUNT ( MainTable[Line Items] ),
    FILTER (
        MainTable,
        MainTable[LT (days)] >= Parameter_Table[Start]
            && MainTable[LT (days)] <= Parameter_Table[End]
    )
)

I have got this to work, but it gives me totals based on all of the data in the table.  I have the rest of the report filtered by customer.  How do I make this filter apply to the parameter table?

Thank you.

Hi @colsand

Could you share your file please?

Or

Provide sample data and desired results

Hi,

I hope this link is OK.  https://onedrive.live.com/redir.aspx?cid=727fdb9e098e6580&resid=727FDB9E098E6580!17781&parId=727FDB9...

Hi @colsand

The solution to this is to go other way round

Instead of Pulling data from LT Data into Parameter Table..... Pull the Cluster name from Parameter Table into LT Data

Create a calculated Column in LT Data as follows

Cluster LT =
CALCULATE (
    VALUES ( Parameter_Table[Cluster LT (Days)] ),
    FILTER (
        Parameter_Table,
        'LT Data'[Lead Time] >= Parameter_Table[Start]
            && 'LT Data'[Lead Time] <= Parameter_Table[End]
    )
)

Please see your updated file here

Now you can use the Customers as filter/slicer

Many thanks for your help, that appears to be what I need.

Hi @colsand

I noticed that some of your Lead Times fall in none of the Clusters. For example Leadtime greater than 200

You can always go back and revise the Start and End ranges of your Parameter Table or Add new cluster

[colsand]

Yes, thank you, I will set the end point way over the maximum to allow for this.

Many thanks for your help.  I will give this a go this afternoon.  Unfotunately, my company's web security policy has blocked access to the attachment, so I will have to get this sorted out.
