Count the number of rows with the PID value equal to current row's UID

[Bogdan-Ciocoiu]

Hello community -- I have a table below, and I need to calculate the last column as a custom measure/custom column. I'm grateful for any advice concerning the formulae. Please note this is a single table. The last column counts the number of rows which have as PID, the respective row's UID.

ID	PID	Count rows
1		2
2	1	1
3	1	0
4		0
5	2	0

Many thanks for considering my request.

Best wishes,

I can confirm that by creating a second Power BI data set (by loading, again, the same SP list) works.

I found the answer:

Create a second identical SharePoint list and use the below.

Additional column =

    calculate (

        COUNTROWS('SharePoint list (replica)'),

        FILTER('SharePoint list (replica)','SharePoint list (replica)'[PID]='SharePoint list'[ID])

    )

Step 1: Create a summarized table to fetch the count of PID

          Table 2 = SUMMARIZE('Table','Table'[PId],"COUNT",count('Table'[PId]))

Step 2: Join the main table to the Summarized table (Table 2) using the column "ID" (Table 2(PID) --> Main Table(ID))

Step 3: Create the tablular visual for ID,PID from Main table and the "count" column from the Summarised table.

Step 4: Enable "Show items with no data" for ID.

Hello,

Can someone confirm what the syntax would be if PID and UID were columns in the same SharePoint list, please? I think this is the key.

Count Measure =
VAR __id = MAX ( PID[ID] )
RETURN
CALCULATE (
COUNTROWS ( PID ),
ALL ( PID ),
TREATAS ( { __id }, PID[PID] )
) + 0

Hello Parry, thank you for your swift reply. I'm facing a few challenges due to my setup being slightly different from the one presented above. I'm using Power BI Desktop 2.83, and I'm pulling data from a SharePoint site. My columns are not titled ID and PID; for me to call them, I would have to use something like:

'SharePoint list name'[PID column name] instead of PID

When I start converting this MAX ( PID[ID] ), I get the red error market under PID(ID), and no matter how I refer to my actual column title, I can't seem to be able to get rid of the error. I tried:

'SharePoint list name'[PID column name] ['SharePoint list name'[ID column name] ]

Is there an alternative way, I might be able to pull this off, without calling this syntax: PID[ID]?

Thank you,

Bogdan Ciocoiu

@Bogdan-Ciocoiu add following measure

Count Measure = 
VAR __id = MAX ( PID[ID] )
RETURN
CALCULATE (
    COUNTROWS ( PID ),
    ALL ( PID ),
    TREATAS ( { __id }, PID[PID] )
) + 0

I think the issue is that my MAX() accepts only one column as parameter, while you're saying MAX (PID[ID]) and I don't think that PID[ID] works with SharePoint lists. Can you confirm, please how would the entire syntax look like with SharePoint lists?
