Count appearance of string in a comma-separated data column does not count values after the first co

Anonymous — Fri, 03 Mar 2023 14:32:20 GMT

I have two tables:

Products table has a single column with one product per field:

List table has several columns but the column I'm interested in has fields that can have as little as one product to as much as 17, all separated with a comma and no spaces in between:

The issue I'm facing and need help with is to correctly count each product either, ideally as as a measure. I tried two measures but they both gave me an incorrect count of blanks; there are no blank values either table.
What I found is that both measures count only the *first* value they find in the List column and then continue counting subsequent rows:

How can I correctly count all values in each field from the List table and have zero "blank" counts?

Thanks!

Hi Anonymous

please try

Customer Products at M0 =
SUMX (
VALUES ( Products[Product] ),
SUMX (
VALUES ( Query1[M0_LIST] ),
INT ( CONTAINSSTRING ( Query1[M0_LIST], Products[Product] ) )
)
)

Hi Anonymous

If the same product is repeated multiple times inside the string and you want to consider that in the counting then please use

Customer Products at M0 = SUMX ( VALUES ( Products[Product] ), SUMX ( VALUES ( Query1[M0_LIST] ), VAR String = Query1[M0_LIST] VAR Items = SUBSTITUTE ( String, ",", "|" ) VAR Length = COALESCE ( PATHLENGTH ( Items ), 1 ) VAR T1 = GENERATESERIES ( 1, Length, 1 ) VAR T2 = SELECTCOLUMNS ( T1, "@Item", PATHITEM ( Items, [Value] ) ) RETURN COUNTROWS ( FILTER ( T2, [@Item] = Products[Product] ) ) ) )

Hi tamerj1 , thank you. I tried using the first measure and still gave me the incorrect counts, using the second one gave me this result.

The same product is not repeated inside the string, but two clients can definitely have the same products but they would be listed in different rows.

Can you please explain exactly what is the problem?

Hi tamerj1 , with your second measure I got a count of 1 for each product:

Also, the List table contains blank values/rows too, and as for active relationships I see that the Product and Lists table are connected in the Product[Products] column and the List[M0_LIST] column, one to many relationship. I don't know if this is causing the issue and hope this gives more clarity to my issue.

Please delete or deactivate that relationship or use

Customer Products at M0 = CALCULATE ( SUMX ( VALUES ( Products[Product] ), SUMX ( VALUES ( Query1[M0_LIST] ), INT ( CONTAINSSTRING ( Query1[M0_LIST], Products[Product] ) ) ) ), CROSSFILTER ( Query1[M0_LIST], Products[Product], NONE ) )
