Alternative to SUMMARIZECOLUMNS

[vincentakatoh]

Hi, 

Currently, I'm using NewTable, SummarizeColumns to calculate a cummulative yield. 

Que: Is there any other method to calculate the "Yield" without using Newtable, SummariseColumns.

Will like to achieve the "Yield" calculation using the original table. This way, I can retain fields in the orignal table and add new filters for each fields.

In the summarizecolums, the fields are limited to area, line and station. And any new fields that are added to the summarizecolumns impact the way "Yield" is calculated. 

Yield Roll Table = 
    SUMMARIZECOLUMNS(
        data[Area],
        data[Line],
        data[station],
        "Count of Pass",COUNTROWS(FILTer('data',[test results]="P")),
        "Count of Fail",COUNTROWS(FILTer('data',[test results]="F")),
        "Yield",DIVIDE([CountPass],[CountPass]+[CountFail],1)
        )

New measure

Roll Yeild = PRODUCT([Yield])

Hi @vincentakatoh,

You can still get the desired yield value via creating measures without creating new table using SUMMARIZECOLUMNS.

CountFail = COUNTROWS(FILTER('data', [test results] = ("f")))
CountPass = COUNTROWS(FILTER('data', [test results] = ("p")))
Yield = DIVIDE([CountPass],([CountPass]+[CountFail]),0)

You can directly add measure [YieID] into value area in a matrix. Also, I noticed that above measure are all existing in the pbix file from the link you provided.

Hi @v-yulgu-msft, 

The problem is a with the cummulative calcuation. Line 1 Yield is a product of Station 1 and Station 2 yield. 

Line1 Yield = S1 yield (66.7%) * S2 Yield (33.3%) = 22.2% (achievable using SummariseColumns). 

Nonetheless, if by using a simple measure Line 1 Yield will be a count of all F and P in S1 and S2.

Hi @vincentakatoh,

As you need to get the ummulative calcuation via Product function, and we can only add a column inside this function, personally, I think creating a new column to get the Yield first might be a best choice. If you don't wat to create new table via SUMMARIZECOLLUMNs, you could directly create Yield column in source table.

Hi @v-yulgu-msft, 

Can advise how to write the DAX (for the cummulative calculation)? How has to be done using M in Query Editor? Will be really great if you can provide the PBI file using below link (contributed by @Phil_Seamark). It has the values using SummariseColumns, the objective is to get the same results using new column (in same table).
