Sum values in Column C where the value in Column B matches value in Column A

[duane1]

Hi.

In my table below, I would like to sum the values in "FROM_COUNT2" where the value in "FROM_PRODUCTID" matches the vaue in "TO_PRODUCTID".  In this example, the TO_COUNT2 column should contain the sum of all the FROM_COUNT2 values where the TO_PRODUCTID matches the FROM_PRODUCTID.  In excel, I would use SUMIF to do this easily.  Sometimes, there is more than one value in the TO_PRODUCTID that matches the FROM_PRODUCTID.

This is in Power Pivot but I assume the same formula I would use in other power platforms like BI or query.  Let me know if it should be posted elsewhere.  Thanks.

Hi @duane1 ,

Would you like to achieve the following results?

Please try to add a new column and use the code below.

TO_COUNT2 = 
CALCULATE(
    SUM(TEST[FROM_COUNT2]),
    FILTER(
        TEST,
        TEST[TO_PRODUCTID] = EARLIER(TEST[FROM_PRODUCTID])
    )
)

Could you please provide example data or sample files here if you have any confused? We could offer you more help if we have information in detail. There is sensitive data that can be removed in advance. How to provide sample data in the Power BI Forum - Microsoft Fabric Community

Hi @duane1 ,

Create a new calculated column using this DAX:

TO_COUNT2 = 
CALCULATE(
    SUM(TableName[FROM_COUNT2]),
    FILTER(
        TableName,
        TableName[TO_PRODUCTID] = EARLIER(TableName[FROM_PRODUCTID])
    )
)

Replace table and columns names with your owns

Thanks, this is what worked.  I received the same help from another.

Thanks, this worked.  I had a feeling EARLIER was involved.  I was learning about it.  This is the solution.

EARLIER is a legacy function, and not recommended. Use variables.
