DAX Formula for Summarizing Transactions

Objective

To create a DAX formula that summarizes the total sales by partner from a given table containing transaction data.

DAX Formula

The following DAX formula computes the total sales grouped by the partner:

SalesSummaryByPartner = 
SUMMARIZE(
    YourTableName,
    YourTableName[Partner],
    "Total Sales", SUM(YourTableName[Sales])
)

Explanation of the Formula

1. SUMMARIZE Function:

   • This function creates a summary of a table based on the specified columns.
   • Syntax: SUMMARIZE(<table>, <groupBy_columnName>[, <groupBy_columnName>, ...], [<name>, <expression>]...)

2. Parameters:

   • YourTableName: This should be replaced with the actual name of the table that contains your transaction data.
   • YourTableName[Partner]: The column by which the summary is performed. All unique values in this column will become row headers in the summarized table.
   • "Total Sales": This is the name given to the new column that totals the sales.
   • SUM(YourTableName[Sales]): The aggregation expression calculates the total sales for each unique partner.

Practical Example

Assuming you have a table named Transactions with the following columns:

• Partner: The entity associated with the sale.
• Sales: The sales value for each transaction.
• Product: The product sold.
• Category: The category the product belongs to.

You would implement the following DAX formula to summarize sales by partner:

SalesSummaryByPartner = 
SUMMARIZE(
    Transactions,
    Transactions[Partner],
    "Total Sales", SUM(Transactions[Sales])
)

Result Interpretation

The output of the formula will yield a table displaying each unique partner alongside the total sales amount attributed to them.
