DETAILROWS DAX Function (Table manipulation) Context Transition
Returns the table data corresponding to the DetailRows expression defined on the specified Measure. If a DetailRows expression is not defined then the entire table to which the Measure belongs is returned.
Syntax
| Parameter | Attributes | Description |
|---|---|---|
| Measure |
A Measure reference whose DetailRows expression is to be evaluated. |
Return values
Remarks
IMPORTANT : DETAILROWS should perform a context transition, but in SSAS 2017 it does not do that. The behavior by design is to perform a context transition, and this should be fixed in upcoming hotfix or service packs. As a workaround, if called in a row context, it should be wrapped in a CALCULATETABLE statement. Do not use in a row context if the intended behavior should not execute the context transition – assign the result of DETAILROWS in a variable before the iterator in that case.
Examples
Consider the following Detail Rows Expression in the Sales Amount measure:
SELECTCOLUMNS (
Sales,
"Order Number", Sales[Order Number],
"Order Line Number", Sales[Order Line Number],
"Customer", RELATED ( Customer[Name] ),
"Product", RELATED ( 'Product'[Product Name] ),
"Quantity", Sales[Quantity],
"Line Amount", Sales[Quantity] * Sales[Net Price]
)
DETAILSROWS invokes the Detail Rows Expression for the corresponding measure in the same filter context.

EVALUATE
CALCULATETABLE (
DETAILROWS ( [Sales Amount] ),
'Date'[Date] = DATE ( 2007, 9, 19 ),
Customer[Customer Type] = "Person"
)
