Returns a list of key column values from the rows in the specified table or slice in which the specified Ref-type column refers to this row (the row from which the REF_ROWS() expression is evaluated).
This expression answers the following question: Which rows in a data set refer to this row from a particular column?
Sample Usage
REF_ROWS("Order Details", "Order ID")
Returns a list of rows from the Order Details table whose Order ID column value matches this row's key column value, where "this row" is the row from which the REF_ROWS() expression is evaluated. This expression is functionally equivalent to each of the following expressions:
FILTER("Order Details", ([_THISROW] = [Order ID]))SELECT(Order Details[Order Details ID], ([_THISROW] = [Order ID])).
Syntax
REF_ROWS( from-dataset , ref-column )
from-dataset: Name of the table or slice (the data set) in which related rows are to be found.
ref-column: Name of a column in the data set named byfrom-datasetthat containsRef-type values.
Note that both arguments must be raw text values (quoted or unquoted) that identify an existing table or slice (from-dataset) and column (ref-column); they cannot be expressions.
Notes
If a column's app formula consists exclusively of a simple REF_ROWS() expression, a row added from the resulting list's inline view will automatically be populated with a reference back to the row of the REF_ROWS() expression, creating a child-parent relationship. The parent reference will be placed in the column named by the ref-column argument of the REF_ROWS() expression.
