Returns the value in result_columnName for the row that meets all criteria specified by search_columnName and search_value.
LOOKUPVALUE( <result_columnName>, <search_columnName>, <search_value>[, <search_columnName>, <search_value>]…)
|result_columnName||The name of an existing column that contains the value you want to return. The column must be named using standard DAX syntax, usually, fully qualified. It cannot be an expression.|
|search_columnName||The name of an existing column, in the same table as result_columnName or in a related table, over which the look-up is performed. The column must be named using standard DAX syntax, usually, fully qualified. It cannot be an expression.|
|search_value||A scalar expression that does not refer to any column in the same table being searched.|
The value of result_column at the row where all pairs of search_column and search_value have a match.
If there is no match that satisfies all the search values, a BLANK is returned. In other words, the function will not return a lookup value if only some of the criteria match.
If multiple rows match the search values and in all cases result_column values are identical then that value is returned. However, if result_column returns different values an error is returned.
The following example returns the SafetyStocklLevel for the bike model "Mountain-400-W Silver, 46".
=LOOKUPVALUE(Product[SafetyStockLevel], [ProductName], " Mountain-400-W Silver, 46")
