IsValid

Returns TRUE if the specified element validates successfuly.

Syntax

IsValid ( member | tuple | set | layer | property )

Example

Example 1

The following example shows how IsValid can be used to check whether a given property value is valid. It returns all Product dimension members that have an Ounces attribute value of 12.

SELECT
Filter([Product].members, 
       IsValid([Product].CurrentMember.Ounces) 
           AND
           [Product].CurrentMember.Ounces = 12)
ON COLUMNS 
FROM Sample.Basic

The expression IsValid([Product].currentmember.Ounces) returns TRUE for only those members in the Product dimension that have a valid property value for [Ounces]. This eliminates ancestral members such as [Product] and [Colas] that do not have the [Ounces] property defined because they are not level-0 members of the Product dimension.

The second part of the AND condition in the filter selects only those members with a value of 12 for [Ounces].

This query returns the following grid:

Example 2

IsValid([Jan].FirstChild) 

returns FALSE, because [Jan] is a level-0 member, therefore it does not have any children.
