Siblings

Returns the siblings of the input member, optionally based on selection options.

Syntax

Siblings ( member[, selection [,include_or_exclude]] )

member.Siblings

Parameter	Description
member	The member for which siblings are returned.
selection	Optional. This option can be one of the following: LEFT—Selects the siblings to the left of the input member RIGHT—Selects the siblings to the right of the input member ALL—Selects all the siblings of the input member If no selection is made, the default is ALL.
include_or_exclude	Optional. This option can be one of the following: INCLUDEMEMBER—Includes the input member in the siblings list EXCLUDEMEMBER—Excludes the input member from the siblings list If neither is specified, the default is to include the input member.

Parameter

Description

member

The member for which siblings are returned.

selection

Optional. This option can be one of the following:

LEFT—Selects the siblings to the left of the input member
RIGHT—Selects the siblings to the right of the input member
ALL—Selects all the siblings of the input member

If no selection is made, the default is ALL.

include_or_exclude

Optional. This option can be one of the following:

INCLUDEMEMBER—Includes the input member in the siblings list
EXCLUDEMEMBER—Excludes the input member from the siblings list

If neither is specified, the default is to include the input member.

Notes

If the input member is the top level of the dimension, this function returns a set containing the input member.
In aggregate storage databases, in multiple-hierarchy-enabled dimensions, if the input member is a top-level member of a hierarchy, the output is members across hierarchies that are top-level members of hierarchies.
This function is the same as Children(member.parent).
The member. Siblings syntax returns the same set as Siblings(member), Siblings(member, ALL), or Siblings(member, ALL, INCLUDEMEMBER).

Example

Example 1

Siblings(Year) returns {Year}.

The following query

SELECT
CrossJoin (
         Union (
            Siblings ([Old Fashioned]),
            {([Root Beer]), ([Cream Soda])}
         ),
         {(Budget), ([Variance])}
      )
ON COLUMNS
from Sample.Basic

returns the grid:

Old Fashioned		Diet Root Beer		Sarsaparilla		Birch Beer		Root Beer		Cream Soda
Budget	Variance	Budget	Variance	Budget	Variance	Budget	Variance	Budget	Variance	Budget	Variance
11640	-4439	14730	-2705	5050	-414	4530	-438	35950	-7996	29360	-3561

Example 2

The following examples are based on a Years – Quarters – Months Time hierarchy.

Siblings([Feb 2000], LEFT, INCLUDEMEMBER)

Returns {[Jan 2000], [Feb 2000]}.

Siblings([Feb 2000], RIGHT, EXCLUDEMEMBER)

Returns {[Mar 2000]}.

Siblings([Mar 2000], LEFT)

Returns {[Jan 2000], [Feb 2000], [Mar 2000]}.

Siblings([May 2000], RIGHT)

Returns {[May 2000], [Jun 2000]}.

Siblings([Mar 2000])

[Mar 2000].Siblings

Returns {[Jan 2000], [Feb 2000], [Mar 2000]}.
