Returns the specified member and all siblings of that member. This member set function can be used as a parameter of another function, where that parameter is a list of members.
Any valid single member name or member combination, or a function that returns a single member or member combination.
Essbase sorts the generated list of members in ascending order. Using Sample Basic as an example, if you specify 200-30 for mbrName, Essbase returns 200-10, 200-20, 200-30, 200-40 (in that order). This order is important to consider when you use the @ISIBLINGS member set function with certain forecasting and statistical functions.
In the Sample Basic database:
returns California, Oregon, Washington, Utah, and Nevada (in that order), because these members are siblings of California.
returns Qtr1, Qtr2, Qtr3, and Qtr4 (in that order), because these members are siblings of Qtr2.
