Union (PEL)

This function returns a MemberSet that is generated by the union of two MemberSets.



  • MemberSet_Expression1
    A valid PerformancePoint Expression Language (PEL) expression that returns a MemberSet
  • MemberSet_Expression2
    A valid PEL expression that returns a MemberSet

Return value

The Union function returns the union of two specified MemberSets.


The PEL compiler can generate SQL code for this function when the function is part of an absolute reference. The compiler cannot generate SQL code when the function is part of a relative reference.

PEL cannot be used to reference user-created member views in non-time dimensions. To write a business rule that references a member view in a non-time dimension, use a native Multidimensional Expressions (MDX) implementation.
