The shared member property defines a shared data relationship explicitly. Some members are shared even if you do not explicitly set them as shared. These members are implied shared members.
Essbase assumes (or implies) a shared member relationship in the following situations:
A parent has only one child. In this situation, the parent and the child contain the same data. Essbase ignores the consolidation property on the child and stores the data only once—thus the parent has an implied shared relationship with the child. In the following example, the parent 500 has only one child, 500-10, so the parent shares the value of that child:
500 (+) 500-10 (+)
A parent has only one child that consolidates to the parent. If the parent has four children, but three are marked as no consolidation, the parent and child that consolidates contain the same data. Essbase ignores the consolidation property on the child and stores the data only once—thus the parent has an implied shared relationship with the child. In the following example, the parent 500 has only one child, 500‑10, that rolls up to it. The other children are marked as No Consolidate(~), so the parent implicitly shares the value of 500‑10.
500 (+) 500-10 (+) 500-20 (~) 500-30 (~)
If you do not want a member to be shared implicitly, mark the parent as Never Share so that the data is duplicated instead. See Understanding Shared Members for an explanation of how shared members work.
