Shared Members in EssBase

Shared Members:

A shared member is used to create alternate hierarchies. The data for shared members come from the original member. There is no storage space reserved for the shared member. The below rules must be followed for shared members.

  1. A shared member name must be same as the original member.
  2. The shared member must come after the original member.
  3. The shared member and the original member must belong to the same dimension.
  4. We can create any number of shared members in an outline.
  5. The shared member cannot have formula, UDA, Attribute attached to it.
  6. The shared member can have an alias.
  7. The shared member cannot have child members.

In this example, Soda is parent member and coke, pepsi are child members. Coke has two child members, coke-1L and coke-2L. Pepsi has two child members, Pepsi-1L, Pepsi-2L.

In the report, we want to get the total for coke and also, we want to get the total for Pepsi. In another report, we want to get the total for 1L products and total for 2L products. Essbase doesn’t allow duplicate records. To get 1L totals, create 1L parent and add coke-1L and Pepsi-1L as shared members. Create 2L parent in product dimension and add Coke-2L and Pepsi-2L as shared members.

 

Note:

Shared   members increase the size of the outline.

To create shared members using Rules files, use Duplicate Generation reference or parent

Child reference member.

 

To create the above outline , using parent child reference method, use the source as mentioned

this method automatically creates ~ symbol on shared member parent .(EX: on 1L and 2L )

 

implied sharing:-

  • When a parent has only one child , analytic services doesn’t need to calculate the parent member . its simply refers the value from it’s child .

 

In this example , quantity parents has only one child and it need not to get calculated from .

Child, instead it simply refers the value from opening in 0 field . there is no storage

Space reserved for “quantity ” member.

  • When a parents has more than one child , but other one child has consolidation symbol + and other child members has ~ operator , then analytic services doesn’t need to calculate the parent member its simply refers the value from the child i.e having +operator .

In this example quantity parent has three child members but only opening inventory has + operator and the remaining member has ~ operator. Quantity simply referable from opening inventory field . there is no storage space reserved for “quantity” member .
