Suppose the Dimension Member name is "Entity", it has to be populated as "ENTITY" and we should also have another value as "ENTITY2". All the Entity nodes should be populated for these two members.
eg:
Entity value are : E100, E200 and E300
Extract should be:
ENTITY E100
ENTITY E200
ENTITY E300
ENTITY2 E100
ENTITY2 E200
ENTITY2 E300
