To ensure data integrity, server-based consolidation structures allow only one data representation per entity, no matter how many consolidation structures share each entity.
For example, a consolidation structure called ‘West’ contains child entities ‘Accounting’ and ‘Manufacturing’. ‘Purchasing’ is a child of ‘Accounting’, but you want to create a copy to see what happens if ‘Purchasing’ rolls into ‘Manufacturing’. You can not do this on the server, because moving ‘Purchasing’ into a second consolidation structure breaks the first structure.
Use consolidation labels to create variations of consolidation runs within the server
