Partial Replica of Primary Ledger

Hi,

We are in a project to re-implement and consolidate three dfferent 11i instances into one 12.1.3 single global instance.My client has a unique requirement. To deal with very big customers, they have different incorporated companies in the Americas and each company is represented by a balancing sgment value. The big customers have different GL calendars to follow and need to access their financial transactions with my client as recorded in my client's book. Currently, the client has one primary ledger for all the BSVs (including the ones created for each big customer) and one primary ledger for each such big customer calling
