To keep a thin secondary ledger, you should select the balance level as the data conversion level. This means that only the ending balances of the primary ledger are copied to the secondary ledger at the end of each period. This reduces the data volume and storage requirements of the secondary ledger, as well as the processing time and resources needed to copy the data. The balance level conversion is suitable for scenarios where the accounting methods or charts of accounts are similar between the primary and secondary ledgers, and there is no need to maintain detailed journals or subledger transactions in the secondary ledger. References: Primary Ledgers, Secondary Ledgers, and Reporting Currencies, How Journals Are Copied from Primary to Secondary Ledgers When …, GL Secondary Ledger Conversion Level Change

Balances cubes are multidimensional databases that store financial balances for interactive reporting and analysis. A balances cube is created for each unique combination of ledger and currency, and it contains dimensions such as chart of accounts segments, periods, scenarios, and other user-defined attributes. New dimensions can be added to a balances cube by using the Manage Balances Cube Dimensions task in General Ledger. Balances cubes are updated automatically when journals are posted in General Ledger, and they can also be refreshed manually by using the Refresh Balances Cube task. Balances cubes are not affected by the Translation or Revaluation processes, as these processes only update the balances tables in General Ledger. References:

According to Oracle documentation3, Oracle’s recommended method to define a chart of accounts that includes an intercompany segment when your customer plans to use segment value security rules for the Company segment is to share the same value set for the company and intercompany segments. Sharing the same value set enables you to use segment value security rules for both segments and ensures that the values in both segments are consistent. Therefore, option B is correct. Option A is incorrect because defining the intercompany segment with a default value does not enable segment value security rules for the intercompany segment. Option C is incorrect because defining the company segment and assigning both the primary balancing segment and intercompany segment labels does not enable segment value security rules for the intercompany segment. Option D is incorrect because creating two different value sets for the company and intercompany segments does not ensure that the values in both segments are consistent.
