The Configurable Account Analysis (CAA) doesn't support lease accounting and intercompany subledgers. It can be selected in the configuration wizard however confirmed with support that these are not built in yet.
Lease Accounting, Intercompany subledger specific features are not supported in FDI at present and hence cannot be extended to Configurable Account Analysis (CAA).
CAA by design supports sub ledger transaction details only for the functional areas enabled in FDI data pipeline. For other journal sources selected in CAA template, journal details and sub-ledger accounting specific information is supported.
Lease Accounting and Inter-company feature addition would be reviewed for future roadmap.
