Period Close Process for Reporting ledger in Receivables

Hello All,

Need to understand the period close process for reporting ledger in R12. Whether the unposted items report needs to be run before finally closing reporting ledger? OR Whether the reporting ledger will get automatically closed on finally closing the primary ledger associated with Reporting ledger without running the unposted items report.

Please provide any documentation/link to documentation on the above context.

Regards,

Raman
