Multiperiod accounting doesn't post the journals to GL

Dear all

We have been using Oracle EBS for many years and the Multiperiod accounting will post the journal to GL for those deferred invoices once the period is opened.

e.g one invoice have two months GL date, one is May-10 and another one is Jun-20.

When user run Create Accounting in may, it will post the journal for May-20 and imported the journal for Jun-20 as unposted.

When May-20 is closed, Jun-20 is opened, the Jun-20 journal will be post after user run the Multiperiod accounting.

However since Apr-20, the Multiperiod accounting doesn't post the journal which is unposted status.
