How to book topside journal entry to load opening balance to a new parent in FCCS

Summary:

We are changing our entity structure and introducing a new sub parent. We observed the period activity is rolling up correctly to the sub parent but opening balance is not rolling up. We tried to copy the prior period closing balance of old parent but only total input and adjust data is getting copied, Total elimination is not getting copied. Addition we cannot copy to CTA account.

Planning to book a top side journal entry to load the opening balance to a adjustment entity under new parent.

New understanding on how this topside journal entry can be prepared. We are trying to use closing balance of prior period of earlier parent as periodic movement.
