Journal reversal - Accounting date if frozen

Summary

Journal reversal - Accounting date on reversed journal is frozen

Content

Hi GL Guru's 

As a routine process Accrual journals are reversed -- User tried to update accounting date to end of the month -- surprisingly the accounting date is frozen on Reversed journal. 

To understand better -- deleted reversed journal 

Reverse option is enabled on original journal --> reprocessed reversal --> on new journal Accounting Date is frozen. 

For majority journals we are able to access Accounting date and update as needed ...... for few Reversed journals -- Accounting date field is frozen....... 

Any suggestions about which configuration or activity causing this issue.
