We had a case where D365 FO allowed to create and post general journals with voucher number starting with a parenthesis (or brackets) such as (O)-123456.
Although the D365 FO allows you to post voucher with open and close bracket special characters it is currently not supporting the parenthesis while doing voucher inquiry and users will be unable to perform settlement.
Microsoft D365 FO might come out with a complete fix for this issue with their future updates, but currently this will be an issue to use special characters such as "(" or ")"
While trying to search for the voucher you will face the below error:
"Query extended range failure: Syntax error near 3."
