When can you change the posting date of a journal entry?

The posting date of a journal entry in SAP Business One can only be changed if the entry has not yet been posted. This is because the posting date designates the date on which the journal entry will affect the accounts within the general ledger. Once an entry has been posted, it becomes part of the financial records, and changing the posting date could lead to discrepancies in financial reporting and account balances. Therefore, the system restricts modifications to the posting date for any entries that have already been finalized through the posting process. This ensures the integrity and accuracy of the financial data maintained in the system. Other options reflect scenarios that are not permissible, emphasizing that changes can only be made prior to the posting action.
