Suggestion:
A Journal Voucher (JV) describes a transaction used for recording financial activity.
A JV must include a debit and a credit, so that it is balanced, and a description with enough detail so that when you are looking at that journal at a later date, it is clear what the journal relates to.
A journal voucher is an integral part of the audit trail, and carries (1) a serial number, (2) transaction type as ‘Gen’,(3) transaction date, (4) reversible (Y/N), (5) reference series (e.g Voucher, Receipt, Sales order, invoice, misc payable…etc) transaction amount, (6) account(s) affected for debit and credit, (7) analysis code, (8) sundry type and code e.g supplier, customer, others etc to support the invoices or receipts entry.
Journal Voucher menu exists in the Finance -> General Ledger-> JV-> Journal Voucher.
