The office still issues cash receipts from Access (EFE MENU -> EFE). This is that form: cliente, fecha, monto + moneda, concepto, elaboró (the logged-in user), fecha de depósito, and a folio that continues the legacy book. - cash_receipts, folio unique. Next folio = one past the highest of the platform's receipts and the imported utilities EFECTIVO journal, so after the cutover import it lands on the office's next number (13935 on prod today). A typed folio the legacy book already used is refused. - Issuing a receipt posts its credit in the same database transaction, as legacy posted to DATOS2: reference C<folio>, CASH DEPOSIT, pseudo check CASH<MMDD><P|D>. Dollars with a rate credit a pesos ledger (1,500 USD at 16.80 -> 25,200 MXN, as C13830 did). Voiding that row voids the receipt. - /efectivo: issue, search, record the deposit date; /efectivo/<folio> prints the receipt. - Reporte de efectivo now lists platform receipts by receipt, not by check, so each is counted once.
