Retrieve a single Oracle Fusion Payables invoice: header, amounts, validation/approval/payment status, matched purchase orders, and lines. Identify the invoice by invoiceId, or by invoiceNumber plus supplierName/supplierNumber/businessUnit when the number alone is ambiguous. Use this first to establish the facts of an invoice, then call get_invoice_holds, get_accounting_period_status, or get_budgetary_control_impacts for the reason it is stuck.

List the holds on an Oracle Fusion Payables invoice and explain each one: what the hold code means, which team owns the fix, whether revalidation can release it, and the steps that clear it. Returns prioritised recommended actions and flags whether payment or accounting is blocked. Use after get_invoice when an invoice is not paying or not accounting.

Report Oracle Fusion accounting period status for Payables (AP) and General Ledger (GL): Open, Closed, Permanently Closed, Never Opened, or Future Enterable. Query by period name, or by accountingDate to resolve the period that contains an invoice's accounting date. Use this when an invoice will not account, when an accounting date is rejected, or before asking for a period to be reopened. If a period status cannot be read it is reported as unavailable with the reason; a status is never assumed.

Explain the budgetary control impact on an Oracle Fusion Payables invoice: the funds check / funds reservation status, which control budgets are involved, and which lines and distributions failed and why. Use when an invoice carries an Insufficient Funds or Funds Check Failure hold, or before promising a payment date on a budget-controlled invoice. Important: this tool never estimates or derives funds balances. Budget and funds-available figures are reported only when Oracle Budgetary Control returns them; otherwise they are null with the reason they are unavailable and guidance on where to obtain them.
