P invoices. A batch payment groups one or more invoice payments into the payment transaction reported by SAT.
Use batch payments when you need payment-method, currency, bank, operation-number, or transaction-level information. Use invoice payments when you need the amount applied to a specific deferred invoice.
Batch payments are extracted from invoice data. To retrieve them, run an invoice extraction for the entity and include payment receipt CFDIs by keeping type P invoices in the extraction options.
