In the Infor M3 Accounts Payable (AP) module, a Payment Proposal is the standard procedure for generating a list of supplier invoices selected for payment. This function, typically executed in 'Supplier Payment. Propose' (APS130), allows users to define criteria such as due dates, payment methods, and currency to create a preliminary list of invoices. This proposal can then be reviewed, edited, and confirmed before the final payment documents and bank files are created. It is the foundational step in the automated supplier payment process.

A. Cost account entry: This is the accounting transaction that records an expense when a supplier invoice is initially entered, not the process of selecting invoices for payment.

C. Journal voucher entry: This is a manual general ledger entry and is not the standard, automated process used to create a consolidated list of supplier invoices for a payment run.

D. Invoice proposal: This term is typically associated with the Accounts Receivable (AR) process for creating customer invoices, not the Accounts Payable (AP) process for paying suppliers.

1. Infor M3 Finance Management User Guide for Accounts Payable: The guide details the supplier payment workflow. It explicitly states that the process begins with creating a payment proposal using 'Supplier Payment. Propose' (APS130). This function is described as the tool to "select the invoices to be paid." (Refer to sections covering the APS130 function and the overall Supplier Payment Process Flow).
