Answer:
The way thing are done has gone through lot of changes as you have observed already.
In order to make use of the payment batches functionality in Release 12 under payables module, you need to perform most of the required setups from Payments Administrator or Payments module.
The payment batch is renamed as Payment process Request.
The process remains the same.
Selection of invoices, build, format and confirm.
Few reports which were used in r11 in the above processes were obsoleted and replaced with few new ones in r12.
In short please define the following in order to make multiple payments in release 12.
1) Bank Account
2) Payment Format
3) Payment Method
4) XML template
5) Payment Process Profile
The following are the steps for Paying Invoices in Payment Batches:
1. Initiate the payment batch by entering criteria for invoices you want to pay. Payables selects invoices and builds the payments; it determines which invoices will be paid on each payment document and lists this information for you on the Preliminary Payment Register.
At any time before formatting, you can optionally modify the payment batch. You can prevent payment to a supplier, prevent payment of a particular invoice, change the invoice amount, or add an invoice that Payables did not originally select.
2. Format payments to have Payables produce an output file.
3. Print checks from the output file, create electronic payments, or deliver the output file to your bank to disburse electronic payments.
4. Confirm the payment batch by recording the document numbers associated with each payment. During this step Payables updates the invoice status to paid and associates a payment number with the invoice and invoice payment. Do not send checks to suppliers before confirming the payment batch.
Payables creates a Final Payment Register which you can review to verify the completed payment batch.
After confirming the payment batch, you can review the Payment Batch Control Report to verify the accounting distributions of the invoices you paid. You can submit this report after every payment batch to compare it with actual payment information. You can also use this report to provide your organization's check signer with comprehensive information about each payment document, eliminating the need to review paper invoices. The report displays payment, supplier, invoice, and expense information.
You can check the status of a payment batch at any time during the payment batch process by checking the Status field in the Payment Batches window.
You can restart a payment batch if a concurrent process fails. You can also restart check printing if the printer malfunctions during check printing.
