Prenotification 
This process is only available in the USA. If you want to pay an employee by bank transfer, you can check the employee's bank details before the first payment by making a test transfer with the amount zero. If you use the test transfer, the preliminary program DME checks, during the Wage and Salary Payments by Bank Transfer with Payment Advice Printing process, if a test transfer was made to check the bank details. In the following situations it changes the bank transfer into a check payment:
You have still not created the DME file for the test transfer.
The test transfer revealed that the bank details are invalid.
The test transfer was made less than 10 days ago.
You have stored the bank details for the bank transfer in the Bank Details infotype (0009) and, if necessary, in the External Bank Transfers (0011) infotype.
You have set up the creation of short-term documents for the Bank Details (0009) and External Bank Transfers (0011) infotypes (in Customizing for Payroll under Payroll: USA ® Electronic Funds Transfer (EFT) ® Prenotification ® Set up Prenotification).
...
You create, or change, the Bank Details (0009) or External Bank Transfers (0011) infotype for one or several employees. You enter bank details when doing this.
The system creates (dependent on your Customizing settings) short-term documents for these infotypes.
You start the Prenotification program (Report RPCDTEU0) at the appropriate time.
The system reads the short-term documents for the specified time, and creates entries in the Prenotification: New Bank Data from Master Records table (PNBK) for the bank details that are to be tested.
You start the Prenotification: Creation of the Prenotification File program(Report RFPNFC00).
The system creates a prenotifications file in ACH format.
You provide your house bank with the prenotifications file.
Your house bank checks the bank details and reports any possible errors, so that the employee's master data can be corrected.
