The ASR procedure, (payment authorization with reference number), enables you to send notifications, for example, settlements, to your customers with a preprinted payment authorization. Amounts paid using such authorizations are debited to your account at the Swiss Postfinance. The Postfinance regularly informs you via data media about the most recent debits.

The ASR procedure is carried out using an ASR customer number (subscriber number) assigned by the Postfinance, which is printed on the preprinted payment authorization. This procedure is only used in Switzerland and is based on an account at the Postfinance.

The ASR procedure is supported by the payment program as standard and a corresponding payment method (in the country and the company code) must be defined in the system. The authorization is printed using the International Payment Media - Check (with Check Administration) program, RFFOUS_C. The Standard System contains the SAPscript form F110_CH_ASR.

You can define the number range for your ASR form lots in the Implementation Guide under Check Management, Define Number Ranges for Checks. You can also define void reasons for checks here.

The debit notifications for the ASR procedure are returned by the Postfinance in the same way as POR credit notifications. For further processing, use the batch input report RFESR000 (see the program documentation for RFESR000).
