In this step, you stipulate that a check digit is allocated when customer or vendor master records are created. The system then assumes that the last digit in the customer/vendor number is the check digit.
In internal number assignment, the system allocates the check digit automatically; in external number assignment, the system automatically interprets the last digit as the check digit.
Requirements
If you want to work with check digits in internal number assignment, the number range interval for customer/vendor master records may only have nine characters. The system automatically inserts the check digit as the last character.
Activities
If you want to work with internal number assignment, first verify that the number range interval for the customer/vendor master record has been defined with only nine digits.
Enter the number range object CUSTOMER for customer master records.
Enter the number range object VENDOR for vendor master records.
The following function is only available for the client German Local Authorities: Enter the number range object PSOOB for the object master records.
Further notes
You can also activate the check digit procedure using the enhancement Master Data Subledger Accounts (SAPLF0KB) (Component Active Check Digit Procedure: Return code equals zero (EXIT_SAPLF0KB_001) package FMKW). If check digits are being used, the MODULO11 procedure is used. If you want to use another procedure, use the appropriate component Return Number Including Check Digit (EXIT_SAPLF0KB_002) of enhancement SAPLF0KB.
