One time accounts
Accounting with SAP R/3
Account on which the transaction figures for a group of customers/vendors with whom you only conduct business once or rarely are recorded.
One-time accounts require a special master record.
Certain customer/vendor data such as address and bank details, is not entered in the master record but in the document itself.
