POS Interface - Inbound: Financial Transactions 
Use
Financial transactions are events that take place at the point of sale involving cash but no goods movements, for example:
The financial transactions handled in the store are modeled in SAP Retail in Financial Accounting.
Features
The various financial transactions carried out in the POS system are identified in SAP Retail by transaction types. The transaction codes in the POS system can be converted automatically in SAP Retail to the required transaction types. The transaction type allows the relevant account to be determined. This is why the POS system only has to transfer the most basic information on financial transactions to SAP Retail. In most cases it is sufficient to transfer the transaction type and the amount. Additional information, such as an assignment number, used to assign open items to each other, can be transferred if required.
