The data is added to the receipts database using the parser which processes the receipts. This is an optional function in addition to the system setup.

Depending on the protocol of data transfer from the POS-terminal to the POS-server, the database can be filled up:

1. using the xml_titles.txt parser;
2. using a .prl parser.

The xml_titles.txt parser specifies the rules for adding data to the receipts database if the data is transferred from the POS-terminal to the POS-server using the XML protocol. The parser contents depend on the structure of the XML data. To use the xml_titles.txt parser, the parser file should be located in the <POS PSIM program folder>\Modules\Pos folder.

If the POS-terminals connected to the POS-server have the same XML data structure, common xml_titles.txt file can be used. If the POS-terminals connected to the POS-server have different XML data structures, a separate parser should be created for each terminal. The parsers should have files of the xml_titles_N.txt form, where N is the number of the corresponding POS-terminal object.

The .prl parser specifies the rules for adding data to the receipts database if the data is transferred from the POS-terminal to the POS-server using a protocol other than XML. The parser contents depends on the POS-terminal data structure. To use a .prl parser, its file should be imported into the system.
