Document Structure 

A document consists of a document header and at least two line items.

Information which applies to the entire document, such as the document date and number, is specified in the document header. It also contains controlling information such as the document type.

The line item only contains information which is specific to that line item. It always has an amount and one account number. It may also contain other specifications, such as the terms of payment, a cost center, or an explanatory text, depending on the transaction you are posting.

The system also uses special kinds of documents such as sample or recurring entry documents in addition to the accounting document described above. For more information, see Posting with Sample Documents and Recurring Entries.
