The posting function transfers the data to Financial Accounting.

Each financial transaction is based on certain transaction data (such as nominal amounts, interest rates). The flows relating to a financial transaction are generated from this transaction data. These flows are used to determine the data that is required for posting, such as document types, balance sheet accounts or income statement accounts and the posting keys. This data and the flows to be posted are transferred to the FI interface that generates the relevant postings and documents using the corresponding functions. The document principle is used throughout the entire SAP System. In other words, postings are always saved as documents. The document is kept as a unit in the system until it is archived.

The posting responsibility lies in Accounting, yet the account assignment rules for the posting types are fixed and monitored in Corporate Finance Management. This reporting structure ensures a division of functions that does not burden the Accounting area with posting tasks that would be inefficient. This also helps to avoid posting errors and loss of information.

Before you transfer the flows to FI, you determine the relevant posting specifications using the flexible account determination. The posting specifications identify the accounts used in the posting run. Account determination is based on a general concept with replacement rules and masking. You set up the account determination only once during implementation. This ensures a standard procedure and minimizes the number of input fields.
