The posting programs update the Open Billing Detail for projects with transaction-based billing formulas.

The Calculate Standard Bills screen copies allowable transactions in this table into Billing Edit Detail. Transactions include costs, units, and hours. The link between the two tables is the "Billing Transaction Key," a multi-field key that uniquely identifies individual transactions.

Transactions can be partially billed. In order to be able to partially bill transactions for a given project, you must select the Allow Transactions To Be Partially Billed check box on the Setup Information tab of the Manage Project Billing Information screen. If you do not select this check box, transactions must be billed entirely, or not at all. In the calculation of allowable amounts, transactions that cannot be partially billed are disallowed entirely once a ceiling is reached.
