Transaction sources identify the source of external transactions that you import into Oracle Projects. The transaction source determines how Oracle Projects imports the transactions.

Oracle Projects provides a set of predefined transaction sources that you use to import transactions from other Oracle Applications. For example, the following processes in Oracle Projects use predefined transaction sources to import expenditures:

• PRC: Interface Supplier Costs: Uses the predefined transaction sources for supplier costs to import transactions from Oracle Purchasing and Oracle Payables.
• PRC: Interface Expense Reports from Payables: Uses the predefined transaction source Oracle Payables Expense Reports to import expense reports from Oracle Payables.
• PRC: Transaction Import: Uses predefined transaction sources to import transactions from other Oracle Applications such as Oracle Inventory, Oracle Project Manufacturing, Oracle Time and Labor, and Oracle Labor Distribution.

In addition, Oracle Projects uses predefined transaction sources to import project allocations and capitalized interest transactions that it generates internally.

You can define additional transaction sources to import transactions from non-Oracle applications. For example, you can define the transaction source Payroll to identify expenditure items imported from an external payroll system. You control the Transaction Import processing by the options that you select for each transaction source.
