A concurrent program is an executable file that runs simultaneously with other concurrent programs and with online operations, fully utilizing your hardware capacity. Typically, a concurrent program is a long-running, data-intensive task, such as posting a journal or generating a report.

Standard Request Submission (SRS) is an Oracle E-Business Suite feature that allows you to select and run your concurrent programs from a single, standard form (Submit Request) or window (Schedule Request). Requests to run concurrent programs are called concurrent requests.

There are two main ways to group concurrent programs. Request sets are defined to run several concurrent program in a single request. Request groups are used to control access to concurrent programs via responsibilities. Both request sets and request groups are discussed in later sections
