Request sets allow you to submit several requests together using multiple execution paths. A request set is a collection of reports and/or programs that are grouped together. You can thus submit the reports and/or programs in a request set all at once using a single transaction.
Request sets support multiple execution paths. Request sets can be defined to submit requests depending on the completion statuses of previously submitted requests in the set. For example, if a certain request were to fail, a set could submit a cleanup request, rather than continuing along its normal execution path. A set could submit one request or another based on the number of lines posted by earlier requests. A single set can now execute certain groups of requests in parallel while executing other requests serially.

The completion status of a stage is computed by a PL/SQL function. The function can use information about the requests in a stage when calculating the status of the stage. For example, the Standard Stage Evaluation function uses the completion statuses of the requests in a stage to calculate the completion status of that stage. For each stage in your set, you can choose a function from the list of registered functions. You can also specify which concurrent requests in the stage will provide information to be used in the function's calculation. Most stages will use the Standard Stage Evaluation function, but other functions are available.
Any stage may use the Standard Stage Evaluation function provided by Oracle Application Object Library. This function computes the stage completion status from the completion statuses of the specified requests in the set. The Standard Stage Evaluation function will return Success if all of the requests completed with Success. The function will return Error if one or more requests completed with Error. Finally, the function will return Warning if one or more requests completed with Warning, and no requests completed with Error.
