Functionality

Class used to manage a parallel execution.

This class is part of the parallelization framework, which enables you to execute reports in parallel mode. SAP delivers two classes for this framework:

• This class (CL_HR99B_PARALLEL): manages a complete parallel execution. You cannot extend this class.

• CL_HR99B_HRF_PARALLEL_JOBS:manages a parallel execution step, by creating and splitting the parallel jobs. You can extend this class according to your needs.

Note

Only SAP can enable a standardreport to be executed in parallel mode.

Methods

• CONSTRUCTOR

Reads customizing data in table T799BHRFPL using the parameters MOLGA and report name, and refreshes the selection screen data of the current report.

• AT_PBO

Sets the parallel selection screen according to the amount/type of data retrieved from T799HRFPL table.

• AT_PAI

Stores the parameters from selection screen into the AT_PARAMETERS table and stores step and job intotwo separated parameters. Also searches for a lock statement in the customizing tables that may lead to inconsistencies during parallel execution and prevents report from running.

• REQUEST_APPROVED

Prepares and calls the parallel execution by creating the parallel class and calling the RUN_PARALLEL method of this class. This method is called only by the main task at each parallel step initialization.

• END_PARALLEL_STEP

Finishes a parallel execution by saving the data into the shared memory and, if it is the main task, calls the collect method to retrieve all results.

• WRITE_TO_SHARED_MEMORY

Saves the results into the shared area, by calling the SAVE_DATA_TO_SHARED_AREA method.
