Parallelization Framework for ABAP Systems
Parallelization Framework for ABAP Systems
ABAP Parallelization Services are designed to be called from code in order to run a function unit / report / method with multiple parameter combinations in parallel.
As I could not find anything from SAP as versatile, easy to use and available on any SAP system able to run ABAP I started this project. I know many companies (customers, addon vendors and consulting companies) do have their own implementation. Most of the time these had been started to solve a certain purpose and have ben generalized after.
This project tries to suit those with a generic approach in order to give every company the possibility to easily run code in parallel without a big barrier to climb before.
Executables supported: function unit, report, method
Parallelization technique: dialog task, batch task
The design has on Premise in mind. Whether this could work in BTP has not yet been discussed.

The caller must supply the following information:
The Application information and Configuration information are supplied via customizing tables (for reusability and easy change). The Parameter Sets must be implemented and the class doing so must be specified in the Application.
Using the max package size from the Configuration a so called Packetizer groups the Parameter Sets into Packages. Every Package is then assigned to one Task, which can be a Dialog Task or a Batch Task. A Task Starter (scheduler) then starts the Tasks regarding the max parallel settings from the Configuration and collects final states of the tasks including the results. When all Tasks are finished the caller can then retrieve the results if needed to further process them.
ABAPgit currently does not support SM62-event to be stored in git. Therefor the customer event ZAPS_JOB_START must be created manually using transaction SM62.
This is used for batch jobs to be started after creation.
The development package ZAPS_DEMO contains demo reports that show how to use the ABAP Parallelization Services in different situations.
| Demo Report Name | demoed functionality |
|---|---|
| zaps_demo_execute_funcunit | Execute a function unit with batch jobs and receive results |
| zaps_demo_execute_func_dia | Execute a function unit with aRFC and receive results |
| zaps_demo_execute_report | Execute a report with batch jobs (no results possible) |
| zaps_demo_execute_object | Execute a method with batch jobs |
The current state has never been used in real world scenarios. All demo reports work as expected and the unit test are running fine.
Ideas for stabilization and enhancement are welcome!
