ABAP OO-Task Scheduler

ABAP utility to do "CALL METHOD ... IN UPDATE TASK / STARTING NEW TASK / VIA JOB"

Usage

Context: you have implemented your business logic inside a class ZCL_MY_CLASS used with an instance o_my_object and you'd like to refactor your methods in such a way you can start new task / update task / background job without creating Function Modules or Report, using only oo-artifacts.

• Implement interface ZTBOX_IF_PROCESSER in your class ZCL_MY_CLASS
• Create an object of ZTBOX_CL_PROCESSER passing an instance of your class

DATA(processer) = NEW ztbox_cl_processer( o_my_object ).

• To execute a method in update task: call method UPDATE_TASK passing the name of the method

processer->update_task( 'GET_DATA_AFTER_COMMIT' ).

• To execute a method in a separate task: call method NEW_TASK passing the name of the method

processer->new_task( 'PROCESS_DATA_NEW_SESSION' ).

• To execute a method as a background job: call method NEW_JOB passing the name of the method

processer->new_job( 'PROCESS_DATA_BACKGROUND' ).

• To perform a sequence of task-methods in such a way each task is executed only after the previous one has ended: call method PERFORM_TASKS passing the name of the methods forming the sequence (order is relevant)

processer->perform_tasks( VALUE #(
  ( 'CREATE_PURCHASE_ORDER' )
  ( 'CREATE_GOODS_RECEIPT' )
  ( 'CREATE_MIRO_INVOICE' ) ) ).

Each of these methods from ZCL_MY_CLASS must not have mandatory parameters. Any initial parameters should be set as instance attributes, such as with o_my_object->set_data( ... )..

If, e.g., CREATE_PURCHASE_ORDER method sets instance attribute _purchase_ord_number, its value is accessible from method CREATE_GOODS_RECEIPT when the sequence of tasks of the last example is performed.
