Creating Method to Execute Work Items Together (BOR) 
The Workflow Inbox gives you the option to mark several work items and execute them together. Here you only execute the first work item. All other work items are executed by the workflow system in the same way as the first work item. For example, you can approve several leave requests at the same time whereby you only approve the first one and those remaining are selected by the workflow system.
For you to be able to use this function in the Business Workplace, the work items selected must fulfill the following prerequisites:
The method with this task must be executable synchronously.
The method must have exactly one export parameter or one result parameter which contains the result of the first method execution.
You must insert the sections of the example program that are colored and highlighted by the NEW comment in an existing implementation program of a method, so that work items for this method can be executed together.
Work items that refer to the Approve method of FORMABSENC object type can be executed together. The PROC_STATE parameter is marked as the result parameter.
