Creating an "Execute Together" Method

The Business Workplace provides you with the option of executing work items together. This enables you to approve or reject several leave requests at the same time, for example.

The following are prerequisites for this function:

The work items must refer to the same single-step task.

If the work items belong to a single-step task whose executable method is defined with parameters, these work items can only be executed together if the elements in the method container and the corresponding elements in the task container have the same names.

The method must be executable synchronously.

The method must have at least one import/export parameter, which contains the result of the first method execution.

The method Approve of the object type WFTS is an example of a method that can be used for the function Execute together.
