Workflow Step3 : Create a method.

Next a method must be created without using any function module template. When creating the method ensure that the method call is synchronous – this means that the method doesn’t require a terminating event.

A method can be synchronous or asynchronous. Synchronous Method
Method that, for the duration of its execution, assumes the process control and, after its execution, reports to the calling component (work item manager, in this case).
Synchronous methods can return the following data, if defined: Return parameters, one result and Exceptions.

Terminating events can also be defined for a single-step task described with a synchronous method. At runtime, the relevant work item is then terminated either when the synchronous method is successfully executed or when one of the defined terminating events occurs.

Asynchronous Method
Method that, after its execution, does not report directly to the calling component (work item manager, in this case).
Asynchronous object methods do not return results, parameters or exceptions.
At least one terminating event must be defined for a single-step task described with an asynchronous object method.
At runtime, the relevant work item is only terminated if one of the defined terminating events occurs.

Next set the status of this object type component to implemented. The methods are not implemented unless you once open their program. Select the method and open its program. It gives a message “Do you want to generate a template automatically for the missing section”. Click “Yes”. Inside the program insert the code “CALL TRANSACTION ‘FB03’. Display Financial Document.
