The service type with the Business service symbol in the EPC has exactly one software service type, which encompasses multiple software service operation types.
The function that is linked to the service type in the EPC is transformed into a task in the BPMN diagram. The Task type attribute is automatically set to the value Service.
Since the service type is realized using multiple software service operations, the correct software service operation to be linked to the task in the BPMN diagram cannot be determined automatically during the transformation.
The task is therefore placed in the system lane. You must manually create the missing lanes and link them to the corresponding software service operations in the BPMN diagram.
