Info

If we do not need the method in our class, then we need only to carry out a “dummy” implementation (without further coding) to avoid program errors when the system calls the method. There is an implementation example in the CL_SWF_FORMABSENC demo class. 19. BI_OBJECT~DEFAULT_ATTRIBUTE_VALUE Method: The BI_OBJECT~DEFAULT_ATTRIBUTE_VALUE method returns the display name of the object. Features: We can display references to process objects or process step objects at different positions within the SAP Web Flow Engine (for example, in Business Workplace and in Workflow Log). The object key is normally displayed here. If, for example, we want to display a descriptive text instead, the BI_OBJECT~DEFAULT_ATTRIBUTE_VALUE method has to return the corresponding value. If the method does not contain implementation or does not return a value, the object key is displayed. If we do not need the method in our class, then we need only to carry out a “dummy” implementation (without further coding) to avoid program errors when the system calls the method. There is an implementation example in the CL_SWF_FORMABSENC demo class.
20. BI_OBJECT~EXECUTE_DEFAULT_METHOD Method: The BI_OBJECT~EXECUTE_DEFAULT_METHOD method is the standard method for the object. This method is executed when, for example, we call the object in Business Workplace. Features: We can display process objects or process step objects at different positions within the SAP Web Flow Engine (for example, in Business Workplace and in Workflow Log). The SAP Web Flow Engine calls the BI_OBJECT~EXECUTE_DEFAULT_METHOD method. If we do not need the method in our class, then we need only to carry out a “dummy” implementation (without further coding) to avoid program errors when the system calls the method. There is an implementation example in the CL_SWF_FORMABSENC demo class.
