Using ABAP Classes in Workflow: Within the SAP WebFlow Engine we can use ABAP classes that support the IF_WORKFLOW interface. Classes that have implemented the IF_WORKFLOW interface are recognized as workflow-enabled in the Class Builder. 13. How to create ABAP Classes that support IF_WORKFLOW interface? Go to transaction SE24 and create a customized class.
Next the pop up appears where we need to mention the detail as follows: Save it and the class is created. Now the class is to implement IF_WORKFLOW interface. For this go to the tab and declare the IF_WORKFLOW as the interface there and press Enter; two sub-interfaces appear: BI_OBJECT and BI_PERSISTENT. Save the Class.
