If you followed the manual step by step up to this point, you have laid down the requirements to now configure the system activity inside the process. To do so you need to implement a process with the process table fields for all output parameters:
•returnCode (Integer)
•errorMessage (Text)
•targetFile (Text)
•numberOfRows (Text)
Additionally a subtable, subtable view, starting step and a form is required, into which the subtable view can be loaded and edited. As a subsequent step you have to define the system activity and configure the function CSV export so the subtable, input and output parameters are chosen correctly.
