In the current version, you can enable/disable incremental load in the Transfer task. If you like to schedule an incremental load on weekdays and a full load in the weekends for example. You need to recreate the data transfer task. And when you need to add tables to the transfer task, you need to do it twice (for incremental and full data transfer).
Unfortunately it is not possible to copy/clone ODX tasks, so it can be a lot of work to recreate a transfer task.
It would be way easier if the incremental enable/disable option is moved to jobs. This makes it possible to create an incremental and a full load job. Both jobs are connected to the ODX same transfer task.
