If you are using a version of Dynamics AX prior to AX2012 R3 then the task record is a handy tool for documenting a flow in application screens either for documentation, training or support purposes. If you are using AX2012R2 and prior versions back to AX4.0 the task record will look similar to what is covered in this overview.
The task recorder was updated for use with Lifecycle services after AX2012 R2 was release and a download and included in R3 with new features that aren’t covered in this video.
