System status for IDOC creation and processing for production orders

All

I am creating IDOCs for production orders to send requirements to an external WM system for kitting execution.

I need to know whether there are any system statuses to notify me when an IDOC has been created,failed and processed. If not, how do I go about creating user defined statuses for these statuses.

Second question, which idocs should I use to confirm, teco and cancel the production orders from an external system?

Thanks
