Initiate Sales Order IDOC creation

I configured Message Control for sending IDOC on Sales Orders create / change in VA01 / VA02. It works.

IDOC type: ORDERS05

FM: IDOC_OUTPUT_ORDRSP

2 questions:

1) How can i send the same IDOC from my program whenever i want. In other words - initiate Sales Order IDOC creation.

2) Will be IDOC sent when Sales Order status is changed:

- Delivery in VL01N

- Sales Order is canceled
