Automatic Delivery Outbound Delivery and Goods Issue Creation

Hi All,

I was doing a goods reciept for a PO. And upon saving it, an outbound delivery should be created and will also goods issue the delivery. It will be done when an output type is triggered when the PO is change. Does anyone knows where the PO is updated when using the MIGO transaction. Or can anyone suggest on how can I make it possible to trigger the ouput type in the PO when I create the GR.

Note: The Output Type/Message Type is only triggered when the document type is NB and is only set on the PO.
