Hi Matt
For MIGO - ensure you have Launch SAP GUI checked. I will often get that message if it's not for a tcode that needs it. This is an SAP "enjoy" tcode, and most of the time it's needed.
Also go to the expert tab in the mapper and enable extended logging, if it's available. It usually provides all of the messages, including warnings and postings.
And as Gurpreet suggested, running in debug mode may help you.
Hope that helps,
Sigrid
