Hello Guys, I have solved my problem, MIGO Transaction can't debug the pinting directly, you can debug your smarform of MIGO in MB90 transaction.
In ouput type you need pass your ouput type, in my case was: WE01 and Processing Mode:2
and you need pass material document number and Material Doc year after this you can see your documents:
Select your document and press run button, but make sure you have a breakpoint in the initialization code of smartform previously
