Method Directive Generated POs Default Comment Text

I currently have a method that automatically sets a comment text in the PO Header. It works great except when the PO is generated from Buyer Workbench, the default comment method does not get triggered.

I went through the tracing procedure to try and find what method i need to modify, but I still cannot get it to work the way I want it to.

Any ideas?

This is where a Data Directive may actually come in handy… @hkeric.wci do you have another idea?

Did you ever get this to work?
