B1if File2B1 Scenario Design

Hello gurus!

Trying to create a scenario package where the B1i would read from an xml or txt file and create a sales order on B1,

I am getting an error whilst on the inbound step design and I cannot complete the Channel form.

Also typing on the text boxes is disabled.

Since I do not have a complete guide of sorts in order to create this, what could this error be triggered from?

Even better, is there a guide I could use?

Thanks in advance!
