You have to create a Processing Rule in TN, and have matching criteria , for e.g. here you can give the doc type name. Then in the action, Execute a service, that service should be present on the IS. In the service, you need to have bizdoc as the input, a doc reference of wm.tn.rec:bizdoc. The first step of the service should be convert the bizdoc/content to string using pub.string:bytesToString. YOu now have the content, you can save the doc to Hard disk using writeToFile and update status using an adapter. This is a standard/basic B2B Integration scenario which you can get if you go through TN users guide thoroughly. Please carefully follow the documentation before you proceed further on
