Want to trigegr an idoc only if done manual intervention and not automatic

We have a requirement where the idoc needs to be generated only if a user creates the it, and not through automated process.

The particular idoc is the delivery idoc.We can manually create delivery, then only the delivery idoc should be created,else it should not be created.We have process in place by which you can automate the creation of delivery by inbound processes.We do not use any workflow in oursystem.

Any Help would be greatly appreciated.
