How to communicate from Lawson to third-party appication?

Hi Asiim,
Depending on which version of BCI you are running, your options are quite different.

One of the huge advantages if you're on LSF9 BCI / ProcessFlow Integrator is that your BCI processes become part of ProcessFlow and you can use the WebRun node to call HTTP, use SQL to interact at the database layer, as well as interacting with SOAP web services.

If you're on Env 8.0, the only way to interact with a third-party is via the Cmd Adapter.
