Workflow :Mode of invoking work flow process?

Q : Mode of invoking work flow process?

Ans : 1.Local Synchronous
2.Remote Synchronous
3.Remote Asynchronous

There are two BS to invoke a work flow process
1. Work flow process manager
2.Server Request

you can use both Business services in Scripting / RunTime.

if you are using Workflow Process manager then it will be local Synchronous.

if you are using "Server Request" then you can pass parameter (Syncroous or async)
.Server Request in sync mode wait for responce from SR Broker while aSync never waith for any response from SR Broker.
