Hi folks
I was reading through the "Best Practices Guide" tonight and came accross this paragraph. Could someone help me out with a quick question?
By the way.. This is a great support pack

Repeatable business processes: Some business processes are repeatable; they
run the same way every time, with the exception of handling for errors and
branching based on business data. However, sometimes a ‘process’ does not
follow predetermined rules. Such a process is much more difficult to model, and
might not be a good candidate for MQ Workflow. However, do not overlook
capabilities, such as dynamic subprocess invocations, when considering if the
workflow engine is a good fit for the business process. |
Can anyone tell me what "Dynamic Subprocessess Invocations" are? [/url]

From my understanding.
A repeatble process has three activities A1, A2, A3.
By having a noop activity as a router with transitions to A1,A2, A3 (these are controlled by a data member like TargetActivity (eg: TargetActivity="A1" , TargetActivity="A2" etc).
In any repetition, we can directly jump to any activity in the process. This can be controlled in runtime. |

Dave:
A dynamic subprocess is invoked "From Container" The idea being similar to any "from container" attributes... you have some previous activity make a decision as to what subprocess to invoke based on the current container data and map the proper process name to the "From Container" member.
The only issue is a "Process Not Found" at run time should the process not exist. This will put the "Process" activity into the inError state with an appropriate error message.

Don't u think the data structure need to be same for the dynamic subprocess ?

Manoj:
You have to plan for these Dynamic subprocesses, and Map appropriately... I agree with you that this can be a challange.

| You can see page 25 in Workflow Best Practices Guide where subprocess late binding is explained. |
