Triggering event with conditions?

[Dart, Jocelyn]

Hi Kevin,
Just to add my two cents worth...
 
My current view is that:
If you are in 4.6 and have access to start conditions (transaction SWB_COND
in
an R/3 system, SWB_PROCUREMENT in EBP systems)
and you can figure out which workflow to start with a logical expression,
e.g. Parked_document.doc_type = 'XX',
then use start conditions, because:
 
1. It's configuration - you don't need to write any code.  Activating the
event
linkage via the start condition automatically adds the matching standard
check
function module to your event linkage (very nice).
 
2. It's easy for users/super users/other workflowers to see and understand
what you have done.
 
3. It's easy to change later on if your business rules change.
 
4. You can be as complex as you like with your logical expression as the
start condition editor handles parentheses, logical and/or/not, etc. - so
you have
quite a bit of flexibility as well.
 
If you are pre-4.6 or deciding which workflow to run is not as simple as a
logical
expression, you can use either check function modules or receiver type
function modules
- either will do.  However, if you want to be sure that you start at least
one
of the workflows every time, then the receiver type function module would
make more sense.
If you don't care, then it doesn't matter but their might be less coding
involved in
writing a receiver type function module.  On the other hand people are
usually more
used to writing check function modules so you might find it easier to do
that.
 
Above all, DON'T create a super workflow that just evaluates a condition,
and then
starts the appropriate sub-workflow.  It's bad for performance due to all
those extra
and unnecessary super workflow instances.
 
Hope that helps.

I do not know if this is possible or not.  That's the reason I send this
message to see if anyone can tell me!
 
Here is the scenario, for example, I have three workflows all triggered
by Parked document created.  The three workflows all have different
tasks to perform based on document types.
 
Is it possible to put a condition against the triggering event such that
for certain document types only the corresponding workflow will be
triggered. Or, I have to build all these three workflows as
sub-workflows and called by a workflow which triggered by parked
document created.
