AW: Workflow condition step returns wrong value

[Quenzer, Kenneth]

Hi Thorsten,
 
I was mistaken in my previous answer.  The problem that I ran into was =
in a
workflow that executed a task which created a business object and then =
the
subsequent step attempted to access an attribute of the newly created
business object.  In some cases the step was executed before the =
database
tables were updated which caused the step to fail.  This sounds like a
different problem than what you are referring to.

Hi Kenny,
 
right, therefore the function module that raises the event in update =
task
must be called as the last thing, i.e. after all the insert, update =
etc.
statements. Then, with a commit work right after that function module, =
the
event is "committed" (raised) after the database contents have been
"physically" updated (in update task, right before the event). If it's =
not
implemented this way by SAP, it's plainly wrong.
 
Please tell me the business objects and events where you encountered =
such a
problem. My former workflow development colleagues in SAP will =
definitely be
happy to know about this.

Hi Thorsten,
 
I have experience this problem before and it was my understanding that =
it
can occur because most updates to the database are executed =
asynchronously
in an update process on the application server.  Therefore, even if the
event is triggered at the same time that the SQL statement to insert =
the
record is executed the actual update to the database may not have =
occurred.

Patrik,
 
if in one SAP application, the event is triggered BEFORE the =
application
data are written on the database, this is worth an OSS message to SAP. =
It
mustn't occur.
 
Could you tell me which business object and method you're talking =
about?
 
Cheers,
 
Thorsten

Thorsten, Sarah.
 
I agree with what you say Thorsten. We did the workflow branch solution =
and
saw
alot of RFC's. We changed that to a checkfunction and the load did go =
down
drastically. This is ofcourse depending on the type of workflow, the =
number
of
flows started and the percentage of flows that are terminated ofcourse.
 
One issue that also needs to be adressed concerning this is a problem =
with
synchronisation. In some applications the, for example CREATED, event =
is
triggered before the database update has been done. This means that the
access
to the object is not succesful in the check function. Sometimes this =
works
with
the first solution Sarah suggests since the slowness of the RFC could =
alow
the
database update to finish, but that doesn't seem like a very stabil =
solution
really.
 
We had to build an exit for one application to check a status for one
created
object and skip the triggering of the created event within the =
application
instead of with the check function just of the above described problem.
 
Whats your opinion on this?
