AW: Error handling in workflow

[Schmidinger, Heinz (Unaxis IT BZ)]

Hi Mark,
 
one way could be to call the Transaction  ... using BDC messages into
message_tab and shift message_tab into container.
additional you can define exaptions which generates additional =
outcomes,
raised depending the conten of message_tab. in such an outcome you can =
set a
display-method to view the message-conatiner or to change the status =
(e.g.
with f.m. SWW_WI_STATUS_CHANGE_NEW).

Betreff: Error handling in workflow
 
Hi,
 
BACKGROUND
My workflow is largely based on template WS2000040 - Approve Trip.
 
The standard is a two step approval process with 2 decision tasks sent =
out
1) Check Trip Facts
2) Approve Trip.
 
I've copied and changed the flow to have a slightly different approval
process again 2 decision tasks are sent out.
1) Approve Trip
2) Settle Trip (Custom code)
 
The workflow is based on business object BUS2089.
I've created a subtype of BUS2089 and named it ZBUS2089, and created a
method ZEmployeeTrip.ZTripSettle which calls a function module (FM) to
carry
out the settle process (submit's a SAP standard program RPTTEC00 (TCODE
PREC)).
 
 
PROBLEM
My problem relates to error handling in the workflow in a real time
environment.
 
When the user chooses to approve a trip, amongst others, locking errors
could occur.
When a user chooses to settle a trip, amongst others, the trip may not =
be
approved.
 
When a user makes a decision - how can the application errors be =
presented
to them
and based on the error change the workitem status i.e. error/inprocess.
 
The approval of a trip is done by using a task that calls a method that =
has
exceptions defined.
I have done the same for the settlement process.
Neither task is a background task. (Approval task was but I changed =
it).
 
My exceptions are being picked up however any exceptions that arise are =
not
presented to the user
but are only available by running SWI2_DIAG.
 
I would greatly appreciate any advice you can offer.
 
Thank's for your time.
 
Kind regards,
Mark
