How to integrate a BSP in a workflow step?

Wed Apr 18 13:23:29 EDT 2007

Patrick, there're several ways you can skin the kitty. Here're a couple
of things that i can think of immediately:

1. create a task for each of your bsp with swfvisu defined, and then use
'task determined by expression' mechanism to pick the correct one based
on the results of the previous background step. It's very
strainghtforward, very small initial development effort needed, but will
require some maintenance if they would want to add a new bsp later
(create new task and all).

2. create a "launcher" iview (bsp or java) and point your task's swfvisu
there. The "launcher" will read the task container, pick the correct BSP
and start it. The launcher can also take care of the workitem handling.
It involves more initial development, but almost maintenance free  - to
add a new bsp they will just need to put it's name in the container.

Hope this helps.

Regards,
Serge B.

Hi Serge, 

Thanks a lot for your explanation. But that is exactly what I would do
if there wasn't the constraint to have dynamic urls. To recap the issue:

- I have several bsp's. 
- My workflow has a background step with a method that determines the
bsp to be called at each step and send emails accordingly. 
- I want to modify that step so that the correct bsp url is returned in
a container element (instead of being sent out by email) and then have
an asynchronous step from which my bsp is executed. 
But if I use the swfvisu mechanism it will always point to the same url,
right? 

Thanks anyway and kind regards, 
Patrick

Hi Patric, 

you can generate an iview from your bsp and then setup the visualization
(SWFVISU) for the task to point to the PCD location for the iview, then
re-register workitems for uwl (function in the portal system admin).
After that your bsp should start automatically when you execute your
workitem from UWL. 

do you plan to run the workitems from sapgui as well? there are
different way the workitem is executed from uwl and from sapgui inbox.
if you plan to use sapgui inbox as well then you'd need to have your
task method to call your bsp and take care of sso. 

also, your bsp application has to handle all the workitem operations
(lock, unlock, complete, etc.) 

hope this help, 
Serge

Hi wug'ers, 

I have an old custom workflow used for access request approval. That
workflow has a rather uncommon logic: it is first sending out a variable
number of emails (through a custom method) each containing dynamically
generated url (the same custom method is generating the url's) pointing
to custom BSP's. It is then followed by a wait for event step, and the
expected event is generated by the BSP's when they are executed by the
users who received the emails. 

Now we are implementing UWL, but we do not want to integrate emails in
it. Therefore I need to have this workflow generating workitems instead
of sending emails. The workitems must call the BSP's dynamically (the
url could be contained in a container element for example), and must be
asynchronous so that they can terminate with the events published by the
BSP's. What would be the best way to achieve this? I tried with webforms
and web service steps, but this is where I am starting to get lost... 

Any help or tip on this will be greatly appreciated... 

Thanks a lot, 
Patrick
