Limiting Forwarding on Decision Tasks

[Mark Pyc]

Mark, Mike, I had contemplated something along the lines of what you're both 
basically describing. When wrapped in a subflow it doesn't cause anymore 
impact on the main flow than the proceedure I was suggesting in the post and 
it does get rid of the maintenance of tasks. Assuming the loop is necessary 
I'd be inclined to favour the extra decision choice rather than subtyped 
button simply because there really isn't a functional difference and one is 
completely standard.

However has anyone taken the subtyped dialog a step further and incorporated 
WAPI logic (or equiv) such that the new button really is a forward. That is, 
rather than being in a loop (which generates multiple WIs for each 
iteration) the current decision would be forwarded, but forwarded in a 
custom controlled manner?

Alon, I've done some digging of the BADIs searching on WF, Forwarding, 
Agents but can't see anything likely. Does anyone know the details of the 
BADI or an alternative??

Thanks for input. The current thinking on site is to go with the multi WS/TS 
solution I originally described simlpy because it uses entirely standard 
techniques and will ultimately allow reporting flexibility. The maintenance 
effort is understood and accepted.

I'm still interested in any suggestions for future reference.

Thanks again,
Mark

Mark,

Did you think about using a copy of the user decision task which has the
option 'no forwarding', but then on your decision screen you include a
'forward' button. This doesn't really forward but instead gives a pop up
box to select an alternative approver from a list you generate.  You
could include all this in a loop and do your selected agent assignment
with an expression.  I used this approach at a few customers over the
years.

What do you reckon?

Cheers,

Mark

G'day Wuggers,

It's amazing how seemingly straight forward requirements can tie you up
in
knots.

What I require is the ability to limit the forwarding of a Decision
workitem
to only those people within the same organisation unit. In this case the

Responsible Agents will be based on a combination of Plant and Company
Code,
and forwarding should be limited to those within the same Company.

The standard options for controlling forwarding are:
* General Task (therefore general forwarding)
* General Forwarding (the initially selected agent(s) will be limited to

Possible, but then general forwarding)
* General Forwarding not allowed (initial agents and forwarding choices
limited to Possible)
* No Forwarding (the ultimate in control)

With these as the only techniques the solution then becomes to build a
Task
per Company Code with appropriate Possible Agents. OK so far. With over
800
Company Codes however, alarm bells start ringing - the smallest of text
changes will require extensive maintenance (unless a standard text can
be
included - yet to be tested, esp for multilingual issues).

The next issue is that you want to have a maintenance table identifying
which TS task exists for which company code and use the dynamic Task
binding
within the Workflow step. This is a great idea, but you can't
dynamically
bind Decision tasks!?! This is frustrating because it's the uncontrolled

nature of decision tasks (i.e. no data related security checks) that
makes
this limited forwarding so desireable.

OK, so we can leep that hurdle by dynamically including a sub-WF which
basically just wraps a static call to a standard decision task. So now
we
have a TS and a WS per company code. Workable, but it doesn't seem very
elegant.

Now for the usual bit - Shirely some of you have faced this before...?

The programmer in me wants an alternative to all this maintenance of TS
and
WS objects. Is there anything like a user exit which can control the
possibilities of forwarding?

In terms of how would I know the list of Possibles without refering to
Task
level possible agents - the solution in this case is a custom
Authorization
Object included in security roles (Thanks for the tips Joc, it's a nice
technique). I can programmatically determine who has access to a given
Company Code or Company Code/Plant combo for each logical WF Agent type
(PO
approver level 1/2, Invoice Reviewer ...etc).

Any suggestions or insights greatly appreciated. Hopefully I've just
missed
a completely obvious technique.

Have fun,
Mark
