Screen transactions from Workflow

Fri Aug 9 02:47:44 EDT 2002

Hi Kevin/Lola,
Using an event is infinitely preferable to using GPA/SPA parameter ids
- you cannot rely on GPA/SPA parameter ids as they are affected by
other sessions the user has open not just the current call.
I wouldn't even rely on GPA/SPA in an ABAP program - they are only
intended for defaulting in values and that's it.

Once you have the event you can of course access any data linked
to the event object via its attributes - a much safer and reliable
option.  The documentation on events in the SAP Library help is
extensive and worth reading - plus it includes tutorials for
configuring events.

One way is by using  parameter ids. If you are not familliar with ABAP
statements, I suggest that you take a look at some example of how this is
done from the standard SAP objects. Object BKPF, method create is an
example.Use transaction SWO1.

The above is not a fool-proof method depending on what exaclly your
scenairo is. Could you detail the scenairo you are implementing a bit more?

If you are familliar with ABAP, then you could consider generating an event
after the end user has executed an action (I have only used this in the
OPEN_FI interface). Here you can uniquelly capture each end-user's action
from the system fields and application tables. In your workflow, you could
then wait for this event or use the event as a trigger.
The rule-of-thumb (for me) for when implementing own
workflows/tasks/methods, is to use as guidelines  SAPs'  implementation of
simillar scenairo.

Good luck!

Lola.

Hi Lola,
Thanks for your help.  However, now I have another question.  How can I
access variables in the task container from the screen called in the object
method?

Thanks,

Kevin

Hi May,
Here is one way to do it (a very simple example):
   Create own Object method .
   In the method  call your transaction. eg:

begin_method create changing container.

  CALL TRANSACTION 'MIRO'.

end_method.

   Create your task and select the object and method you have defined. It
   is that simple!

You will of course need to define  input parameters if you need to pass
initial data to your transaction. Export parameters are also needed if you
need to pass back some values to your workflow.

Hope this helps.

Lola.

Hi,
I would like to know if it's possible to call a screen transaction from a
workflow task.  If it is, could someone please explain the steps required
to
do this.

Thanks,

Kevin
