Methods AFTER work item execution - how-to?

[Sheldon Oxenberg]

Hello Rick,

I believe you can successfully change workflow container elements with
Methods AFTER work item execution.

The key information to be aware on page 470 in Practical Workflow for SAP
are:
- You can only use automated binding, i.e. the method container of the
step's task-based method is passed to the after method.
- After methods are called modally, i.e. as if they were extra steps in the
same session as the work item.
- After methods can be used to manipulate the method container if you wish,
to influence the main task-based method.
- After methods can be used for such activities as:  Converting values
returned by the work item.

So, if your main Task-based method were programmed to export 'zMyValue' to
the Task container (method to Task binding),
and if your Task were defined to export 'zMyValue' to the Workflow
container (Task to Workflow binding),
then you have configured the main task-based method container to pass an
initial 'zMyValue' (regardless of the value passed).
If you test this configuration, you should see this initial 'zMyValue' if
you inspect the WF Template container after execution.

Then, if you configure your After method, at execution time it will receive
the main task-based method container with 'zMyValue'
(regardless of the value initially passed from the main task-based method),
and then your line of code
SWC_SET_ELEMENT CONTAINER 'zMyValue' 'Y' should successfully change the
value passed to the Workflow Container.
If you test this configuration, you should see the changed 'zMyValue' if
you inspect the WF Template container after execution.

Good luck.  Have a nice day!

Regards,
Sheldon

G'day Rick,

I'm willing to be blown out of the water on this one, but I'll reply
since it's Friday arvo and you might not get many other responses.

I don't think you can reliably use import or export parameters on
secondary methods. They are intended really only for display methods
as far as I'm aware. This is another one of those cases where ugliness
in the builder can't be avoided.

Again, I'm far from confident on this one....

Have fun,
Mark
