How to know if a workflow instance have already been executed

Sun Jun 19 19:48:35 EDT 2005

Hi Kjetil,

you are correct, my pseudo-code is actually like this:

1 - bus2081.completedtorelease 
2 - Receiver FM is called 
3 - Within FM: 
if withholding tax is applicable then 
------ if withholding tax approval workflow has not been executed for this 
invoice then
-------------- start withholding tax approval workflow
-------else 
-------------- start release for posting approval worlflow  
------ end if 
else 
-------- start release for posting approval workflow 
end if 

It realy seems to be a timing issue. When I use SWUE to test it, it works 
fine.

I guess the problem is that the last step of the withholding tax approval 
worklow is an asynchronous task. In the last step, the AP guys complete 
the withholding tax details in the invoice and then press the Save as 
Complete button. When this happens, the event completedchanged is raised 
and the workflow is completed (completedchanged is a terminating event for 
the last task of the withholding tax approval workflow); then the event 
completedtorelease is raised but it does not trigger my next workflow, 
actually, looking at the event trace log, the name of the receiver type is 
() - it doesn't start any workflows whatsoever.

There is anything I could do to delay the completedtorelease event being 
published so quickly? I tried using the event queue, but the same problem 
happens. 
Any other ideas???

Much thanks,

Cristiana

RE: How to know if a workflow instance have already been executed

In your pseudocode you have a bug as far as I can see, but I suppose that 
doesn't apply to the real code. You state that if the withholding tax 
approval has been executed you should start the withholding tax approval
------ if withholding tax approval workflow has not been executed for this 
invoice or it is not set to completed nor to started then 
-------------- start release for posting approval worlflow 
-------else 
-------------- start withholding tax approval workflow 

Perhaps you should just check that the workflow is not cancelled? If it is 
the type W item you check it can be selected (reserved) as well, and 
committed if confirmation of completion is required. It can of course also 
be in error or cancelled. If it is the type F item you check I suppose 
completed and ready should cover what you want.

You can usually check if there is a timing issue by debugging. If it works 
when you are debugging and doesn't work otherwise it is most likely a 
timing issue. Otherwise you should dump the information you find about the 
work items to see what statuses are reported.

>From MIR7, upon selecting button Save as Completed, obj type/event 
bus2081.completedtorelease is published. 

In my client, this event can start more than one customized workflows: 
withholding tax approval and release for posting workflow. 

I have a receiver FM that is testing if the withholding tax approval 
workflow should start (based on Vendor master data); if it doesnt then the 
release for posting workflow starts. 

Withholding tax approval wf : goes to the agent to enter details on 
regards to withholding tax and then goes to AP. The AP guys then enter 
whatever they have to in the invoice and click Save as Completed - 
bus2081.completedtorelease is published and bus2081.completedtoreleased is 
published. 

I need to control that workflow for withholding tax approval does not 
start again. 

How in my receiver FM can I check if the withholding tax approval workflow 
has been completed or it is being processed ? The withholding tax approval 
should only start once (if applicable, depends on vendor master data). 

If the vendor in the invoice is subject to withholding tax, I am using FM 
SWI_WORKITEMS_OF_OBJECT_GET to retrieve all the workflows that have 
started for my objkey and then checking if there is any instance of the 
withholding tax approval that is set to either 'completed' or 'started' - 
but I think the events happen too fast and table swwwihead doesn't get 
update on time. 

The client would like to have the users always using button Save as 
Completed. 

1 - bus2081.completedtorelease 
2 - Receiver FM is called 
3 - Within FM: 
if withholding tax is applicable then 
------ if withholding tax approval workflow has not been executed for this 
invoice or it is not set to completed nor to started then 
-------------- start release for posting approval worlflow 
-------else 
-------------- start withholding tax approval workflow 
------ end if 
else 
-------- start release for posting approval workflow 
end if 

Any ideas on how to achieve what I need? 

Much thanks for any help!

Regards, 

Cristiana
