Restart Workflow for condition

[arsiasmi]

Hi

I have completed the workflow design, however i need to reset the workflow to the starting step if there are any changes in the records.It has to be a background task where the task will check the change in fields from CDHDR/CDPOS, then is should trigger reset of workflow.

Any help will be appreciated.

Thanks

Usually I prefer to cancel the old and start a new workflow.

Add a CHANGED event both as a triggering and a terminating event. Every time there is a change, this event will cancel any active workflows and start a new one. It makes logging simpler, as you will see multiple workflows in a status CANCELLED and one COMPLETED.

You can link events to change documents using tx SWEC. Plenty of documentation and info on here on how to do that.

Hi Mike, I know it is an old post, but, I have one concern about your advice... If the same event (CHANGED) trigger the workflow and terminate it..When the workflow starts it not going to end immediately?

Thanks in advice!

mateocanoc no, because the terminating event has to happen after the WF has started.

In technical terms, once all listening event receivers that exist at the time the event is processed are triggered, the event is ‘consumed’ and complete.

Hi, Arsalan,

One of possible ways is to use BOR events.

It is possible to:

• create BOR event when a change document created (possible alternative to background task solution that you describe) - SWEC transaction (more information here: https://help.sap.com/saphelp_nw70ehp3/helpdata/en/4f/3d079870421617e10000000a42189b/frameset.htm )
• restart workflow when BOR event is received ( https://help.sap.com/saphelp_nw70ehp3/helpdata/en/4f/307c0684422787e10000000a42189d/content.htm , search for 'The workflow is then restarted' on that page )

Hi Egor Malov

Thank you for response. However, your reply does help in understanding the workflow but my requirements are different. I have designed 2 workflows, one will be triggered when record is created & the second will be triggered when the record is changed. My requirement is, when the record is changed, the workflow that is triggered on create event should get reset i.e. all work items in SAP Inbox related related to the record should be cleared.

Hi, Arsalan,

I think I get the idea better now - when the record has changed, nobody wants to know it had been created anymore.

Trying to get this requirement closer to SAP workflow features and terminology, I think, what you could do to the first (i.e. the one that runs at creation) workflow instance is *cancel* it (with all its workitems).

If you choose the BOR events way of implementation, you can 'cancel workflow' just as easy as you can 'restart workflow' (as desribed above): it is just another option of the very same drop-down field.

If you choose another approach you can use the SAP_WAPI_* function module, that cancels a workflow.

*one more note on BOR events: if you work with some standard business object, it is possible that it is already capable of firing BOR events like CREATED or CHANGED. It can take some configuration to enable. Check this, and you'll probably won't need to process change documents.

Hi ,

Wait for the change event in a branch of fork of Create Workflow.It will get logically deleted

Thanks

Hi Ram

Please help in case you have some documents to proceed.

Kind regards

Hi Arsalan,

Its simple,In the create workflow just add a fork with 2 branches and make 1 necessary,one for the Wait step and the other for your current flow.

Any standard Documentation on Fork and Wait will help you here.

Thanks

Hi

Thank you Egor & Ram.

I resolved it by using WAPI's

1--> SAP_WAPI_WORKITEMS_TO_OBJECT

2--> SAP_WAPI_WORKITEM_RECIPIENTS

3--> SAP_WAPI_WORKITEM_DELETE

Hi,

It would be better to model the solution in your workflow template by using forks and events and wait for events. The triggering can then be done with SAP_WAPI_CREATE_EVENT.

Thank you Rob,

Please help me with a proper document(if available) to proceed.

Indeed using fork & wait proved to be easiest solution.

thank you
