Does K2 allow me to provide custom functions by developing it directly using WWF, to do some scheduled actions on some work flow instance.

Kel,

You can include WF schedules using the Server Event (WF) event.  Although this has some interesting possibilities, I haven't seen anyone use it as the blackpearl toolbox is pretty rich.  There are a number of ways you can add custom functions depending on what you want to do.

I'm not sure exacly what you mean by scheduling, but yes, you can schedule workflows to run on a periodic basis.  Right now this functionality is only available through the scheduling API, but UI support is coming in the future.  If you are talking about scheduling activites within a workflow, that can usually be accomplished with a combination of rules on activities.

DavidL,

Thanks a lot for your response.

Here is what I would like to do. I would like to have a "scheduled" task, hopefully I can set it up in K2 server. The task checks all the instances of the workflows in K2 server at 1am every day. Then depends on the status of each instance, it performs some actions like sending an email to remind to the right person, cancel the instance or something else.

Could you please tell me how to do these in K2 way? Or point me to the right place that I can learn. Thanks again.

Hello Kel.

1. Does K2 allow me to provide custom functions by developing it directly using WWF?

Yes.  If you wish to use WF directly you can use the Default Server Event (WF) activity.

2. Does K2 server support scheduling to perform actions on some work flow instances?

Could you describe your requirements in greater detail? K2 provides time based functionality like Start Rules and Escalation Rules at the Activity level, which may be of value depending on what it is you are trying to accomplish.

Hi Matt,

Generally the type of functionality you describe is handled via in K2 via a Activity "Start Rule".  A "Start Rule" provides the workflow developer to have more control about when an activity instance begins.  Start Rules are always time based; they provide the ability to configure either a timespan to wait (in your case it sounds like 5 days) or a specific date. It also has the ability to leverage working hours or  "Zones" to be able to calculate business days.

HTH.

Hi,

If I want to query all activities due next monday or, better yet, any activities due after a particular date, what would I use in the API? I'm not clear on whether the activity instance exists before the 5 days is up or whether something else exists that then creates the activity instance.

Thanks

Matt
