Designing Workflow Event Types

If we extract each unique event type from the above table, we end up with the following:


Workflow Event Type
Validate notification - consumption history request
Confirm requester is a valid service provider for the customer's service
Create notification download - send consumption history
Validate notification - supplier switch
Current supplier confirmation
Switch supplier
Validate notification - interval meter switch
Create field activity to exchange meter
Change rate
Create notification download - reject request

Next, we have to determine the algorithm that will be used when each event is activated on its trigger date. We call this algorithm the activation algorithm. An activation algorithm is a stand-alone routine that does whatever you need done when an event is activated. We have populated the following table with brief descriptions of the types of activation algorithms you'd need for the above workflow events.

Note:

The activation algorithms are limited by your imagination (and business requirements). We have provided the activation algorithms you see below as an example; we don't expect you'll be able to use the exact algorithms that we supply. Your algorithms will be based on any number of factors. Be aware that new activation algorithms may require programming. See How To Add A New Algorithm for more information.


Workflow Event Type	Activation Algorithm
Validate notification - consumption history request	Validate consumption history request
Confirm requester is a valid service provider for the customer's service	Confirm service provider is valid requester
Create notification download - send consumption history	Create notification download - send consumption history
Validate notification - supplier switch	Validate supplier switch request
Current supplier confirmation	Create notification download - check if it's OK to switch customer from current supplier
Switch supplier	Switch supplier
Validate notification - interval meter switch	Validate interval meter switch request
Create field activity to exchange meter	Create field activity - exchange meter
Change rate	Change rate
Create notification download - reject request	Create notification download - reject request

Next, we have to determine which types of events can fail. Refer to Some Workflow Events May Fail for background information failure. For those types of events that can fail, we will indicate their failure algorithm in the table. A failure algorithm is a stand-alone routine that does whatever you need none when an event fails. We have populated the following table with brief descriptions of the types of failure algorithms you'd need for the above workflow events.

Note:

The failure algorithms are limited by your imagination (and business requirements). We have provided the failure algorithms you see below as an example; we don't expect you'll be able to use the exact algorithms that we supply. Your algorithms will be based on any number of factors. Be aware that new failure algorithms may require programming. See How To Add A New Algorithm for more information.


Workflow Event Type	Activation Algorithm	Failure Algorithm
Validate notification - consumption history request	Validate consumption history request	Create notification download - invalid request
Confirm requester is a valid service provider for the customer's service	Confirm service provider is valid requester	Create notification download - invalid requester
Create notification download - send consumption history	Create notification download - send consumption history	N/A
Validate notification - supplier switch	Validate supplier switch request	Create notification download - invalid request
Current supplier confirmation	Create notification download - check if it's OK to switch customer from current supplier	Create notification download - reject request due to supplier rejection
Switch supplier	Switch supplier	N/A
Validate notification - interval meter switch	Validate interval meter switch request	Create notification download - invalid request
Create field activity to exchange meter	Create field activity - exchange meter	N/A
Change rate	Change rate	N/A
Create notification download - reject request	Create notification download - reject request	N/A

And finally, for those events whose activation algorithm puts them into a wait state, we have to determine the waiting process that monitors the waiting events. Refer to Waiting Events And Their Waiting Process for more information about waiting.

Note:

The waiting processes are limited by your imagination (and business requirements). We have provided the waiting processes you see below as an example; you may not be able to use the exact processes that we supply as your processes will be based on any number of factors. Be aware that a new waiting process will require programming.


Workflow Event Type	Activation Algorithm	Failure Algorithm	Waiting Process
Validate notification - consumption history request	Validate consumption history request	Create notification download - invalid request	N/A
Confirm requester is a valid service provider for the customer's service	Confirm service provider is valid requester	Create notification download - invalid requester	N/A
Create notification download - send consumption history	Create notification download - send consumption history	N/A	N/A
Validate notification - supplier switch	Validate supplier switch request	Create notification download - invalid request	N/A
Current supplier confirmation	Create notification download - check if it's OK to switch customer from current supplier	Create notification download - reject request due to supplier rejection	Check if supplier has accepted process
Switch supplier	Switch supplier	N/A	N/A
Validate notification - interval meter switch	Validate interval meter switch request	Create notification download - invalid request	N/A
Create field activity to exchange meter	Create field activity - exchange meter	N/A	Check if field activity is complete
Change rate	Change rate	N/A	N/A
