  • 1.  TMF641: Order Item Action, Service State and Service Order Item State

    Hi Everyone,

    Few Questions:

    If we look at the Service State model given in the TMF641 document, it seems that the fulfillment work flow should not just be dependent on Order Item Action, rather it should also consider the Service State that is being requested in Service Order. 
    So if the Order Item has action as Add and Service State is Designed, the fulfillment workflow should only execute the Design activities.
    Similarly,  if the Order Item has action as Add and Service State is Active, the fulfillment workflow should only execute the Design, Reserve and Activation activities.
    Is this understanding correct?

    Another question: How Service Order Item States are related to Service States?
    if in a particular Service Order, the Order Item has action as Add and Service State is Designed, the fulfillment workflow would execute the Design activities and Mark the Service Order Item as Completed?.
    In such case, how the request would come to make the service active - new POST with Order Item action as Modify and Service State as Active?
    OR
    the 1st Order needs to be kept in IN PROGRESS state and the request to make service Active will come as PATCH?

    Hello Prashantkumar 
    For my perspective you got it.
    The service order item describes a request to performean action to a service. The service state is part of this request.
    the service order item state is use to track the action progress. There is in fact not really a hard link between service order item state and service state.

    Regarding your second point.
    You 'll have a POST serviceOrder
    with an item with action add for a service to be in state designed.

    Suppose everything goes well
    The service order item state is completed
    The service #48 in your inventory in designed state.
    (if thing goes bad the service is not created and the service order is failed state)

    Late you want to activate it.
    So here you'll POST a service order (a new service order)
    with an item with action change for  service #48 to be in state active.

    Hope it helps

    Hi

    If the Service state attribute in the service order is the requested end-state, how is the progress of the ordered service (e.g. designed->reserved->active) made available to the consumer?

    Thanks in advance

    Hi

    I would suggest that this could be communicated by events relating to the state of the service order (ServiceOrderStateChange). Possibly you might want to go deeper, to the level of state on service order item.

    Hope it helps

    Have you considered using the serviceOrder.serviceOrderItem.state?

    Hi Dan

    My understanding is that the ServiceOrderItem state is to report/track the progress of the order item. Whereas the Service state is to report track the progress of the Service

    The state values for both are completely different - so are not interchangeable. Also the ServiceOrder state is a consolidation of the (potentially) multiple ServiceOrderItem states

    My understanding from the Forum discussion (and the definition of the Service state in v4 of the Service Order API) is that the ServiceRefOrValue state attribute can be used by the consumer to request that the OSS provide a Service to the end-state requested. This impacts the order processing - i.e. when the  order has been 'satisfied'. For example, if the requested Service defines a state = 'reserved', when the Service design has been completed, the ServiceOrderItem is 'Completed'

    What we want to do is provide the consumer with the state of the Service they have ordered as it progresses - i.e. feasibilityChecked, designed, etc. Originally we had planned to use the ServiceRefORValue state attribute UNTIL we realised that this is the requested end-state and NOT for reporting/tracking the state of the requested service

    Having discussed this internally, we think that the best approach is to retain the ServiceRefOrValue as a record of what was requested and a separate - but linked - Service entity to track the progress of the Service that has been ordered. Hopefully this is a common way of implementing it to support interoperability

    Are you not planning to maintain the service (instance) in the inventory?  In our implementation, the service.id is updated in the serviceOrder response and so we are able to query the service.state directly from the inventory, either using the TMF638 API or through the ServiceStateChangeEvent from Kafka.

    Hi Dan

    Whether we create the Service instance as part of the ServiceOrderItem/Service or include it in the Service Inventory, we still need to keep a 'record' of the Service ordered, including its expected end-state, and an instance of the Service to track its progress.

    We decided to track the requested Service as part of the ServiceOrderItem and only 'transfer' it to the Service Inventory once we have made sure we can deliver it and have 'contracted' to do so with the consumer (e.g. the resources from our 3rd party Service Providers are limited and can often be over-subscribed, so a significant number of service orders cannot be accepted)

    Kind Regards
