  • 1.  Best practice for modeling Fulfillment Lead Time in TMF620 to support TMF622 Expected Completion Dates

    Posted Jan 27, 2026 09:36
    Hi everyone,

    I am looking for the standard way to define "Fulfillment Time" at the Catalog level (TMF620) so that it can be used by an Order Management System to calculate the expectedCompletionDate in TMF622.
    Since there isn't a native "leadTime" attribute in the Product Specification, is it recommended to use a ProductSpecCharacteristic (e.g., "delivery_days"), or should this be handled via an SLA entity reference within the ProductOffering? I would appreciate seeing how others have mapped catalog-driven fulfillment durations to the ordering process.
    Thanks.

    Hi Rosalin,

    I don't know if this relevant for you, but I will give you my view on this.

    The attribute to use for your use case is productOfferingTerm. A Term is basically a named duration.

    Named durations can easily be used in calculations involving time. Calculating a expectedCompletionDate is definitely one of the calculation using an "expectedDeliveryDelay". 

    Common other date related calculations could involve minContractDuration used during termination processes. or indeed various SLA timers like maximumResponseTime, maximumRestorationTime, ...

    I hope this helps and is still relevant.

    Regards
