Open APIs

Dears,

In the resource model of both TMF640 and TMF641 it is possible to associate a Characteristic to a ServiceRelationship.
Surprisingly, though, in TM641 there is no Characteristic associated to a ServiceOrderItemRelationship.

So, basically in an service order I can define a characteristic if my service refers to a service (instance) that is already in the service inventory, but I can't define a characteristic if my service  refers to the same service that is not yet instantiated (as it's in the same service order). 

Is this a gap in the API or there is a reason for this discrepancy?

If I mirror this with product order, we can do what you're asking.

OSS is where TMF has most experts, so let's hope they will reply to you.

Thank you for your reply, Matthieu. 

This sounds as a clue that Characteristic may be associated in future to a ServiceOrderItemRelationship in TMF641.

Is there any TMForum that could provide his feedback on this?

Thanks!
