Dynamic view with technology

[0xBradock]

Hello,

I have a system that contains many procedures and I wish to add steps to a dynamic view and specify the name of a procedure.
I image that using the [technology] of a relation could be an alternative. I accept other suggestions.
So, in the image below instead of JSON/HTTPS I would like to display procedure_alpha.

In the dynamic doc I found the spec for a relationship.

<element identifier> -> <element identifier> [description] [technology]
<relationship identifier> [description]

I amd trying:

A -> B "Some description" "procedure_alpha"

But when I try to add a technology it fails with A relationship between A and B with technology procedure_alpha does not exist in model.

Am I missing to declare something?

Thanks,
