create a viewpoint in the operational analysis level

Hi everyone,
I want to create a viewpoint in the operational analysis (OAB diagram) and this viewpoint must recover the entity name and the operation name where it’s located the viewpoint. I tried to edit the file. diagram.vptext but I didn’t succeed in it, I have always a red underline at Emde.ExtensibleElement.ownedElementExtensions

  1. how I can create viewpoint in operational analysis
  2. in which file I should create my method and how I can do it
    Regards,

Hello,
Could you explain more in details what you want to do?
I do not understand what you mean by “viewpoint must recover the entity name and the operation name where it’s located the viewpoint”…
