Variables from the identification section can be referenced by $parent. during connection building. Is the same also possible with variables set in the extension section?
Using $parent doesn't show up any of the variables I defined in the extension section nor do I find another way to reference them. Do I miss something here or is the extension section only good for populating attributes of the CI type?
Solved! Go to Solution.

I raised a HI ticket and got an answer:
- Variables from Extension Section are not available in Connection Section because Extension Section is run after Connection Section. The run order by the plattform is as follows: Identification Section, Connection Section, Extension Section
- BP for new connections: New connections should be done in the Connection Section
My take away from this is:
- ServiceNow recommends: Don't use the Extension Section for creating new connections. Use Connection Section instead
- To gather information for the Connection Section
- the Extension Section is useless because you cant reference information gathered in the Extension Section in the Connection Section (Reason: the plattform runs the Extension Section after the Connection Section).
- I've to modify the Identification Section to gather information for the Connection Section (which means the pattern will get flagged)

The extension section can be used for both populating additional attributes and create new relationships.
All data in the extension section is not available in the connection section. I dont know why, tough, or if there is any way of achieving that.

Is that best practice to create new connections in an extension section? Does the information that data in extetnsion section is not available in connection section cam from ServiceNow or is that you ownexperience?
The only way to expose the vriables from the extension section is to use that libary in the connection section again. To me that's more a workaround.

It is best practice to create connections in the Connection section. What i mean was creating relations (for instance server -> disk) can be done in the Extension section.
I dont believe there are any technical obstacles in creating connections from the Extension section, although this isnt the purpose.

So the important thing to remember here is why there are extension sections now. The purpose of them is so you can add to the Service Map Pattern without flagging it for updates. It's also so you can share them across multiple patterns as well. I think the best practice going forward will be to do as much as possible in the extension section simply because of the fact that it gets away from flagging for updates but as it stands now I use them sparingly but hope to in the future switch over to using them more often then creating new connection sections.
