Error Importing MVLVTransformer via CSV in ArcGIS Pro

[ShamilaAllahYariAsliArde]

Hi everyone,

I'm currently working on importing LVFeeder and MVLVTransformer as Subnetwork Controllers in ArcGIS Pro. The import process works perfectly for LVFeeder, but I'm encountering an error when trying to import MVLVTransformer.

When I manually import the data, there are no issues. However, when I attempt to import it via a CSV file, I receive an error.

Has anyone experienced this issue or have any suggestions for resolving it?

Thank you!

One of the global IDs in that file references a feature with an asset type that does not have the subnetwork controller category.

Join the CSV file to your device table and review the asset types of all the matches to find the feature causing your problem.
