Sum attributes for each record

Assuming this is what you are after, so adding up multiple attributes from the same feature

Inefficient way

• Use AttributeExploder to explode the attribute into features per attribute
• Get rid of any features that contain an AttributeName you don't want to sum (e.g. format attributes)
• Aggregate based on some original record id and sum AttributeValues

Efficient way

• Use python

Another way

• If all the attributes you want to sum share a common prefix, you can use a ListPopulator to build a list followed by a ListSummer. You can use a bulk attribute renamer to add the prefix if it doesn't already exist and remove again later

Actually the ListPopulator doesn't appear to work correctly with a BulkAttributeRenamer in front of it...

What about with ListExpressionPopulator instead? I'm sure I've done the same technique like this in a workspace with BulkAttributeRenamer + ListExpressionPopulator?
