I’m a newbie using FME although I have also experience with SQL and GIS. I recently started working on a transformer using the AttributeManager. This contains ~ 40 attributes and the goal is to convert part of those attributes based on different conditions, and others attributes based on a same expression: @double(@CurrentAttribute())

I was wondering if there was a method to apply the same attribute expression on several input attributes at once while keeping everything in one transformer.

Thank you in advance!

Hi marianny, I think the transformer ‘ExpressionEvaluator’ is what you want?

You can select the attributes you want to overwrite and use @CurrentAttribute() (last one in FME Feature Attributes dropdown) to do the same calculation on the different attributes
