Hello,

to simplify/reproduce my problem:  

I added a User-Parameter on my Attribute-Remover:
 

Which grants me a choice to select which to ignore, but (same as here Attribute Remover does not work with User Parameter | Community 8 years ago) it only removes the values and not the attributes, so when I write it into my database or even a new excel, it creates unneeded columns.
Manually selecting attributes in the Attribute-Remover works fine, this only happens when using user parameter.

 

Am I missing something or is there another way?

P.S. I also tried AttributeKeeper with User-Parameter, but then they’re unexposed, so I would have to iterate via AttibuteExploder, which simply seems unnecessary complicated...

Okay, I’ve found this answer from Mark FME remove missing values

And the solution is to use SchemaScanner and DynamicSchemaDefinition in my writer
 


Still confusing that the user-parameter approach does not offer the same result as the manual one in AttributeRemover.
