Feature Reader - Pass on Schema Attribute to the Generic Port

At the bottom of the FeatureReader fold out "Attribute and Geometry Handling" and choose "Merge Initiator and Result".

thank you, @nielsgerrits​, that did the job.

I am now trying to understand the logic behind. I initially had "Only use result". I have to read what the difference is. Thank you again,

From the documentation:

Merge Initiator and Result: Output features will contain all of the un-conflicted attributes from the results of the read as well as any un-conflicted attributes from the Initiator feature. This mode will handle conflicted attributes based on the Conflict Resolution parameter.

Only Use Result: Output features will contain only attributes resulting from the read.

Only Use Initiator: Output features will contain all of the attributes from the Initiator feature, but none of the attributes resulting from the read.

Prefix Initiator: Output features will contain attributes resulting from the read, as well as attributes from the Initiator feature but with the Initiator attribute names prefixed with the Prefix parameter.
