Hi @richardtriesfme, the FeatureReader outputs first a schema feature for each feature type via the <Schema> port and a Dynamic writer feature type can refer the schema feature as its schema source. Try this.

  1. Connect the <Schema> port of the FeatureReader and the writer feature type directly.
  2. In the writer feature type, check the Dynamic Properties checkbox and select "Schema From Schema Feature" as the Schema Source.
  3. If you have set fme_feature_type to the Feature Type Name in the writer feature type, you can leave the Schema Definition Name parameter the default ("Default from Feature Type name above"), like this screenshot. Otherwise, set fme_feature_type to the Schema Definition Name explicitly.

Thanks Takashi,

I believe I have done this now however I am still getting extra attributes in the output that do not exist in the source.cadextractorworking.fmw

I think the dynamic properties setting in your workspace should work as expected. How did you confirm that the extra attributes don't exist in the source feature type?

Ah, I didn't check the User Attributes tab in your writer feature type. In a dynamic writer feature type, it's not necessary to define any user attribute unless you want to define specific additional attributes. Remove every attribute definition here.
