What is the purpose of the Schema Sources parameter on a writer feature type in a dynamic translation?

• A. To define the encoding of the output dataset
• B. To define the destination path where FME will write the data
• C. To define where the writer will obtain the destination schema
• D. To manually define a fixed schema

Answer: (C)

Schema Sources determines where the writer gets the destination schema. In a dynamic translation, the destination structure can come from different places, so this setting tells the writer which source to use to build the output schema and map fields correctly. It’s not about encoding or where the file is saved; it’s about resolving the destination’s schema so the writer writes data that matches the target format. If you want the writer to follow a predefined structure, you select a fixed schema as the source; if you want it to adapt to the destination, you point it to the appropriate schema source.
