Hi Andre,

 

 

Feature attributes such as Excel column values cannot be treated as user parameters in the Main workflow anyway, but you can pass the attribute values to a custom transformer through published parameters defined in the Custom Transformer.

 

In the custom transformer, once add a transformer containing a parameter with a preferable type (can accept attribute value) temporarily, and create a published parameter from the transformer parameter.

 

Just be aware that the parameter will be deleted automatically if you deleted the temporary transformer before referring to it from the parameter of a non-temporary transformer.

Hi Takashi,

 

 

Thank you for your answer. I am not sure if I understood you correctly but this means there is no way (without a second workbench containing a WorkspaceRunner) to set the parameters of a custom transformer directly by using an external Excel dataset?

I mean that the attribute values which have been read by the Excel reader can be passed to a custom transformer through its parameters (published parameters of the custom transformer), if you defined the parameters in the custom transformer definition.
