Build your First Workflow - website exercise

[stickysaj]

Hi I’ve been following the steps on the website to build your first workflow but when it comes to Row Aggregrator step 6/6 I am unable to view the the Dict-Volume in the Category column and only Amount is shown. What am I missing?

Hello @stickysaj ,
Welcome to the KNIME Community!
Glad to know that you are building your first workflow.

Did you convert the column type of column Dict-Volume from string to number, as shown in the screenshot below?

Thanks,
Sanket

Yes I did as per the screenshot you sent.

Okay!
Could you please share the snapshot of the configuration window for the next steps/nodes?

Thanks,

Hello @stickysaj ,
Thank you for sharing those screenshots.
In the second screenshot, the configuration window of the Value Lookup node, if you see the “output” section, the column “Dict-Volume” is excluded (falls under Excludes) and “Dict-Item” is included. It should be the other way around. If you swap those two columns, then you will get the “Dict- Volume” in the Row Aggregator node.

Thanks,
Sanket
