Hello Experts,
I faced problem with Running a Smart Discovery in STEP2 of Tutorial below.
Augment your Story with Smart Features | Tutorials for SAP Developers
As you can see in the image below, the charts are not displayed due to two errors.
Please tell me how to resolve each error and display the charts.
Error1

Messages:

Error: [Extended dimension processing error : Mapped column LBH_2 doesn't exist in the extended dimension view
_SYS_BIC:/37122552-5614-4427-8701-215440825732::[QUERY]]
Error2

Messages:
Unable to fetch data due to duplicate dimension bindings.Remove the duplicate dimension in the Builder or select a different Input Control dimension.
I don't know how to remove the duplicate dimension bindings in the above message.
Also, I don't want to change Input Control dimension because I want to follow the tutorial.
Please tell me how to resolve.
Additional Information
You can download the data source file from the site below.
Click "sample dataset" link in "Prerequisites".
I imported that file into SAP Analytics Cloud.
