How to resolved this error.? I have attached screenshot.
Your structure of the file which you are using for import is not the same when you created the definition, Might be mismatched column names. Check source file if it matches with your action.
Pls check the Dimension of Data hub model, which you are trying to import in supply chain model.
You are almost near to complete this step.
Hope this helps
Try on a different browser (Chrome, Firefox, Edge, Safari, IE, Opera, etc). Sometimes it can be browser specific. Try in a private window in your browser of choice (e.g. Chrome's Incognito mode, or Firefox's Private Window). Sometimes we find that certain extensions can affect the upload option and create errors.
