Getting this error and I'm not exactly sure what it means. I am trying to pull my data together so I am using a Basic Data Profile tool and then going straight into a Cross Tab tool. What I was expecting to happen is that each row would be one column worth of data. It appears to be when I am trying to group my Cross Tab.
The error you are seeing is due to you having multiple Name values that are the same ie FieldName, FieldType etc. I'm not sure what you mean by using a cross tab to get "that each row would be one column worth of data" because you will have too many dimensions in your data. A solution I could see working would be to filter based on the FieldName column and then cross tab those. That would allow you to pivot your data and then union it all back together and that would give you some better analytics on your data. If this isn't what you were shooting for let me know and we can find what solution you are looking for.
So I came up with this solution and now the error makes sense. Add a select tool between the basic data profile, and the cross-tab tool. Change the FieldName column to anything else (I actually used that but you'll probably have a better name) and then run your workflow. Everything should come up peachy! I've attached the workflow that I used to get the solution.
Prior version of Alteryx did not cause this error. This is particularly problematic when trying to crosstab JSON_Name data into headers. With an unknown # of headers and names these often conflict with existing fields. Many flows have broken with the upgrade.
It was a Null field giving me trouble, and since I didn't really need that field I just left it unchecked in the "Group Data by these Values" configuration section of the Cross Tabs that were giving me trouble.
