Implicitly converting values into the required type does not address the issue of case sensitivity in the column. The problem arises because Power BI, depending on the data source and model configuration, may not handle case-sensitive data as expected. Undefined values and errors may occur when case sensitivity isn't correctly managed.

Normalizing the casing in the source query or Power Query Editor will resolve the issue of undefined values and errors caused by case sensitivity

No, this solution does not meet the goal. Implicitly converting values into a required type would not resolve issues related to case sensitivity in DirectQuery mode. This solution might actually cause more problems or errors because: - Case sensitivity issues are related to text comparison and matching, not data type conversion - In DirectQuery mode, operations are pushed to the source database, and implicit conversions might not handle case sensitivity correctly - Implicit conversions could potentially create more undefined values or errors if the conversion fails

I believe the answer is correct as case sensitive data would need to be checked in the source system or explicitly handled in a query with an UPPER() or similiar function
