    Hi lucasgalde ,

    Please chcek if these two scenarios are inadvertently causing the error:

    The error message suggests a data type mismatch between your pre and post refresh data. For example, a column that previously contained datetime values is now containing only date values which may inadvertently cause the error.

    Another possible reason for the issue, as you mentioned not encountering the error in Azure SQL Database and Lakehouse, could be that the data includes a datatype that is unsupported by Fabric Warehouse.
    Document to check what data types are not supported by Warehouse:
    Data types - Microsoft Fabric | Microsoft Learn
