  • What is the cause and solution for SAP error message CNV_DMC_UI_FW_EXCEPT008 - Eather the external date &1 or its data type is invalid ?

    The SAP error message CNV_DMC_UI_FW_EXCEPT008 typically indicates that there is an issue with the external date format or its data type when using the Data Migration Cockpit (DMC) in SAP. This error can occur during data migration processes, particularly when the system is trying to interpret or validate date fields.

    Cause:

    1. Invalid Date Format: The date provided does not match the expected format. For example, if the system expects a date in the format YYYY-MM-DD and receives it in DD/MM/YYYY, it will trigger this error.
    2. Incorrect Data Type: The data type of the field being processed does not match the expected type. For instance, if a date field is expected but a string or numeric value is provided, this error can occur.
    3. Null or Empty Values: If the date field is null or empty when it is required, this can also lead to this error.
    4. Localization Issues: Different regions may have different date formats, and if the system is not configured to handle these correctly, it can lead to errors.

    Solution:

    1. Check Date Format: Ensure that the date values being imported match the expected format. You can refer to the documentation or configuration settings in SAP to confirm the required format.
    2. Validate Data Types: Make sure that the data types of the fields in your source data match the expected data types in the target SAP system. For date fields, ensure that they are formatted as dates.
    3. Handle Null Values: If the date field is optional, ensure that your data handling logic accounts for null or empty values appropriately.
    4. Data Mapping: Review the data mapping configuration in the DMC to ensure that the source fields are correctly mapped to the target fields in SAP.
    5. Testing: Before running a full migration, test with a small subset of data to identify any issues early in the process.
