  • What is the cause and solution for SAP error message W0105 - Mark one country schema as standard ?

    SAP Error Message:
    W0105 - Mark one country schema as standard


    Cause:

    This warning message appears when you have defined multiple country-specific schemas in the system, but none of them is marked as the standard country schema. In SAP, one country schema must be designated as the standard to ensure that the system knows which schema to use as the default for various processes, such as tax calculations, reporting, or legal compliance.


    Explanation:

    • Country Schema: A country schema in SAP defines the rules and settings specific to a country, such as tax codes, reporting requirements, and legal regulations.
    • When multiple country schemas exist, SAP requires one to be marked as the standard to avoid ambiguity.
    • Without a standard country schema, certain processes may fail or behave unpredictably because the system does not know which schema to apply by default.

    Solution:

    1. Identify the country schemas defined in your system:

      • Use transaction code OBYZ (for Financial Accounting) or the relevant IMG path for your module.
      • Navigate to the country schema configuration.
    2. Mark one country schema as standard:

      • Select the country schema that should be the default.
      • Set the flag or indicator to mark it as the standard country schema.
      • Save your changes.
    3. Verify the setting:

      • Ensure that only one country schema is marked as standard.
      • Test the relevant business processes to confirm that the warning no longer appears.

    Related Information:

    • Transaction Codes:
      • OBYZ – Define Country-Specific Settings (FI)
      • SPRO – IMG path: Financial Accounting ? Financial Accounting Global Settings ? Tax on Sales/Purchases ? Basic Settings ? Check Country-Specific Settings
    • SAP Notes: Sometimes SAP releases notes related to country schema settings; check the SAP Support Portal for any notes related to W0105.
    • Documentation: Refer to SAP Help Portal for country-specific configuration guides.
    • Impact: Not marking a standard country schema can lead to incorrect tax calculations, reporting errors, or system warnings during posting or reporting.

    Summary:

    • Cause: No country schema is marked as standard among multiple defined schemas.
    • Solution: Mark one country schema as the standard in configuration (e.g., via OBYZ).
    • Result: The system knows which schema to use by default, preventing warnings and ensuring correct processing.

    If you need detailed steps for your specific SAP module or version, please provide more context (e.g., FI, SD, localization country).
