  • What is the cause and solution for SAP error message WRF_ARTICLE_SCREENS081 - Material &1: key fields of component &2 are not unique ?

    Certainly! Here's a detailed explanation for the SAP error message:


    SAP Error Message:

    WRF_ARTICLE_SCREENS081
    Text: Material &1: key fields of component &2 are not unique


    Meaning / Cause:

    This error occurs when you try to create or maintain a material (article) in SAP, and the system detects that the key fields of a particular component (e.g., a classification characteristic, configuration profile, or variant) are not unique. In other words, the system expects certain key fields to uniquely identify a component or record, but duplicates are found.

    This typically happens in scenarios such as:

    • When maintaining classification data (class characteristics) for a material, and the characteristic values or key fields are duplicated.
    • When working with configurable materials (variant configuration), and the key fields defining a configuration profile or characteristic assignment are not unique.
    • When customizing or master data entries have duplicate key combinations that should be unique.

    Common Causes:

    • Duplicate entries in classification characteristics or characteristic values assigned to the material.
    • Incorrect or inconsistent data in configuration profiles or variant configuration.
    • Data migration or manual data entry errors leading to duplicate key combinations.
    • Custom developments or enhancements that do not enforce uniqueness on key fields.

    Solution / How to Fix:

    1. Identify the Component &2:
      The message will specify which component has the duplicate key fields. Check the component (e.g., classification characteristic, configuration profile) for duplicates.

    2. Check Classification Data:

      • Go to transaction CL20N (Change Class) or MM02 (Change Material) and review the classification data.
      • Look for duplicate characteristic values or entries that violate uniqueness.
    3. Check Variant Configuration Data:

      • Use transaction CU50 or CU51 to check configuration profiles.
      • Verify that key fields (e.g., characteristic assignments) are unique.
    4. Remove or Correct Duplicates:

      • Delete or correct duplicate entries.
      • Ensure that each key field combination is unique.
    5. Data Consistency Check:

      • Run consistency checks or reports to find duplicates.
      • Use standard SAP reports or custom queries to identify duplicates.
    6. Check Custom Code:

      • If the error arises during custom processing, review the code to ensure uniqueness checks are properly implemented.
    7. Transport and Data Migration:

      • If the issue appeared after a transport or data migration, verify the source data and transport objects for duplicates.

    Related Transactions and Tools:

    • MM01 / MM02: Create/Change Material
    • CL20N: Change Class (Classification)
    • CU50 / CU51: Configuration Profile Maintenance
    • SE16 / SE16N: Data Browser to check tables related to classification (e.g., AUSP, KSSK)
    • ST22: Check dumps if any related runtime errors occur
    • SM30: Table maintenance for relevant tables

    Related SAP Notes / Documentation:

    • SAP Notes related to classification and variant configuration uniqueness issues.
    • SAP Help Portal documentation on Classification and Variant Configuration.
    • Check OSS Notes by searching for the message number or keywords like "key fields not unique".

    Summary:

    The error WRF_ARTICLE_SCREENS081 indicates duplicate key fields in a component related to a material. The fix involves identifying and removing duplicates in classification or configuration data to ensure uniqueness of key fields.


    If you provide the exact component name (&2) or context (e.g., classification, variant configuration), I can help you with more specific steps.
