How To Fix UGMD567 - Data loss in the records with the identical key &2 in table &1


SAP Error Message - Details

  • Message type: E = Error

  • Message class: UGMD - FIN Master Data: Messages

  • Message number: 567

  • Message text: Data loss in the records with the identical key &2 in table &1

  • Show details Hide details
  • What causes this issue?

    The fiscal year variant conversion in database table &V1& created data
    records with the same key: &V2&. The table key includes time references
    (for example, the fiscal year and period in hierarchy tables).
    Two or more data records with different fiscal years and/or periods were
    converted with the same target time periods. One possibility may be that
    the target fiscal year variant has less periods or less special periods
    than the source fiscal year variant.

    System Response

    Only the first data record with the key &V2& will be saved in converted
    form in the database table. Consequently, database table &V1& will have
    a lower number of entries after the conversion.
    No changes are saved when the conversion is run in simulation mode.
    Only the first data record with the new key is saved. All others are
    discarded. These cannot be saved because the table key needs to be
    unique.

    How to fix this error?

    Check the data records to be discarded and, where applicable, change the
    fiscal year variant settings. If you already expected this kind of
    outcome from converting the fiscal year variants, execute the conversion
    in operational/update mode.

  • What is the cause and solution for SAP error message UGMD567 - Data loss in the records with the identical key &2 in table &1 ?

    The SAP error message UGMD567 indicates that there is data loss in records with identical keys in a specific table. This typically occurs when there are duplicate entries for a key that should be unique, leading to inconsistencies in the data.

    Cause:

    1. Duplicate Keys: The primary cause of this error is the presence of duplicate keys in the specified table. This can happen due to various reasons, such as:

      • Incorrect data entry or data import processes.
      • Issues during data migration or system upgrades.
      • Bugs in custom code or enhancements that manipulate data.
    2. Data Integrity Violations: The system expects unique keys for certain operations, and when it encounters duplicates, it cannot process the records correctly, leading to potential data loss.

    Solution:

    1. Identify Duplicates: Use SQL queries or SAP transaction codes (like SE16 or SE11) to identify the records with duplicate keys in the specified table. You can run a query to count occurrences of each key.

      Example SQL query:

      SELECT key_field, COUNT(*)
      FROM your_table
      GROUP BY key_field
      HAVING COUNT(*) > 1;
    2. Data Cleanup: Once you identify the duplicates, you need to decide how to handle them:

      • Delete Duplicates: If the duplicates are not needed, you can delete the extra records.
      • Merge Records: If the duplicates contain different information, you may need to merge the records into a single entry that retains all necessary data.
      • Correct Data Entry: Ensure that future data entries are validated to prevent duplicates.
    3. Implement Constraints: To prevent this issue from occurring in the future, consider implementing database constraints (like unique constraints) on the key fields of the table.

    4. Review Custom Code: If the issue is related to custom developments, review the code to ensure it handles data correctly and does not introduce duplicates.

    5. Consult SAP Notes: Check the SAP Support Portal for any relevant notes or patches that may address this issue, as there may be known bugs or fixes available.

    Related Information:

    • Transaction Codes: Use transaction codes like SE11 (Data Dictionary), SE16 (Data Browser), or SE80 (Object Navigator) to analyze the table structure and data.
    • Data Migration Tools: If the issue arose during data migration, review the tools and methods used to ensure they are configured correctly to handle unique keys.
    • SAP Community: Engage with the SAP Community forums for insights from other users who may have encountered similar issues.

    By following these steps, you should be able to resolve the UGMD567 error and prevent it from occurring in the future.
