  • What is the cause and solution for SAP error message UA_SM1028 - Formula for type &1/column &2 for time &3 already exists ?

    The SAP error message UA_SM1028 indicates that there is a conflict with a formula definition in the system. Specifically, it means that a formula for a certain type (indicated by &1), a specific column (indicated by &2), and a particular time (indicated by &3) already exists in the system. This typically occurs in the context of SAP's time management or payroll modules, where formulas are used to calculate various metrics.

    Cause:

    1. Duplicate Formula Definition: The most common cause of this error is that a formula with the same parameters (type, column, and time) has already been defined in the system. This can happen if a user attempts to create a new formula without checking for existing definitions.
    2. Configuration Issues: There may be issues in the configuration settings that allow for duplicate entries or improper handling of formula definitions.
    3. Data Migration: If data has been migrated from another system or if there have been recent changes to the configuration, it may lead to conflicts with existing formulas.

    Solution:

    1. Check Existing Formulas: Before creating a new formula, check the existing formulas in the system for the same type, column, and time. You can do this by navigating to the relevant configuration area in SAP.
    2. Modify Existing Formula: If a formula already exists and you need to make changes, consider modifying the existing formula instead of creating a new one.
    3. Delete Duplicate: If the existing formula is no longer needed, you can delete it to resolve the conflict.
    4. Consult Documentation: Review SAP documentation or help resources for guidance on managing formulas and understanding the specific context of the error.
    5. Contact SAP Support: If you are unable to resolve the issue, consider reaching out to SAP support for assistance, especially if this is a recurring problem.

    Related Information:

    • Transaction Codes: Familiarize yourself with relevant transaction codes that may help you navigate to the formula management area, such as PE02 (for maintaining payroll schemas) or PC00_MXX_CALC (for payroll calculation).
    • Authorization: Ensure that you have the necessary authorizations to view and modify formulas in the system.
    • Testing: After making changes, conduct thorough testing to ensure that the formulas are functioning as expected and that there are no further conflicts.

    By following these steps, you should be able to address the UA_SM1028 error effectively.
