  • What is the cause and solution for SAP error message UCFE503 - InfoObject 0BCS_DECUM must be uniquely defined in the query ?

    The SAP error message UCFE503 indicates that the InfoObject 0BCS_DECUM must be uniquely defined in the query. This error typically arises in the context of SAP BW (Business Warehouse) or SAP BI (Business Intelligence) when creating or executing queries in the Query Designer or BEx Analyzer.

    Cause:

    The error occurs when the InfoObject 0BCS_DECUM (which is often used for document numbers or similar identifiers) is included in the query in a way that it is not uniquely defined. This can happen due to several reasons:

    1. Multiple Instances: The InfoObject is included multiple times in the query, either in the selection criteria or in the display columns.
    2. Ambiguous Definitions: The InfoObject is defined in a way that the system cannot determine which instance to use.
    3. Incorrect Joins: If the InfoObject is part of multiple data sources or joins, it may lead to ambiguity in the query.

    Solution:

    To resolve the UCFE503 error, you can take the following steps:

    1. Check Query Design:

      • Open the query in the Query Designer.
      • Ensure that the InfoObject 0BCS_DECUM is only included once in the query. Remove any duplicate instances.
    2. Review Filters and Variables:

      • Check if there are any filters or variables that might be causing ambiguity with the InfoObject. Ensure that they are correctly defined.
    3. Examine Data Sources:

      • If the query is based on multiple InfoProviders, ensure that the joins are correctly defined and that the InfoObject is not causing conflicts between different data sources.
    4. Use Unique Identifiers:

      • If necessary, consider using a different InfoObject or a unique identifier that can clearly distinguish the data being queried.
    5. Test the Query:

      • After making changes, test the query to ensure that it runs without errors.
    6. Consult Documentation:
