  • What is the cause and solution for SAP error message /IWBEP/CM_V4_MED152 - Precision value invalid for property '&1' of entity type '&2' ?

    The SAP error message /IWBEP/CM_V4_MED152 indicates that there is an issue with the precision value for a property in an entity type when working with OData services in SAP Gateway. This error typically arises when the precision defined for a numeric property in the OData model does not match the expected format or is invalid.

    Cause:

    1. Invalid Precision Definition: The precision value defined for a numeric property in the OData model may be set incorrectly. For example, if the precision is defined as a negative number or exceeds the maximum allowed value.
    2. Mismatch with Database Definition: The precision defined in the OData service may not match the precision defined in the underlying database table or structure.
    3. Data Type Issues: The data type of the property may not support the specified precision, leading to this error.

    Solution:

    1. Check OData Model Definition:

      • Review the OData service definition in the SAP Gateway Service Builder (transaction code SEGW).
      • Ensure that the precision for the numeric property is defined correctly. The precision should be a non-negative integer and should not exceed the maximum allowed value for the data type.
    2. Verify Database Structure:

      • Check the underlying database table or structure to ensure that the precision defined in the OData model matches the precision defined in the database.
      • If there are discrepancies, adjust the OData model or the database structure accordingly.
    3. Adjust Data Types:

      • Ensure that the data type of the property in the OData model is appropriate for the precision being defined. For example, if you are using a decimal type, ensure that the precision and scale are set correctly.
    4. Regenerate the OData Service:

      • After making changes to the OData model or database structure, regenerate the OData service to ensure that the changes take effect. This can be done in the Service Builder by right-clicking on the service and selecting "Generate".
    5. Test the Service:

      • After making the necessary adjustments, test the OData service to ensure that the error is resolved and that the service behaves as expected.

    Related Information:

    • SAP Notes: Check for any relevant SAP Notes that may provide additional insights or fixes related to this error message.
    • OData Documentation: Review the official SAP documentation on OData services and data types to understand the requirements for precision and scale.
    • Debugging: If the issue persists, consider debugging the OData service to trace the exact point of failure and gather more information about the context of the error.
