  • What is the cause and solution for SAP error message SD_CDS_PROJECTION018 - Domain Values are not supported in Projection View Where-Condition ?

    The SAP error message SD_CDS_PROJECTION018 indicates that there is an issue with the use of domain values in a projection view's WHERE condition. This typically occurs in the context of Core Data Services (CDS) views in SAP, particularly when trying to filter data based on domain values that are not supported in the projection view.

    Cause:

    The error arises when you attempt to use a domain value in the WHERE clause of a projection view. Projection views are designed to provide a simplified view of data, and they have certain restrictions on the types of conditions that can be applied. Domain values, which are predefined values associated with a data element, may not be directly usable in this context.

    Solution:

    To resolve this error, consider the following approaches:

    1. Use Direct Values: Instead of using domain values, try to use the actual values that the domain represents. This means replacing the domain value with its corresponding literal value in the WHERE condition.

    2. Modify the CDS View: If you have control over the CDS view definition, you may need to adjust the WHERE condition to avoid using domain values. This could involve changing the logic to use different fields or conditions that are supported.

    3. Check for Compatibility: Ensure that the fields and values you are using in the WHERE clause are compatible with the projection view. Review the documentation for the specific projection view to understand its limitations.

    4. Consult SAP Notes: Sometimes, specific issues may be documented in SAP Notes. Check the SAP Support Portal for any relevant notes that might address this error or provide additional guidance.

    5. Testing: After making changes, test the projection view to ensure that it behaves as expected and that the error no longer occurs.

    Related Information:

    • CDS Views: Core Data Services (CDS) are a framework for defining semantically rich data models in SAP. Understanding how CDS views work and their limitations is crucial for troubleshooting issues like this.
    • Domain Values: In SAP, domain values are used to define a set of permissible values for a field. Familiarity with how domains are defined and used can help in understanding why certain values may not be supported in specific contexts.
    • SAP Documentation: Refer to the official SAP documentation for detailed information on CDS views, projection views, and the use of domain values.

    If the issue persists after trying the above solutions, consider reaching out to your SAP support team or consulting with an SAP expert for further assistance.
