    The SAP error message WXCM028 Structure: &1 typically appears in the context of SAP Web Dynpro or ABAP programming when there is an issue related to a structure. The message text usually indicates a problem with a structure, but the exact cause depends on the context in which it appears.


    Error Message Details

    • Message ID: WXCM
    • Message Number: 028
    • Message Text: Structure: &1

    The placeholder &1 is replaced by the name of the structure involved.


    Common Cause

    This error often occurs when:

    • There is a mismatch or inconsistency in the structure definition used in the Web Dynpro component or ABAP program.
    • The structure referenced in the code or metadata does not exist or is not properly defined.
    • The structure is expected but missing in the context (e.g., in context mapping, interface definition, or data binding).
    • The structure is used incorrectly in the Web Dynpro context node or attribute.

    Typical Scenarios

    1. Web Dynpro Context Issues:

      • The context node or attribute is defined with a structure that is not available or incorrectly referenced.
      • The structure is changed in the ABAP Dictionary but not updated in the Web Dynpro component.
    2. Interface or Method Parameter Mismatch:

      • A method or interface expects a structure parameter that is not correctly declared or passed.
    3. Metadata or Data Binding Problems:

      • The structure used in data binding or UI element binding is inconsistent or missing.

    Solution Steps

    1. Check the Structure Definition:

      • Verify that the structure named in the error message exists in the ABAP Dictionary (transaction SE11).
      • Ensure the structure is active and correctly defined.
    2. Update Web Dynpro Component:

      • If the structure was changed recently, refresh or re-import the structure in the Web Dynpro component.
      • Go to the context tab in the Web Dynpro component and check the context nodes and attributes.
      • Re-bind or re-map the context nodes if necessary.
    3. Check Interface and Method Signatures:

      • Verify that the method parameters or interface definitions using the structure are consistent.
      • Make sure the structure is correctly referenced in the method signature.
    4. Regenerate or Rebuild:

      • Sometimes, regenerating the Web Dynpro component or recompiling the program can resolve inconsistencies.
    5. Check for Transport or Version Issues:

      • If the structure was transported from another system, ensure the transport was successful and the structure is available in the target system.

    Additional Information

    • Transaction SE11: Use to check and maintain the structure.
    • Web Dynpro Explorer: Use to check context nodes and attributes.
    • ABAP Editor (SE38/SE80): Use to check the code referencing the structure.
    • SAP Notes: Search for WXCM028 in SAP Support Portal for any specific notes or patches.

    Summary

    Aspect Details
    Cause Structure referenced in Web Dynpro or ABAP code is missing, inconsistent, or incorrectly defined.
    Solution Verify and correct the structure definition, update Web Dynpro context, check method signatures, and recompile.
