  • What is the cause and solution for SAP error message SMT_CONFIG102 - Source structure is not specified ?

    The SAP error message SMT_CONFIG102: Source structure is not specified typically occurs in the context of SAP's System Landscape Transformation (SLT) or when configuring data replication settings. This error indicates that the source structure for the data replication process has not been defined or is missing in the configuration.

    Cause:

    1. Missing Source Structure: The source structure (which defines the data model of the source system) has not been specified in the configuration settings.
    2. Incorrect Configuration: There may be an issue with the configuration of the SLT system, where the source structure is not properly linked to the target structure.
    3. Transport Issues: If the configuration was transported from one system to another, the source structure may not have been included or properly set up in the target system.

    Solution:

    1. Define Source Structure:

      • Go to the SLT configuration transaction (usually LTRC).
      • Check the configuration settings for the relevant replication setup.
      • Ensure that the source structure is defined correctly. This may involve specifying the source table or view that you want to replicate.
    2. Check Configuration:

      • Verify that the source and target systems are correctly configured and that the necessary connections are established.
      • Ensure that the source structure is correctly mapped to the target structure in the SLT configuration.
    3. Reconfigure if Necessary:

      • If the source structure is missing, you may need to reconfigure the replication setup. This can involve deleting the existing configuration and creating a new one with the correct source structure.
    4. Transport Issues:

      • If the configuration was transported, ensure that all necessary objects, including the source structure, were included in the transport request.
      • Check the transport logs for any errors or warnings that might indicate missing components.
    5. Consult Documentation:

      • Refer to SAP documentation or help resources for specific guidance on configuring SLT and resolving related errors.

    Related Information:

    • Transaction Codes: Common transaction codes related to SLT include LTRC (SLT Configuration), LTMOM (Modeling), and LTMC (Migration Cockpit).
    • SAP Notes: Check SAP Notes for any known issues or patches related to the error message SMT_CONFIG102.
    • SLT Documentation: Review the official SAP documentation for System Landscape Transformation for detailed configuration steps and troubleshooting tips.

    If the issue persists after following these steps, consider reaching out to SAP support or consulting with an SAP expert for further assistance.
