  • What is the cause and solution for SAP error message UC002 - Sender structure &1 does not exist ?

    The SAP error message UC002, which states "Sender structure &1 does not exist," typically occurs in the context of data transfer or integration processes, particularly when dealing with IDocs, BAPIs, or other data exchange mechanisms. This error indicates that the system is unable to find the specified sender structure, which is necessary for processing the data.

    Cause:

    1. Missing Structure Definition: The sender structure (indicated by &1) has not been defined in the system. This could be due to a missing configuration or an incomplete implementation.
    2. Incorrect Configuration: The configuration settings for the data transfer might be incorrect, leading the system to look for a structure that does not exist.
    3. Transport Issues: If the structure was recently transported from another system, the transport might not have included the necessary definitions or might have failed.
    4. Namespace Issues: The structure might exist in a different namespace or client, leading to the error when the system tries to access it.

    Solution:

    1. Check Structure Definition: Verify that the sender structure exists in the system. You can do this by navigating to the relevant transaction (e.g., SE11 for Data Dictionary) and checking if the structure is defined.
    2. Review Configuration: Ensure that the configuration for the data transfer process is correct. This includes checking any relevant settings in transaction codes like WE20 (for IDoc partner profiles) or other related configuration transactions.
    3. Transport Check: If the structure was supposed to be transported, check the transport logs to ensure that it was successfully imported into the target system.
    4. Namespace Verification: Make sure that you are referencing the correct namespace. If the structure is part of a custom development, ensure that it is correctly defined in the appropriate namespace.
    5. Consult Documentation: If the structure is part of a standard SAP module or third-party add-on, consult the relevant documentation to ensure that all necessary components are installed and configured.

    Related Information:

    • Transaction Codes: SE11 (Data Dictionary), SE80 (Object Navigator), WE20 (Partner Profiles), WE21 (Port Definition).
    • SAP Notes: Check SAP Notes for any known issues or patches related to the specific structure or data transfer process you are working with.
    • Debugging: If you have access to debugging tools, you can set breakpoints in the relevant ABAP code to trace where the error is being triggered and gather more context about the issue.

    If the problem persists after checking these areas, it may be beneficial to reach out to your SAP Basis or development team for further assistance.
