  The SAP error message /AIF/MES291 Raw structure &1 does not exist in class &2 (method &3) typically occurs in the context of the Application Interface Framework (AIF) when the system is unable to find a specified raw structure in the given class and method. This can happen for several reasons, and here are some potential causes, solutions, and related information:
  Causes:
  
  Missing Structure Definition: The raw structure specified in the error message may not be defined in the system. This could be due to a missing transport or an incomplete configuration.
  Incorrect Class or Method: The class or method referenced in the error message may not be correctly configured or may not correspond to the expected raw structure.
  Transport Issues: If the structure was recently transported from another system, there may have been issues during the transport process that caused the structure not to be created.
  Namespace Issues: If the structure is in a different namespace, it may not be accessible in the current context.
  
  Solutions:
  
  Check Structure Definition: Verify that the raw structure (&1) exists in the system. You can do this by navigating to the Data Dictionary (transaction SE11) and checking for the structure.
  Review Class and Method: Ensure that the class (&2) and method (&3) are correctly defined and that they reference the correct raw structure. You can check this in the AIF configuration.
  Transport Check: If the structure was recently transported, check the transport logs for any errors. You may need to re-transport the object or manually create it in the target system.
  Namespace Verification: Ensure that the structure is in the correct namespace and that there are no access issues. If necessary, adjust the namespace settings or create the structure in the appropriate namespace.
  Debugging: If the issue persists, consider debugging the AIF process to trace where the error occurs and gather more context about the failure.
  
  Related Information:
  
  Transaction Codes: Use transaction codes like SE11 (Data Dictionary), SE80 (Object Navigator), and AIF configuration transactions to investigate the issue.
  SAP Notes: Check for relevant SAP Notes that may address this specific error or provide additional troubleshooting steps.
