• What is the cause and solution for SAP error message EPM062 - No output structure could be determined for the ALV tree ?

  The SAP error message EPM062: No output structure could be determined for the ALV tree typically occurs when there is an issue with the configuration or definition of the ALV (ABAP List Viewer) tree structure in your ABAP program. This error indicates that the system is unable to determine the appropriate output structure for displaying data in the ALV tree format.
  Causes:
  
  Missing or Incorrect Output Structure: The output structure that is supposed to be used for the ALV tree is either not defined or incorrectly specified in the program.
  Data Retrieval Issues: The data retrieval logic may not be returning the expected data or structure, leading to the inability to map it to the ALV tree.
  Incorrect Field Catalog: The field catalog used for the ALV tree may not be properly defined or may not match the data being processed.
  Hierarchy Issues: If the ALV tree is expected to display hierarchical data, there may be issues with how the hierarchy is defined or structured in the data.
  
  Solutions:
  
  Check Output Structure: Ensure that the output structure for the ALV tree is correctly defined in your program. This includes checking the data types and ensuring that they match the expected structure.
  Define Field Catalog: Make sure that the field catalog is properly defined and includes all necessary fields that are to be displayed in the ALV tree.
  Review Data Retrieval Logic: Verify that the data retrieval logic (e.g., SELECT statements) is correctly fetching the data and that the data structure aligns with the expected output structure.
  Hierarchy Definition: If using hierarchical data, ensure that the hierarchy is correctly defined and that the data being passed to the ALV tree reflects this hierarchy.
  Debugging: Use debugging tools to step through the code and identify where the output structure is being determined. This can help pinpoint the exact location of the issue.
