Smart SAP Assistant

• What is the cause and solution for SAP error message SALV_X_API010 - The table row type is not structured ?

  The SAP error message SALV_X_API010: The table row type is not structured typically occurs when you are working with the SAP ALV (ABAP List Viewer) framework, particularly when using the SALV (Simple ALV) classes. This error indicates that the data you are trying to display in the ALV grid is not in the expected structured format.
  Cause:
  
  Non-Structured Data: The data you are trying to pass to the ALV is not in a structured format. ALV expects an internal table with a defined structure (i.e., a table type or a structure type).
  Incorrect Data Type: You might be passing a standard internal table or a simple data type instead of a structured internal table.
  Improper Declaration: The internal table or the structure you are using may not be properly declared or initialized.
  
  Solution:
  To resolve this error, you can follow these steps:
  
  
  Check Data Structure:
  
  Ensure that the internal table you are passing to the ALV is defined with a structured type. For example, you should have a structure defined using TYPES and then declare an internal table of that structure type.
  
  TYPES: BEGIN OF ty_data,
           field1 TYPE string,
           field2 TYPE i,
         END OF ty_data.
  
  DATA: it_data TYPE TABLE OF ty_data,
        wa_data TYPE ty_data.
  
  
  Populate the Internal Table:
  
  Make sure that you are populating the internal table with data that matches the structure you defined.
  
  wa_data-field1 = 'Example'.
  wa_data-field2 = 123.
  APPEND wa_data TO it_data.
  
  
  Pass the Correct Table to ALV:
  
  When you create the ALV object, ensure you are passing the structured internal table.
  
  DATA(lo_alv) = cl_salv_table=>factory( IMPORTING r_salv_table = lo_table
                                          CHANGING  t_table      = it_data ).
  
  
  Check for Empty or Uninitialized Tables:
  
  Ensure that the internal table is not empty or uninitialized when you pass it to the ALV.
  
  
  
  Debugging:
  
  If the issue persists, use debugging to check the type of the internal table and ensure it matches the expected structure.
  
  
  
  Related Information:
  
  SALV Classes: Familiarize yourself with the SALV classes and their methods. The main class is cl_salv_table, which is used to create and manipulate ALV grids.
  Documentation: Refer to the SAP documentation for ALV and SALV for more details on how to work with structured data.
  ABAP Data Types: Understanding ABAP data types and structures is crucial for working with ALV and avoiding such errors.
  
  By ensuring that you are using a properly structured internal table and following the guidelines above, you should be able to resolve the SALV_X_API010 error.
