• What is the cause and solution for SAP error message SALV_X_API023 - Range table is not normalized ?

  The SAP error message SALV_X_API023: Range table is not normalized typically occurs when using the SAP ALV (ABAP List Viewer) framework, particularly when dealing with range tables in ABAP programs. This error indicates that the range table being passed to the ALV function is not in the expected normalized format.
  Cause:
  The error arises when the range table does not conform to the expected structure. In ABAP, a normalized range table should have the following characteristics:
  
  It should contain entries that are properly structured, meaning that each entry should have a SIGN, OPTION, LOW, and HIGH field.
  The entries should not have overlapping ranges or invalid combinations.
  
  Solution:
  To resolve the error, you can take the following steps:
  
  
  Check the Structure of the Range Table:
  Ensure that the range table you are passing to the ALV function is correctly defined. It should be of the type RANGE or a similar structure that includes the necessary fields.
  Example structure:
  TYPES: BEGIN OF ty_range,
           sign   TYPE c LENGTH 1,
           option TYPE c LENGTH 2,
           low    TYPE your_data_type,
           high   TYPE your_data_type,
         END OF ty_range.
  
  DATA: lt_range TYPE TABLE OF ty_range.
  
  
  Normalize the Range Table:
  If the range table contains overlapping or invalid entries, you need to normalize it. This can involve:
  
  Removing duplicates.
  Merging overlapping ranges.
  Ensuring that the SIGN and OPTION fields are set correctly.
  
  Example of normalizing:
  LOOP AT lt_range INTO DATA(range_entry).
    " Check and adjust the range entry as needed
  ENDLOOP.
  
  
  Use the Correct ALV Function:
  Make sure you are using the appropriate ALV function module or class method that expects a normalized range table. For example, if you are using CL_GUI_ALV_GRID, ensure that the parameters are correctly set.
  
  
  Debugging:
  If the issue persists, you can use debugging tools to inspect the contents of the range table just before it is passed to the ALV function. This will help you identify any anomalies in the data.
  
  
  Refer to Documentation:
  Check the SAP documentation for the specific ALV function you are using to ensure you are following the expected input structure.
  
  
  Related Information:
  
  ABAP Range Tables: Understanding how range tables work in ABAP is crucial. They are often used for selection criteria in database queries.
  ALV Documentation: Familiarize yourself with the ALV documentation provided by SAP, which includes examples and best practices for using ALV functions.
  SAP Community: If you are still facing issues, consider reaching out to the SAP Community or forums where other developers may have encountered similar issues.
  
  By following these steps, you should be able to resolve the SALV_X_API023 error and ensure that your range table is properly normalized for use with the ALV framework.
