• What is the cause and solution for SAP error message SALV_IDA100 - Field &: sorting is on raw-data but would require conversion ?

  The SAP error message SALV_IDA100 indicates that there is an issue with sorting data in an ALV (ABAP List Viewer) grid when the data is in raw format but requires conversion for sorting. This typically occurs when the data type of the field being sorted does not match the expected format for sorting operations.
  Cause:
  
  Data Type Mismatch: The field you are trying to sort is in a raw format (e.g., a string or binary format) that cannot be sorted directly without conversion to a more appropriate type (e.g., numeric or date).
  Field Definition: The field may not be defined correctly in the data structure or the ALV grid configuration, leading to issues when attempting to sort.
  Data Source: The data source may be providing raw data that is not suitable for sorting without transformation.
  
  Solution:
  
  
  Convert Data Type: Ensure that the data type of the field is appropriate for sorting. You may need to convert the raw data into a sortable format before passing it to the ALV grid. This can be done using ABAP functions or methods to convert the data type.
  
  For example, if the field is a string that represents a date, convert it to a date type before sorting.
  
  DATA: lv_date TYPE d.
  lv_date = CONVERT_DATE_STRING_TO_DATE( raw_date_string ).
  
  
  Adjust ALV Configuration: Check the ALV configuration to ensure that the field is defined correctly. Make sure that the field's data type in the ALV field catalog matches the actual data type of the data being displayed.
  DATA: lt_fieldcat TYPE lvc_t_fcat.
  CLEAR lt_fieldcat.
  APPEND VALUE #( fieldname = 'YOUR_FIELD' datatype = 'DATS' ) TO lt_fieldcat.
  
  
  Use a Sortable Field: If possible, use a different field that is already in a sortable format for sorting operations.
  
  
  Debugging: If the issue persists, use debugging tools to trace the data flow and identify where the conversion is failing. Check the data being passed to the ALV and ensure it is in the expected format.
  
  
  Related Information:
  
  ALV Grid Control: Understand how the ALV grid control works and how to configure it properly for sorting and displaying data.
  Data Conversion Functions: Familiarize yourself with ABAP data conversion functions that can help convert raw data into a suitable format for sorting.
  SAP Notes: Check SAP Notes for any known issues or patches related to the SALV_IDA100 error message, as there may be specific fixes or recommendations provided by SAP.
  
  By addressing the data type and ensuring proper configuration, you should be able to resolve the SALV_IDA100 error and enable sorting in your ALV grid.
