  The SAP error message SALV_WD_MSG604 indicates that the display of rows in a table is zero, resulting in an empty table without any visible rows. This issue typically arises in the context of SAP Web Dynpro applications, particularly when using the ALV (ABAP List Viewer) component.
  Causes:
  
  No Data Returned: The most common cause is that the underlying data source (e.g., database table or internal table) does not contain any records that meet the selection criteria.
  Filter Conditions: There may be filter conditions applied that restrict the data being displayed, leading to zero rows being returned.
  Authorization Issues: The user may not have the necessary authorizations to view the data, resulting in an empty output.
  Incorrect Data Binding: The data binding between the data source and the ALV table may not be set up correctly, leading to no data being displayed.
  Errors in Data Retrieval Logic: There may be issues in the ABAP code that retrieves data, such as incorrect SQL queries or logic errors.

  Debugging: Use the ABAP debugger to step through the code that retrieves and binds the data to the ALV. Check for any logical errors or issues in data retrieval.
  Data Binding: Ensure that the data binding between the data source and the ALV is correctly configured. Check the properties of the ALV component to ensure it is pointing to the correct data structure.
