• What is the cause and solution for SAP error message SALV_WD_MSG603 - Displayed columns = 0 creates an empty table without visible columns ?

  The SAP error message SALV_WD_MSG603 indicates that the display columns for a table are set to zero, which results in an empty table without any visible columns. This typically occurs in the context of using the SAP ALV (ABAP List Viewer) or similar display components in Web Dynpro applications.
  Cause:
  
  No Columns Defined: The most common cause of this error is that no columns have been defined for the ALV grid or table. This can happen if the data source does not have any fields mapped to display or if the field definitions are missing.
  Incorrect Field Mapping: If the fields from the data source are not correctly mapped to the display columns, it can lead to a situation where the table has no visible columns.
  Dynamic Column Configuration: If the columns are being configured dynamically and the logic fails or does not execute as expected, it may result in zero columns being displayed.
  Authorization Issues: Sometimes, authorization issues can prevent certain fields from being displayed, leading to an empty table.
  
  Solution:
  
  Check Column Definitions: Ensure that the columns are properly defined in the ALV configuration. Verify that the field catalog is correctly set up and that the fields you want to display are included.
  Review Data Source: Make sure that the data source (internal table or database table) contains data and that the fields you want to display are populated.
  Debug Dynamic Logic: If the columns are being configured dynamically, debug the logic to ensure that it is executing correctly and that the expected columns are being added to the display.
  Authorization Check: Verify that the user has the necessary authorizations to view the fields in question. If certain fields are restricted, they may not appear in the display.
  Test with Static Configuration: As a troubleshooting step, try configuring the ALV with a static set of columns to see if they display correctly. This can help isolate whether the issue is with dynamic configuration or the data itself.
  
  Related Information:
  
  ALV Documentation: Review the SAP documentation on ALV and Web Dynpro for best practices on configuring display tables.
  SAP Notes: Check for any relevant SAP Notes that may address known issues or bugs related to the ALV display.
  Community Forums: Engage with SAP community forums or support channels for additional insights or similar experiences from other users.
  
  By following these steps, you should be able to identify the cause of the error and implement a solution to ensure that the table displays the desired columns correctly.
