  Cause:
  The error arises when:
  
  A user tries to rearrange or drop a column in the ALV grid that is not the first column (lead column).
  The ALV grid is configured in such a way that only the lead column can be dropped or rearranged.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Identify the Lead Column: Check which column is designated as the lead column in your ALV report. This is typically the first column displayed in the grid.
  
  
  Drop Only the Lead Column: If you need to drop a column, ensure that you are attempting to drop the lead column. You can usually do this by clicking on the header of the lead column and selecting the option to drop it.
  
  
  Modify ALV Configuration: If you need to allow dropping of other columns, you may need to modify the ALV configuration in your ABAP code. This may involve changing the settings in the REUSE_ALV_GRID_DISPLAY or CL_GUI_ALV_GRID methods to allow for more flexible column management.
  
  
  Check User Permissions: Ensure that the user has the necessary permissions to modify the ALV layout. Sometimes, restrictions can be set at the user level that prevent certain actions.
  
  
  Consult Documentation: If you are developing or maintaining the ALV report, refer to the SAP documentation for ALV grid controls to understand the limitations and capabilities regarding column management.
  
  
  Related Information:
  
  ALV Grid Control: The ALV grid control is a powerful tool in SAP for displaying and manipulating data in a tabular format. Understanding its properties and methods can help in customizing the behavior of the grid.
  SAP Notes: Check SAP Notes for any known issues or updates related to ALV grid functionality. Sometimes, specific versions of SAP may have bugs that are addressed in later patches.
  User Training: If users frequently encounter this error, consider providing training on how to use the ALV grid effectively, including how to manage columns.
