  The SAP error message SALV_X_API106 indicates that a compound column in an ALV (ABAP List Viewer) grid requires at least two columns to be defined. This error typically occurs when you are trying to create a compound column but have not provided enough underlying columns to support it.
  Cause:
  The error arises when:
  
  You attempt to create a compound column in an ALV report but only specify one or no columns as part of that compound column.
  The definition of the compound column is incomplete or incorrect.
  
  Solution:
  To resolve this error, you need to ensure that you define at least two columns for the compound column. Here are the steps to do that:
  
  
  Check the Definition of the Compound Column:
  
  Ensure that you are adding at least two columns to the compound column definition.
  Review the code where you define the ALV layout and the compound column.

  DATA: lo_alv TYPE REF TO cl_salv_table,
        lo_columns TYPE REF TO cl_salv_columns_table,
        lo_column1 TYPE REF TO cl_salv_column,
        lo_column2 TYPE REF TO cl_salv_column,
        lo_compound_column TYPE REF TO cl_salv_column_compound.
  
  " Create ALV object
  cl_salv_table=>factory( IMPORTING r_salv_table = lo_alv
                          CHANGING  t_table      = it_data ).
  
  " Get columns
  lo_columns = lo_alv->get_columns( ).
  
  " Get individual columns
  lo_column1 = lo_columns->get_column( 'COLUMN1' ).
  lo_column2 = lo_columns->get_column( 'COLUMN2' ).
  
  " Create compound column
  lo_compound_column = lo_columns->add_compound_column( 'COMPOUND_COLUMN' ).
  lo_compound_column->add_column( lo_column1 ).
  lo_compound_column->add_column( lo_column2 ).
