Rule Definition
Exposing dynamic function calls through variables potentially allows the Risk of - Calling dangerous or unauthorized functions at runtime - Code Injection as Malicious users could inject names of dangerous function modules or execute unintended system functions leading to Potential for system manipulation or data corruption

Remediation
1- Maintain a strict whitelist of allowed function modules

Violation Code Sample

CALL FUNCTION p_name  " Security risk: Could call any function
   EXPORTING
      query_table          = 'YYYY'
   TABLES
      options              = lt_options
      fields               = lt_fields
      data                 = lt_t_data
   EXCEPTIONS
          OTHERS               = 1.

Fixed Code Sample

TRY.
      p_name = cl_abap_dyn_prg=>check_whitelist_str( val       = p_name
                                                     whitelist = 'XXXX' ).

      CALL FUNCTION p_name
        EXPORTING
          query_table          = 'YYYY'
        TABLES
          options              = lt_options
          fields               = lt_fields
          data                 = lt_t_data
        EXCEPTIONS
          OTHERS               = 1.
      IF sy-subrc <> 0.
* Implement suitable error handling here
      ENDIF.
    CATCH cx_abap_not_in_whitelist.
      MESSAGE 'Error Whitelist' TYPE 'E'.
  ENDTRY.
