本文介绍了一种在 ABAP 环境中如何通过编程方式隐藏报表参数的方法。具体实现上，作者展示了如何在 ATSELECTION-SCREENOUTPUT 段落中通过检查屏幕名称来设置参数为不可见，并提供了具体的 ABAP 代码示例。
REPORT z_password.
PARAMETERS: p_pass TYPE xuncode.
*---------------------------------------------------------------------*
AT SELECTION-SCREEN OUTPUT.
LOOP AT SCREEN.
IF screen-name = 'P_PASS'.
screen-invisible = '1'.
MODIFY SCREEN.
ENDIF.
ENDLOOP.
*---------------------------------------------------------------------*
START-OF-SELECTION.
WRITE: / p_pass.
PARAMETERS: p_pass TYPE xuncode.
*---------------------------------------------------------------------*
AT SELECTION-SCREEN OUTPUT.
LOOP AT SCREEN.
IF screen-name = 'P_PASS'.
screen-invisible = '1'.
MODIFY SCREEN.
ENDIF.
ENDLOOP.
*---------------------------------------------------------------------*
START-OF-SELECTION.
WRITE: / p_pass.
