1、业务需求

针对用户使用销售订单时，判断是否有权限，没有权限时隐藏销售订单抬头和行项目的价格相关字段

2、增强实现

2.1、隐藏抬头和行项目价格

隐藏抬头和行项目表格中的净值和净价字段

在程序MV45AFZZ→USEREXIT_FIELD_MODIFICATION中写隐式增强

"--------------------@斌将军--------------------
FORM USEREXIT_FIELD_MODIFICATION.

* CASE SCREEN-GROUP3.
*   WHEN '900'.
*     IF VBAK-VBTYP NE IF_SD_DOC_CATEGORY=>INQUIRY.
*       SCREEN-ACTIVE = 0.
*     ENDIF.
* ENDCASE.

* CASE SCREEN-NAME.
*   WHEN 'VBAK-VBELN'.
*     SCREEN-ACTIVE = 0.
* ENDCASE.

"""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""$"$\SE:(1)
*$*$-Start: (1)---------------------------------------------------------------------------------$*$*
ENHANCEMENT 1  ZSD_VA01_PRICE.    "active version

  IF sy-tcode = 'VA01' OR sy-tcode = 'VA02' OR sy-tcode = 'VA03' OR sy-tcode = 'VA05'.

    IF (
       screen-name = 'VBAK-NETWR' OR  "抬头 净值
       screen-name = 'VBAK-WAERK' OR  "抬头 货币
*     screen-name = 'RV45A-KOEIN' OR "项目 货币
       screen-name = 'VBAP-NETPR' OR  "项目 净价
       screen-name = 'VBAP-NETWR' "OR  "项目 净值
*     screen-name = 'VBAP-WAERK' OR  "项目 SD 凭证货币
        ).
      AUTHORITY-CHECK OBJECT 'ZCONDMANT'
      ID 'ZCHECK' FIELD 'M'.
      IF sy-subrc <> 0."没有权限
        screen-active = 0.
        MODIFY SCREEN.
      ENDIF.
    ENDIF.
  ENDIF.
ENDENHANCEMENT.
*$*$-End:   (1)---------------------------------------------------------------------------------$*$*
ENDFORM.
"--------------------@斌将军--------------------

效果如下

2.2、隐藏条件页签价格

还需要隐藏抬头和行项目的条件页签中的价格数据

在程序LV69AF01→TCTRL_KONDITIONEN_INIT中写隐式增强。

此处的隐式增强必须写在FORM的末尾隐式增强点处，不能写在FORM开头的隐式增强点处。

因为抬头和行项目的条件页签都是调用了这段相同的代码，在第一次进入会对tctrl_konditionen进行重置，导致增强代码不起作用，所以要将增强代码写在FORM末尾

参考代码

"--------------------@斌将军--------------------
FORM tctrl_konditionen_init.
  DATA: da_tfill LIKE sy-tabix.

* Refresh table control if screen number has changed
  STATICS: last_dynnr TYPE dynnr.
  IF sy-dynnr NE last_dynnr AND gf_called_by_lord IS INITIAL.
    last_dynnr = sy-dynnr.
    REFRESH CONTROL 'tctrl_konditionen' FROM SCREEN sy-dynnr.
  ENDIF.

  DESCRIBE TABLE xkomv LINES da_tfill.

    AUTHORITY-CHECK OBJECT 'ZCONDMANT'
     ID 'ZCHECK' FIELD 'M'.
    IF sy-subrc <> 0."没有权限

    "隐藏净值、税收字段
      LOOP AT SCREEN.
        IF screen-name = 'KOMP-NETWR' OR screen-name = 'KOMP-MWSBP'.
          screen-active = 0.
          MODIFY SCREEN.
        ENDIF.
      ENDLOOP.
      
      "隐藏表格中金额、定价值字段
      LOOP AT tctrl_konditionen-cols INTO DATA(lv_acol).
        IF lv_acol-screen-name EQ 'KOMV-KBETR' OR lv_acol-screen-name EQ 'KOMV-KWERT'.
          lv_acol-invisible = 1.
          MODIFY tctrl_konditionen-cols FROM lv_acol INDEX sy-tabix.
        ENDIF.
      ENDLOOP.
    ENDIF.

  ENDIF.
ENDENHANCEMENT.
*$*$-End:   (1)---------------------------------------------------------------------------------$*$*
ENDFORM.                    "tctrl_konditionen_init

效果如下
