ABAP函数调用SM30实现表视图维护

表维护除了调用ALV以外，还可以通过调用SM30的方式实现，以下为主要步骤

1.SE11将透明表设置为允许显示/维护。

2.SE37建立函数组，用于生成表维护代码可修改。

3.实用程序-表维护生成器。

注：权限组：&NC&

　　维护屏幕：单一；概述屏幕100

　　记录例程：不，或用户记录例程

4.调用SM30函数，添加选择屏幕条件

  DATA GT_DBA_SELLIST TYPE TABLE OF VIMSELLIST.
  DATA GT_TABNAME TYPE DD02V-TABNAME.

CALL FUNCTION 'VIEW_RANGETAB_TO_SELLIST' “添加选择屏幕条件
  EXPORTING
    FIELDNAME                = 'MATKL'
   APPEND_CONJUNCTION       = 'AND'
  TABLES
    SELLIST                  = GT_DBA_SELLIST
    RANGETAB                 = S_MATKL
          .


  CALL FUNCTION 'VIEW_MAINTENANCE_CALL' ” 调用SM30函数
    EXPORTING
      ACTION                               = 'U'
*     CORR_NUMBER                          = '          '
     GENERATE_MAINT_TOOL_IF_MISSING       = 'X'
*     SHOW_SELECTION_POPUP                 = ' '
      VIEW_NAME                            = 'ZTCS118'
     NO_WARNING_FOR_CLIENTINDEP           = 'X' “跳过警告弹窗

*     SUPPRESS_WA_POPUP                    = ' '
   TABLES
     DBA_SELLIST                          = GT_DBA_SELLIST
*     EXCL_CUA_FUNCT                       =
   EXCEPTIONS
     CLIENT_REFERENCE                     = 1
     FOREIGN_LOCK                         = 2
     INVALID_ACTION                       = 3
     NO_CLIENTINDEPENDENT_AUTH            = 4
     NO_DATABASE_FUNCTION                 = 5
     NO_EDITOR_FUNCTION                   = 6
     NO_SHOW_AUTH                         = 7
     NO_TVDIR_ENTRY                       = 8
     NO_UPD_AUTH                          = 9
     ONLY_SHOW_ALLOWED                    = 10
     SYSTEM_FAILURE                       = 11
     UNKNOWN_FIELD_IN_DBA_SELLIST         = 12
     VIEW_NOT_FOUND                       = 13
     MAINTENANCE_PROHIBITED               = 14
     OTHERS                               = 15
            .
  IF SY-SUBRC <> 0.
* Implement suitable error handling here
  ENDIF.

 5.SE54/SE55子例程，环境-修改-事件-05新条目控制（例：自动带出商品组描述）。

6.多表维护视图SE11/SE54创建并加入连接条件（未实现过）。
