一 背景说明

实现效果：

二 实现步骤

2.1 创建屏幕

屏幕显示的字段准备 --> 屏幕绘制（字段元素类型的使用）--> 逻辑流程（PBO PAI）PBO:状态栏；PAI ：字段栏位的控制，ON REQUEST / ON INPUT ，值改变的时候触发/不为空，触发，MODULE函数。屏幕按钮事件，user_command，处理点击屏幕按钮之后所触发的逻辑

2.2 调用屏幕

CALL  SCREEN 9100 STARTING AT 10 5 ENDING AT 200 30.

2.3 代码分布

2.3.1，主程序，2.3.2，逻辑流程，MODULE函数，user_command，status ；基本上有5处代码

2.4 创建屏幕步骤细节

2.4.1 创建屏幕

2.4.2 输出屏幕编号 

 

2.4.3 屏幕：属性、元素单元、逻辑流

 屏幕的三大部分细节

2.4.4 逻辑流

逻辑流程中有两个部分的信息，PBO、PAI

PROCESS BEFORE OUTPUT.
* MODULE STATUS_9100.
*
PROCESS AFTER INPUT.
* MODULE USER_COMMAND_9100. 

 2.4.5 屏幕绘制，进入屏幕布局

 2.4.6 从元素库中拖动元素到面板上

2.4.7 从元素库中拖动表格向导到面板上 （表格向导有6个步骤）

 

 2.4.8 创建状态栏、创建按钮事件

 创建成功之后分别对应到PBO PAI的模块中

 2.4.9  状态栏中的按钮在屏幕中的位置

 2.4.10 按钮事件编码区域

在这个区域，可以对屏幕的表，输入框里的值进行操作等等

2.4.11 PAI中添加MODEULE

屏幕逻辑流的关于 MODULE，

FIELD ls_head-vkorg MODULE check_vkorg ON REQUEST." 值改变，触发
FIELD ls_head-vkorg MODULE check_vkorg ON INPUT.       " 不为空，触发

 这个区域可以写搜索帮助等

 2.4.12 屏幕属性设置成对话框方式

屏幕需要选择对话框的方式

2.4.13 元素类型说明

 

 字段的输入、输出、必填控制，如果是按钮元素，请输入功能码

2.5 代码分布细节
