ON CHANGE OF 的使用方法
时间: 2024-01-30 12:11:42 浏览: 21
ON CHANGE OF 是一个在VBA中用于监控特定单元格或单元格范围的事件。当单元格的值发生改变时,会触发ON CHANGE OF事件,并执行相应的VBA代码。以下是使用ON CHANGE OF的基本步骤:
1. 在VBA中打开工作表或模块。
2. 选择“工具”菜单中的“宏”选项。
3. 点击“新建”,创建一个新的宏。
4. 在代码编辑器中输入以下代码:
```VBA
Private Sub Worksheet_Change(ByVal Target As Range)
'Code to be executed on change of target cell(s)
End Sub
```
5. 在代码中添加你想要执行的特定操作。例如,你可以使用IF语句检查目标单元格的值是否符合你的条件,如果符合条件,则执行特定操作。
需要注意的是,ON CHANGE OF事件只能在工作表模块中使用,而不能在标准模块中使用。

ABAP ON CHANG OF
ABAP中的 ON CHANGE OF 用于监测内部表数据的变化。当内部表中的数据发生变化时,ON CHANGE OF事件会被触发,从而执行相应的ABAP代码。以下是使用ON CHANGE OF的基本步骤:
1. 声明内部表和数据类型
```ABAP
TYPES: BEGIN OF ty_data,
field1 TYPE char10,
field2 TYPE char20,
END OF ty_data.
DATA: itab TYPE STANDARD TABLE OF ty_data WITH NON-UNIQUE KEY field1.
```
2. 在内部表数据中添加ON CHANGE OF语句
```ABAP
LOOP AT itab ASSIGNING FIELD-SYMBOL(<fs_data>).
AT FIRST OR <fs_data>-field1 NE <fs_data>-field1.
"Code to be executed on change of field1
ENDAT.
AT FIRST OR <fs_data>-field2 NE <fs_data>-field2.
"Code to be executed on change of field2
ENDAT.
ENDLOOP.
```
需要注意的是,ON CHANGE OF只能在内部表循环中使用,而不能在单独的代码块中使用。此外,ON CHANGE OF事件只能检测内部表中的数据变化,而不能监控数据库表的变化。
sap abap function I_CHANGE_STATUS 的使用方法
"SAP ABAP function I_CHANGE_STATUS" is used to change the status of an object in the SAP system. Here are the steps to use this function:
1. First, you need to create an instance of the I_CHANGE_STATUS function module by using the CREATE_OBJECT statement.
2. Then, you need to set the relevant parameters for the function module. The main parameters are:
- OBJTYPE: The type of the object whose status you want to change (for example, BUS1001 for a business partner).
- OBJKEY: The key of the object whose status you want to change (for example, the business partner number).
- NEWSTATUS: The new status you want to set for the object.
3. Finally, you need to call the function module by using the CALL_METHOD statement.
Here is an example code snippet that demonstrates the usage of I_CHANGE_STATUS function module:
```
DATA: lo_object TYPE REF TO cl_swf_cnt,
lo_change_status TYPE REF TO object.
CREATE OBJECT lo_object
EXPORTING
object_type = 'BUS1001'
object_key = '123456'.
lo_change_status = lo_object->get_status_changer( ).
lo_change_status->objtype = 'BUS1001'.
lo_change_status->objkey = '123456'.
lo_change_status->newstatus = 'Z001'.
CALL METHOD lo_change_status->i_change_status.
```
In this example, we are changing the status of a business partner with a key of '123456' to status 'Z001'. You will need to adjust the values of the parameters based on your specific use case.
