ABAP Call Transaction功能大全

在ABAP程序中，可以使用CALL TRANSACTION语句调用其他事务代码。这种方式可以用于启动SAP中的标准或自定义事务代码。

以下是一些使用CALL TRANSACTION的常见方法：

1. 直接调用事务代码：

CALL TRANSACTION 'FB01'.

2. 使用参数传递：

DATA: BEGIN OF it_selection,
        vbeln TYPE vbak-vbeln,
      END OF it_selection.
 
it_selection-vbeln = '0016410006'.
 
CALL TRANSACTION 'VL02N' USING it_selection.

3. 使用选择屏幕参数：

DATA: it_selection_parameter TYPE TABLE OF bapiparms,
      wa_selection_parameter LIKE LINE OF it_selection_parameter.
 
wa_selection_parameter-selname = 'VBAK-VBELN'.
wa_selection_parameter-sign = 'I'.
wa_selection_parameter-option = 'EQ'.
wa_selection_parameter-low = '0016410006'.
APPEND wa_selection_parameter TO it_selection_parameter.
 
CALL TRANSACTION 'VL02N' PARAMETERS FROM it_selection_parameter.

4. 使用选择屏幕参数并带有回调函数：

DATA: it_selection_parameter TYPE TABLE OF bapiparms,
      wa_selection_parameter LIKE LINE OF it_selection_parameter.
 
wa_selection_parameter-selname = 'VBAK-VBELN'.
wa_selection_parameter-sign = 'I'.
wa_selection_parameter-option = 'EQ'.
wa_selection_parameter-low = '0016410006'.
APPEND wa_selection_parameter TO it_selection_parameter.
 
CALL TRANSACTION 'VL02N' 
  PARAMETERS FROM it_selection_parameter 
  MODE 'E' 
  UPDATE 'S'.

5. 使用回调函数并获取返回的数据：

DATA: it_selection_parameter TYPE TABLE OF bapiparms,
      wa_selection_parameter LIKE LINE OF it_selection_parameter.
 
wa_selection_parameter-selname = 'VBAK-VBELN'.
wa_selection_parameter-sign = 'I'.
wa_selection_parameter-option = 'EQ'.
wa_selection_parameter-low = '0016410006'.
APPEND wa_selection_parameter TO it_selection_parameter.
 
DATA: it_return TYPE TABLE OF bapiret2.
 
CALL TRANSACTION 'VL02N' 
  PARAMETERS FROM it_selection_parameter 
  MODE 'E' 
  UPDATE 'S' 
  USING it_return.

6. 使用回调函数并获取返回的数据，并进行处理：

DATA: it_selection_parameter TYPE TABLE OF bapiparms,
      wa_selection_parameter LIKE LINE OF it_selection_parameter.
 
wa_selection_parameter-selname = 'VBAK-VBELN'.
wa_selection_parameter-sign = 'I'.
wa_selection_parameter-option = 'EQ'.
wa_selection_parameter-low = '0016410006'.
APPEND wa_select
