ABAP之程序相互调用--SUBMIT

功能代码的重用是个老生常谈的话题，ABAP代码中实现程序的调用以及调用时数据参数的传递又是怎样的呢

（1） 调用其他程序：

   * Trigger the IDOC
  SUBMIT zpcppmd001_idoc AND RETURN.

（2） 调用其他程序参数传递参数：

 当被调用的程序的屏幕有输入参数时：

       SUBMIT zreportwith p_param1 = 'value1'
                              with p_param2 = 'value2'.

当要传递一个内表到被调用的程序时,需要用SAP MEMORY或者ABAP MEMORY:

在调用的程序中：EXPORT it_tab TO MEMORY 'Z_MEMORY'.

在被调用的程序中：IMPORT T_ITABFROMMEMORY 'Z_MEMORY'.

 (3) 更复杂一点的可以用文件临时存储数据：

 带select-options程序的Submit的用法

*Code used to populate 'select-options' & execute report
DATA: seltab type table of rsparams,
      seltab_wa like line of seltab.

  seltab_wa-selname = 'PNPPERNR'.
  seltab_wa-sign    = 'I'.
  seltab_wa-option  = 'EQ'.

* load each personnel number accessed from the structure into
* parameters to be used in the report
  loop at pnppernr.
    seltab_wa-low = pnppernr-low.
    append seltab_wa to seltab.
  endloop.
  SUBMIT zreport with selection-table seltab
                                via selection-screen.

 

其他情况

*Submit report and return to current program afterwards

SUBMIT zreport AND RETURN.

*Submit report via its own selection screen

SUBMIT zreport VIA SELECTION-SCREEN.

*Submit report using selection screen variant

SUBMIT zreport USING SELECTION-SET 'VARIANT1'.
