*& ALV(REUSE_ALV_GRID_DISPLAY)输出必须的内容：                         *
*& 1、output itab                                                      *

*&                          相关FM注意事项                             *
*& 一、REUSE_ALV_FIELDCATALOG_MERGE                                    *
*& 1、I_INTERNAL_TABNAME所用的变量对应结构体必须用DATA+BEGIN申明，     *
*&    不可以使用DATA+TYPE line type，否则不会返回Fieldcatalog。        *
*& 2、修改了I_INTERNAL_TABNAME对应结构体后，                           *
*&    必须/N后重新进去SE38时，才会生效。                               *
*& 3、程序代码每行不能太长，不然容易报错，                             *
*&    具体内容见FORM f_fieldcatalog。                                  *
*&                                                                     *
*&                                                                     *
*& 二、REUSE_ALV_GRID_DISPLAY                                          *
*& 1、使用标准GUI：STANDARD_FULLSCREEN                                 *
*& 2、标准GUI中的&OLO中显示的列名取决于fieldcatalog中的设置            *
*&                                                                     *
*& 三、REUSE_ALV_BLOCK_LIST_DISPLAY                                    *
*& 1、首先用 REUSE_ALV_BLOCK_LIST_INIT 初始化                          *
*& 2、然后用 REUSE_ALV_BLOCK_LIST_APPEND 添加需要显示的ALV             *
*& 3、最后用 REUSE_ALV_BLOCK_LIST_DISPLAY 显示                         *
*&                                                                     *

*& 1、效果类似 WRITE … ROUND r
* WRITE … ROUND r 的效果
*
* Scaled output of a field of type P.
*
* The decimal point is first moved r places to the left (r > 0) or to
* theright (r < 0); this is the same as dividing with the appropriate
* exponent 10**r. The value determined in this way is output with the
* valid number of digits before and after the decimal point. If the
* decimal point is moved to the left, the number is rounded.
*
* For further information about the interaction between the formatting
* options CURRENCY and DECIMALS, see the notes below.
*
*Example
*Effect of different ROUND specifications:
*
*DATA: X TYPE P DECIMALS 2 VALUE ’12493.97′.
*
*WRITE: /X ROUND -2,   "output: 1,249,397.00
