*& 一、REUSE_ALV_FIELDCATALOG_MERGE??????????????????????????????????? *
*& 1、I_INTERNAL_TABNAME所用的變量對應(yīng)結(jié)構(gòu)體必須用DATA+BEGIN申明，???? *
*&??? 不可以使用DATA+TYPE line type，否則不會返回Fieldcatalog。??????? *
*& 2、修改了I_INTERNAL_TABNAME對應(yīng)結(jié)構(gòu)體后，?????????????????????????? *
*&??? 必須/N后重新進去SE38時，才會生效。?????????????????????????????? *
*& 3、程序代碼每行不能太長，不然容易報錯，???????????????????????????? *
*&??? 具體內(nèi)容見FORM f_fieldcatalog。????????????????????????????????? *
*&???????????????????????????????????????????????????????????????????? *
*&???????????????????????????????????????????????????????????????????? *
*& 二、REUSE_ALV_GRID_DISPLAY????????????????????????????????????????? *
*& 1、使用標(biāo)準(zhǔn)GUI：STANDARD_FULLSCREEN???????????????????????????????? *
*& 2、標(biāo)準(zhǔn)GUI中的&OLO中顯示的列名取決于fieldcatalog中的設(shè)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 添加需要顯示的ALV???????????? *

*& 1、效果類似 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

*?????? /X ROUND? 5,?? "output:???????? 0.12
*
