*& 未完全 – v01 – 20081212 *
*& 未完全 – v02 – 20090731 *

*& ALV显示可以用的FM包括： *
*& 1、REUSE_ALV_GRID_DISPLAY *
*& 2、REUSE_ALV_GRID_DISPLAY_LVC *
*& 3、REUSE_ALV_BLOCK_LIST_DISPLAY *
*& *
*& ALV显示相关FM包括： *
*& 1、REUSE_ALV_FIELDCATALOG_MERGE – 制作 类型的 fieldcatalog *
*& 2、LVC_FIELDCATALOG_MERGE – 制作 LVC_T_FCAT 类型的 fieldcatalog *
*& 3、REUSE_ALV_BLOCK_LIST_INIT *

*& ALV(REUSE_ALV_GRID_DISPLAY)输出必须的内容： *
*& 1、output itab *
*& 2、fieldcatalog *
*&———————————————————————*
*& 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 *
