1、业务背景
业务在销售订单中，通过长文本描述，记录了一些生产备注信息，如生产标准、客户要求等等。要求开发一个报表，能够方便查看和导出长文本信息。
2、实现效果
由于ALV列表长文本显示不友好，且长度有限制，仅能显示128位，故考虑双击展示长文本详细内容，最终实现效果如下：

3.2、显示html
（1）方式一：ABAP对话框显示html（本例使用，查看不用授权）
FORM frm_double_click USING p_row TYPE salv_de_row
p_column TYPE salv_de_column.
DATA: lt_data TYPE TABLE OF zsmm114 WITH HEADER LINE.
READ TABLE gt_vbak_po INTO DATA(ls_wa) INDEX p_row."读当前行
