*测试message。

parameters: p_budget type n,
p_area type c,
p_wemge type n.
SELECTION-SCREEN END OF BLOCK bk2.
IF p_budget IS NOT INITIAL.
MESSAGE I000(zfi01) WITH p_budget p_area p_wemge.
endif." ‘ I ’是类型;(zfi01)对应的是图1:message class;000 是对应的图2的message下的消息号:000;with 后的是三个变量,单价、面积、预算。
- 运行代码

- 弹出结果。因为类型 是‘I’,所以是弹出来的对话框,也可以设置为类型‘e’等。

PS: 不创建message ,直接运用message:

PS: 不创建message ,直接运用消息:
lMESSAGE 'Test message type I' TYPE 'I'.
结果:图5
PS:
所有的消息都存储在系统数据表T100中,包含四个字段,语言代码,消息类,消息序列号,消息文本。进入消息的初始界面的事务代码为SE91。消息类型(与消息类不同)共六种,A,E,I S,W,X。系统消息类为00。
例: MESSAGE S001(ZMM01) WITH 'Data was not found'."S是消息类型,001是消息文本,在此处为&占位符,所以需要WITH文本来替代,ZMM01是消息类。
