SAP消息也是這樣,你可將所有能忽略的消息ignore讓它鞠躬盡瘁死而后已為你工作.

從是否允許你configure層次分兩種: configurable和non-configurable.
對configurable message可選的message type通常有S, I, W, E, A，
?I:信息窗口
?W:警告
E:錯誤
S:成功
A:終止程序

(online表示即時output message -表示switch off message繼續做后面工作 batchi表示做batch input時).
就是說對configurable message SAP允許你設置它是Error, warning或者switch off干脆忽略,通常這些個
錯誤不至于引起致命的系統邏輯錯誤.


一.基本概念
你可簡單理解為消息是SAP為exception預警的一種手段.
Application area:告訴你消息歸屬,分類吧.其實就是SE91所說的Message class

二:消息相關最常用的table:

????1. T100U 通過 T100U可以查看所有系統及用戶定義的消息,包括消息的一些更改情況可在該表中查尋

????2. T100 SAP能用到的消息

????3. T160M MM模塊相關消息表，此表可直接維護.可使用SE16對其進行維護。

????4. T100C 你定義的message通常將出現在此表， FI模塊中用戶自定義的消息，比如使用OBA5,OFMG等自定義的消息會寫入此表，CO配置消息不在此表

????5. T100S: 此表保存著允許用戶更改的應用區域和消息號,舉例假設你刪除了KI 005則在OBA5中再不能配置此消息.(對MM模塊有些例外,M7不在此表,使用OMCQ依舊可設置,M3不在此表,OMT4依舊可設置)

????此表也可直接維護.和T160M不同的是,你必須在SE16輸入T100S按新建按鈕才可維護.查詢時只可Display.

????6. T100W: For Workflow
????7、TVGMS: View Control
????8、T100S: Configurable system messages 顧名思義就是你能設置的消息.
比如OBA5你想設置F5 060消息,這個是FB50在balance<>0你想強行save彈出的,在T100s，中你將看到F5 060不在其中,因為這是將影響財務的致命錯誤,當然OBA5是不允許你去設置的.
**欺騙SAP使用OBA5強行Switch off F5 060.
????9、T100U: 最后更改消息的user table
???10、T5CBN: PC Operation Conditions


三.建立查詢消息.
T-code:SE91??消息維護
你可為自己的程序和Enhancement編寫消息.
通常在程序中你能看到類似.
?CALL FUNCTION 'READ_CUSTOMIZED_MESSAGE'
????EXPORTING
??????i_arbgb = i_arbgb
??????i_dtype = i_dtype
??????i_msgnr = i_msgnr
????IMPORTING
??????e_msgty = l_msgts.

??IF l_msgts NE '-'.(如果沒switch off)
然后就是提示. 然后去讀T100C 用戶自定的messge type(Error,warnig, error0決定是否繼續work.


四.設置消息(這個應該對大家有點用處)

相關T-code:(**很多是雷同的)
FI 部分:
OBA5:FI messge
BD60:Additional data for message type
OFMG:FOr FM Message
O04C:PI: Message Control Purchasing
OFPM:Change Message Control
OMPJ:Reqmts Type Message Control
F00-->***這個是send office message
KD99:setup message
KDNN:Setup messaeg

MM-PUR部分:
O04C:For purchase
OKZZ: Invoice Verification/Valuation
OMRM：Invoice Verification 發票校驗
OMT4：更改試圖，系統消息，物料主數據，
OMCQ：更改試圖，系統消息，庫存管理、產品日期，有效期，批號（M7?Inventory Management and Physical Inventory；MIGO?Inventory Management: Interface；OM?Customizing: Materials Management；12?Production date/shelf life expiration date/batches）

CO部分:
OPR4_ACT Multilevel Actual Settlement?
OPR4_CK Material Cost Estimate?
OPR4_CKML Closing and Calc. of Periodic Price?
OPR4_CKPF Price Update?
OPR4_KKA WIP Calculation?

SD部分"
OVAH :SD Define Variable Messages
Others:
OPR5：
OPR1：
OPR3|OPR6|OPR7|OPR8|OPR9|OPRCMFE|MSW1|MSW2

------------------------------------------------------------
SAP允許用戶修改的消息都save在T100S中,你配置后的消息從T100C可看到
但是如果我將不允許的消息強行coding塞進去,會有什么后果呢?
-------------------------------------------------------------

***嚴格地將下面的T-code多是設置output打印的.
