BAPI的結構，BAPI裡的代碼可以分為這樣兩部分：
1、一部分是資料校核，檢查傳入的資料是否滿足建立相關業務對象的條件，并且把錯誤消息回報出來；
2、另一部分是更新資料庫，即UPDATE/INSERT/DELETE dbtab這樣的操作。
1 BAPI的優點
bapi是面向對象的設計;
bapi是固定的,一般不能修改;
bapi可以被sap内部部件和非sap程式使用;
bapi的成功和錯誤資訊始終通過RETURN傳回;
bapi可以被許多開發平台使用;
2 何時該考慮使用BAPI設計程式
用VB/JAVA?C++等語言編寫非SAPGUI程式通路和處理sap資料;
SAP不同部件之間通訊;
與非sap程式或者老系統交換資料:
使用異步通信分發資料如:ALE
可以通過SAP Business Connector or Internet Application Components 與網際網路程式內建;
3 關于RETURN
RETURN用于BAPI傳回錯誤和成功的消息,它可以是BAPIRETURN,BAPIRETURN,BAPIRET1,BAPIRET2和BAPIRET2_FIX中的一種類型.這些結構一般都包括以下字段:
SORT return BY type number row.
LOOP AT return WHERE type = ‘E’ OR type = ‘A’.
ENDLOOP.
如果sy-subrc = 0，CALL FUNCTION ‘BAPI_TRANSACTION_ROLLBACK’.
否則
CALL FUNCTION ‘BAPI_TRANSACTION_COMMIT’
EXPORTING
wait = ‘X’ “參數wait指派‘X’,送出完之後才回進行後面的代碼
IMPORTING
return = ls_commit_return.
| TYPE | CHAR 1 | S= success message E = error message W = warning message I = information message A = termination message (abort)終止消息(中止) |
|---|---|---|
| ID | CHAR 20 | Message ID The structure BAPIRET2 takes into account the name space extension for the message class as of Release 4.0. If you want messages to be compatible with earlier R/3 Releases, use the message classes before Release 4.0. |
| NUMBER | NUMC 3 | Message number |
| MESSAGE | CHAR 220 | Full message text from the message table. All variables (in fields Message_V1 to Message_V4) have been replaced with text. |
| MESSAGE_V1 MESSAGE_V2 MESSAGE_V3 MESSAGE_V4 | CHAR 50 | Fields for the variable texts of the message |
