周圍的人都比較忙，一切得靠自己學，慢慢摸索。

BAPI有的是類，有的是函數。'Business?application?programming?interface'的簡稱。?

BAPI?is?'Business?application?programming?interface',?similar?to?API.?which?are?stable,?standardized?methods?to?access?data?in?R/3?

To?use?BAPIs?to?access?SAP?business?objects?you?will?need?a?good?understanding?of?object-oriented?programming.?You?should?also?have?a?basic?knowledge?of?the?R/3?System.?

BAPIs?can?be?accessed?from?various?programming?environments,?for?example,?Delphi/Connect?from?Inprise?(formerly?Borland),?Microsoft’s?Visual?Studio,?C++?and?Java?platforms.?You?must?be?familiar?with?the?development?environment?used?to?access?BAPIs.?

BAPIs?are?available?from?development?platforms?external?to?R/3?that?support?the?Remote?Function?Call?(RFC)?protocol.?If?you?are?developing?your?application?in?a?non-object?oriented?programming?language,?you?need?to?have?RFC?programming?skills?to?call?BAPIs?via?RFC.?In?particular,?you?need?to?know?how?to?perform?RFC?calls.

BAPI的簡單實現步驟
一，創建Function?Module?

1，在SM11，創建需要的structure?

2，在SE80，建Function?group?

3，在SE37，創建Function?Module?


Note：一個Function?Group只能包含一個BAPI；參數傳值；必須有有一個BAPIRETURN類型的EXPORT參數?


二，封裝?

1，在SWO1，建Object?Type?

2，把Function?Module作為一個Method加入，utilities->API?Methods->Add?Method?

3，release?Object和Module。使在BAPI?Browser?中可以看到。也就是外部能夠調用。?


三，調用?

1，如在另一系統中用ABAP調用，先在SM59中建RFC聯到有BAPI的R/3，(ZGOGO)?

在SE38的程序中調用，Call?Function?"ZBAPIXXXXX"?DESTINATION?ZGOGO?EXPORTING?...?


2，如用JAVA調用?

引入包；（不一定要用IBM的）?

import?com.sap.rfc.*;?

import?com.sap.rfc.exception.*;?

import?com.ibm.sap.bapi.*;?

import?com.ibm.sap.bapi.generated.*;?


建立連接；調用。。。（See?CALL_BAPI.java）?

VBA?for?SAP?

Private?Sub?CommandButton1_Click()
Set?oFunction?=?CreateObject("SAP.LogonControl.1")
Set?oConnection?=?oFunction.NewConnection
oConnection.Client?=?"500"
oConnection.Language?=?"EN"
oConnection.User?=?"user"
oConnection.Password?=?"pasword"
oConnection.ApplicationServer?=?"sap1.yok.com.cn"
oConnection.SystemNumber?=?"01"
result?=?oConnection.Logon(0,?True)
Set?ofun?=?CreateObject("SAP.FUNCTIONS")
Set?ofun.Connection?=?oConnection
Set?func?=?ofun.Add("RFC_READ_TABLE")
func.Exports("QUERY_TABLE")?=?"MARA"
If?func.Call?=?True?Then
Set?oline?=?func.tables.Item("DATA")
Row?=?oline.rowcount
i?=?1
Do?While?i?<=?Row
???Cells(i,?1)?=?Mid(Trim(oline.Value(i,?1)),?4,?22)
?????i?=?i?+?1
???Loop
???Else
???MsgBox?"FAIL"
End?If
End?Sub

VBA2Private?Sub?CommandButton1_Click()
Dim?sapFunctionCtrl?As?Object?????????'Function?Control?(Collective?object)
Dim?sapConnection?As?Object???????????'Connection?object
Dim?theFunc?As?Object?????????????????'Function?object
????
Set?sapFunctionCtrl?=?CreateObject("SAP.Functions")
Set?sapConnection?=?sapFunctionCtrl.ConnectionsapConnection.Client?=?"800"
sapConnection.user?=?"user"
sapConnection.Language?=?"EN"If?sapConnection.logon(0,?False)?<>?True?Then
MsgBox?"No?connection?to?R/3!"End?IfSet?theFunc?=?sapFunctionCtrl.Add("ZRFCPING")
If?theFunc.call?Then?'?call?the?RFC?FM
MsgBox?"RFC?call?is?okay"
End?If
sapFunctionCtrl.Connection.logoff
Set?sapConnection?=?Nothing
Set?sapFunctionCtrl?=?Nothing
End?Sub

其他還有很多，有幾個demo~?
