自定义BAPI的基本资料

BAPI的简单实现步骤

一，创建Function Module

1，在SM11，创建需要的structure

2，在SE80，建Function group

3，在SE37，创建Function Module

 

Note：一个Function Group只能包含一个BAPI；参数传值；必须有有一个BAPIRETURN类型的EXPORT参数

 

二，封装

1，在SWO1，建Object Type

2，把Function Module作为一个Method加入，utilities->API Methods->Add Method

3，release Object和Module。使在BAPI Browser 中可以看到。也就是外部能够调用。

 

三，调用

1，如在另一系统中用ABAP调用，先在SM59中建RFC联到有BAPI的R/3，(ZGOGO)

在SE38的程序中调用，Call Function "ZBAPIXXXXX" DESTINATION ZGOGO EXPORTING ...

 

2，如用JAVA调用

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.*;

 

建立连接；调用。。。（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

VBA2

Private 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.Connection

sapConnection.Client = "800"
sapConnection.user = "user"
sapConnection.Language = "EN"

If sapConnection.logon(0, False) <> True Then
MsgBox "No connection to R/3!"

End If

Set 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
