java 调用bapi_BAPI的简单实现步骤

大家好，又见面了，我是你们的朋友全栈君。

一，创建Function Module

1，在SE11，创建需要的structure (必须为flat类型,否则会出现Reference parameters are not allowed with RFC)

2，在SE80，建Function group

3，在SE37，创建Function Module(import的参数入药是value传值)

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
