Consuming a Bapi Web Service from a .Net application

[Former Member]

Hello World,

I need to call a BAPI from a .Net application. Any standard built-in BAPI would be fine. Just need to prove it's workable in the project environment by passing some values and getting the response. A DIRECT call w/o XI involved.

Any code snippets or links would be appreciated.

P.S. I did try to access the link below to get some WSDLs that i got from a pdf doc called "SAP RFC via Web Services", but the page just couldn't get displayed.

Regards,

Steve

Hi Steve,

How are you doing ?

the links above are a gr8 guide.

here is some code for writing a web service invoking an RFC [Bapi_Vendor_Getdetail] in C#

the connection related class method are specified in a related thread

with respect,

amit

[WebMethod]

public DataSet GetVendorDetails(string strCompanyCode, string strVendorNo, string strConnection)

{

DataSet dsxVendor;

dsxVendor = null;

//connection string : "CLIENT=100 USER=chawathe PASSWD=amit LANG=en ASHOST=chawathe.realtech.co.nz SYSNR=0"

SAPConnect myConnector = new SAPConnect();

if(strVendorNo.Trim() !="")

{

SAP.Connector.Connection con2SAP;

con2SAP = myConnector.conEstablishConnection(strConnection);

if (con2SAP != null)

{

prxVendor prxVendorDetails = new prxVendor();

BAPIRET1 brtVendor = new BAPIRET1();

BAPIVENDOR_06Table zptBank = new BAPIVENDOR_06Table();

BAPIVENDOR_04 zpsVendor = new BAPIVENDOR_04();

BAPIVENDOR_05 zpsCompany = new BAPIVENDOR_05();

DataFormatConverter myDFC = new DataFormatConverter();

string strRFCReturnStatus;

try

{

con2SAP.Open();

prxVendorDetails.Connection = con2SAP;

prxVendorDetails.Bapi_Vendor_Getdetail(strCompanyCode,strVendorNo,out zpsCompany, out zpsVendor, out brtVendor, ref zptBank);

// check if details were retrieved

strRFCReturnStatus = brtVendor.Type.Trim();

switch(strRFCReturnStatus)

{

case "E":

case "A":

case "W":

// do not proceed with extraction of the result

// error, abort, warning

break;

case "S":

case "I":

default:

// proceed with extraction of the result

// output dataset creator

DataSetStructureCreator myDSSC = new DataSetStructureCreator();

dsxVendor = myDSSC.dsxCreateStructure(iConst.DS_VEN_OUT);

DataRow drxDetails;

drxDetails = null;

drxDetails = dsxVendor.Tables[iConst.DT_VEN_DET].NewRow();

drxDetails[iConst.DC_VG_LIFNR] = zpsVendor.Vendor.ToString().Trim();

drxDetails[iConst.DC_VG_NAME1] = zpsVendor.Name.ToString().Trim();

dsxVendor.Tables[iConst.DT_VEN_DET].Rows.Add(drxDetails);

drxDetails = null;

drxDetails = dsxVendor.Tables[iConst.DT_VCO_DET].NewRow();

drxDetails[iConst.DC_VC_LIFNR]= zpsCompany.Vendor.ToString().Trim();

drxDetails[iConst.DC_VC_BUKRS]= zpsCompany.Comp_Code.ToString().Trim();

dsxVendor.Tables[iConst.DT_VCO_DET].Rows.Add(drxDetails);

break;

}

}

catch (Exception ex)

{

string strError;

strError = ex.Message.Trim();

dsxVendor = null;

}

finally

{

if (con2SAP.IsOpen)

{

// close connection

con2SAP.Close();

}

// return to pool

myConnector.conReturnConnection(con2SAP);

}

}

}

return dsxVendor;

}

Hi

Hope tis code will help you out.

After creating a SAPProxy drag the Bapi "RFC_CUSTOMER_GET " onto it.Now on the aspx page drag a button,datagrid.

Set the datasource proerty of the datagrid to the respective table of the bapi.

Then write the following code:

To call RFC_CUSTOMER_GET and return results, write code in the Button1_Click event handler, as shown below.

private void Button1_Click(object sender, System.EventArgs e)

{

sapProxy11.Rfc_Customer_Get();

this.DataBind();

}
