Ccap_Alt_Date_Create not working in ASP.NET C#

[Former Member]

Hello all,

I have tested with Ccap_Alt_Date_Create to create change number alternative date but failed. I have tried both SAP dot net connector 1.0 and 2.0 in Visual Studio 2003, but both failed.

It worked well in ABAP program.

I have tested with these code in a webform:

################

SAPProxy1 proxy1;

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

{

string strSapConn = "ashost=asmera sysnr=00 client=18 user=xxx passwd=xxx";

proxy1 = new SAPProxy1(strSapConn);

proxy1.Connection.Open();

AsyncCallback callback = new AsyncCallback(this.Ccap_Alt_Date_CreateAsyncCallback);

proxy1.BeginCcap_Alt_Date_Create("CHGNO1-03", "CHGNO1", "20041226", callback, null);

proxy1.Ccap_Alt_Date_Create("CHGNO1-03", "CHGNO1", "20041226");

}

protected void Ccap_Alt_Date_CreateAsyncCallback(IAsyncResult asycnResult)

{

proxy1.EndCcap_Alt_Date_Create(asycnResult);

proxy1.CommitWork();

proxy1.Connection.Close();

}

################

It threw the following exception:

Please give advice if anyone has successfully used it.

Thank you very much!

Hi,

Why did you make an asynchronous call and a synchronous call one after the other? Please remove the asynchronous call and see whether you still get the same error.

Hi cb lee

Also, you can also ask your ABAP team to examine the RFM for the ERROR object which is defined as an exception in the function module .

On an initial look it seems that the exception is being raised in the code section marked as "General Preparation for all API-FB" in the FM code. Please refer to include LCCAPFA2

Thx, Gaurav

Hi

SAP.Connector.RfcAbapException is a managed .net type which is raised when an exception is thrown by the ABAP program.

I would advise you to check your RFM -"Ccap_Alt_Date_Create" for the scenarios in which it would raise the custom exception. Then try again by changing the parameters to the Ccap_Alt_Date_Create.

Cheers
