Execute BAPIs/Function Modules

This section contains a list of available resources for the BAPI/Function Module classes.

Call BAPIs/Function Modules

Follow the steps below to call BAPIs/Function Modules:

1. Connect to the SAP system using R3Connection.
2. Create an RFCFunction object using CreateFunction.
3. Provide values to export parameters, table parameters or import parameters for the RFCFunction objects.
   • Export parameters:
     Exports["parameter_name"].ParamValue or
     Exports["structure_name"].ToStructure()["parameter:name"].
   • Table parameters: Tables["table_name"]["parameter_name"].ParamValue
   • Import parameters:
     Imports["parameter_name"].ParamValue or
     Imports["structure_name"].ToStructure()["parameter:name"].
4. Execute the BAPIs/function modules using Execute.

The following sample code calls the BAPI BAPI_REQUISITION_GETDETAIL to get the processing status of a purchase requisition:

public static void BanfStatus(string Banf_Number)
{
    RFCFunction func = connection.CreateFunction("BAPI_REQUISITION_GETDETAIL");
    func.Exports["NUMBER"].ParamValue = Banf_Number; 

    func.Execute();

    if (func.Tables["Return"].RowCount > 0)
    {
     string rMessage = func.Tables["Return"].Rows[0, "MESSAGE"].ToString();
     Console.WriteLine(rMessage);
    }
    if (func.Tables["REQUISITION_ITEMS"].RowCount > 0)
    {

     foreach (RFCStructure dr in func.Tables["REQUISITION_ITEMS"].Rows)
     {
       Console.WriteLine("BelgNummer:" + dr["PREQ_NO"].ToString() + " Pos: " + 
       dr["PREQ_ITEM"].ToString() + " Status: " + dr["PROC_STAT"].ToString());
     }
}
