I have a C# console application that connects to a SAP server to get data from some of its tables.
Sometimes this error pops up when I try to copy a value from a field in a SAP table called SOHEADER to a string variable.
Here's the stack trace:
SAP.Middleware.Connector.RfcInvalidParameterException: Table line 0 out of range: table is empty en SAP.Middleware.Connector.RfcTable.get_Item(Int32 lineIndex) en ExportarPedidosSAP.Program.ControlFacturasRemitosNotasCreditos(RfcDestination rfcDest, String& nroerror) en C:\Users\USER\Source\repos\BSCPY\BSCPY\ExportarPedidosSAP\Program.cs:línea 1220 en ExportarPedidosSAP.Program.ConnSAPNotasCreditos() en C:\Users\USER\Source\repos\BSCPY\BSCPY\ExportarPedidosSAP\Program.cs:línea 936
Here is the ControlFacturasRemitosNotasCreditos function:
static void ControlFacturasRemitosNotasCreditos(RfcDestination rfcDest, out string nroerror)
{
Console.WriteLine("** Controlando remitos... ");
nroerror = "";

Line 1220 inside ControlFacturasRemitosNotasCreditos:
status_doc = Convert.ToString(tableHstatus[0].GetValue("GBSTK")).ToUpper();
Line 936 inside ConnSAPNotasCreditos that calls the ControlFacturasRemitosNotasCreditos function:
ControlFacturasRemitosNotasCreditos(rfcDest, out nroerror);
Can somebodoy tell me what could be the issue here? Could it be that the field comes empty from the SAP table and if i try to copy it somewhere the whole thing crashes? Is there a safe way to check if the field is null before trying to copy it?
