Bapi Error when connecting through .net connector

Former Member

Could anyone help me with this error and the reason for this error. We have two SAP Systems, one for development and other one for test.

When I run my .net program to execute the same BAPI on SAP development system, my program runs fine and no errors/exceptions occur.

But when I run the program to connect to SAP Test system, I get the following error. The exception occurs as soon as I call the bapi. This is a custom bapi that we are trying to call. Is there any way we can test whether the connection to SAP system is established before calling the BAPI ?

It seems that you were calling a customer BAPI which is

defined in your dev system but not defined in your test system.

To verify if the connection can be established, you can explicitly make a call to Connection.Open() before calling the BAPI method. But it is usually not necessary because the exception thrown by the method call will tell if it is a connection error or not. An RfcCommunicationException or RfcLogonException indicates a error when establishing the connection.
