RFC Destination questions

Hello Everybody! Some simple questions about RFC, please help me:

1) Should I have configured <b>only one</b> RFC Destination (type TCP/IP) from ECC to XI, that all ABAP programms would use on a CALL FUNCTION statement?

2) Could I have configured only one RFC Sender Channel as well as only one RFC Receiver Channel for all the interfaces? If that is the case, what about the parameter "Initial Connections" ? If it's value is "1", I can't do two RFC calls at the same time, can I?

Thanks

Julio

    One RFC destination is enough

    One Sender and Receiver Channel is enough. Keep in mind that you need to create a sender agreement for each interface.

    With "Initial Connections" value 1, you can also make two RFC calls at the same time. The maximum RFC calls is restricted by "Maximum Connections"

    Yes. One should be sufficient.

    Yes, the same Sender and Receiver RFC adapters can be used for multiple calls and for different interfaces.

    The RFC adapters ( both sender and receiver) contain the details for pulling the RFC metadata and so you can use one Sender and Receiver RFC adapter for multiple calls and multiple RFC's.

    Hey Julio,

    1) Should I have configured only one RFC Destination (type TCP/IP) from ECC to XI, that all ABAP programms would use on a CALL FUNCTION statement?

    Are you calling a function which is base on XI ABAP Stack?

    If you are calling Function Module on R/3 side from XI -ABAP then you need to configure RFC destination on XI to ECC.

    Hi,

    For your first question --> If you are sending data from ECC to XI only one RFC Destination (TCP/IP) type is needed from ECC to XI at ECC System.

    If you are sending data from XI to ECC, one other RFC Destination is needed from XI to ECC at XI System.

    For your second question --> There is no need to create communication channel when RFC or IDOC is sender.

    For RFC receiver, you have to create one RFC Receiver Communication channel, if you are posting data from XI to ECC.
