Is it possible to keep a rfc session opened in sap with JCO?

Hi guys,

I was wondering if it was posible to keep an rfc called via JCO opened in SAP memory so i can cache stuff, this is the scenario i have in mind:

Suppose a simple function that increments a number. The function starts with 0, so the first time i call it with import parameter 1 it should return 1.

The second time i call it it should return 2 and so on.

Is this posible with JCO?

If i have the function object and make two succesive calls it always return 1.

Can i do what i'm picturing?

    Hi Fernando,

    you are talking of stateful call sequences. Yes, this is possible.

    Please have a look into the JCo JavaDoc for class

    Best regards,
