Issue in Multiple JCO Destinations

Hai All,

I have a DynPro Application which uses Bapi model from one JCO Destination ; is there any way to have another JCO Destination to create another model for another BAPI?

Thanks in Advance,

Phani Ach

    Hi,

    In a WebDynpro Application, each model has a set of JCos (one RFC metadata connetion and one modeldata).

    Everytime you import a model with a new BAPI/RFC then you would be giving a set of JCos. Ofcourse you can have only one set everyrime for all the models.

    Inorder to improve the performance, it is better to have only one model with all the Bapis connected to it. You can re-import the model to add more BAPIs to it. The problem here is that your JCos get locked frequently - to avoid this increase the JCos Max Pool size from default settings to say 100, this can be done in Wed Dynpro Console under Content Administration. (Requires Cache invalidation on J2EE engine or J2EE engine restart)

    Hope this helps.

    Thanks,

    Vamshi

    Hi Phani Raghavendra Achanta,

    You can use another model by using different JCO Destination. But ! if you just want to use another BAPI, you can obviously add another BAPI to the existing model ( but ! sam JCO ).

    You can select among the whatever the option you want.

    points if useful

    Thanks

    Phani,

    To connect different BAPIs from various R/3 system. Create seperate model to connect seperate systems. You can have many BAPI in a single model but the same system. Because When you create a model you need to define 2 destinations one for RFC model data and another for META data. Later You will create the JCO destinatoins for only system. So I suggest you to use different models to connect different system.
