JCO.Server could not find server function - Intermittent error

Dear Gurus,

I have created an RFC function module that will be called in SAP PO system (SAP PI 7.50). using SLD_NUC Program ID.

I've done all the necessary connection, and the RFC call triggered well most of the times. I got the desired result, and everything works perfectly.

but every now and then, when we tried to trigger this RFC from our program or explicit call via SE37, this RFC will return the System Error, - JCO.Server could not find server function -Function_Name-.

Is there any idea to which why this might happens? We're still in the development phase, but I am not sure if this solution could work if we can't ensure it's reliability.

any suggestion is welcomed.

Thanks!

    Hi Raymond,

    Program SLD_UC and SLD_NUC are standard programs, which are created automatically and used to push system data from ABAP system to Java only SLD, for example, if any other ABAP backend system connects to your PO system and push data to PO SLD, then these program will be used.

    So you should not use these program IDs for other purpose. For more details, please check the following blog:

    https://blogs.sap.com/2011/02/23/how-to-push-abap-system-data-to-a-java-only-sld/

    Please change the program ID to another one, also avoid to use any standard program IDs e.g AI_RUNTIME_<SID> , XI_IDOC_DEFAULT_<SID>.

    Best Regards,

    Liz
