allow three part names in db2 for i services

please add ability to use three-part naming in UDTF or in db2 for i services like
QSYS2.JOB_INFO
It seems that the 3-part naming isn't working or supported in UDTFs. .e.g.:
https://www.ibm.com/developerworks/community/wikis/home?lang=en#!/wiki/IBM%20i%20Technology%20Updates/page/QSYS2.JOB_INFO%20UDTF

SELECT * FROM TABLE(QSYS2.JOB_INFO(JOB_USER_FILTER => 'SCOTTF', JOB_STATUS_FILTER => '*JOBQ')) X;


Use Case:

someone could simply use a central IBM i system to retrieve information from various systems.
like how long did my backup take one system a, system b, system c .. or day-end processing statistics.

    IBM does not intend to provide a solution to this request at this time, so it is being closed. This request has a low priority since there is a work-around.

    To direct a table function to be run on a remote system, add a three-part reference to a table on that system. Here is an example. Replace RMTDB with the system you want to access.

    select current server, h.*
    from table(qsys2.history_log_info()) h
    where exists
    (select 1 from RMTDB.sysibm.sysdummy1);

    Hi,
    We haven't yet considered whether or not to provide this enhancement.
    I should point out that there are two alternatives that could be used today:
    1) Create a procedure on the target IBM i's that invokes the UDTF. Call the procedure using 3-part names.
    2) Create a view on the target IBM i's where the view invokes the UDTF. Query the view using 3-part names.
    2b) The view could be parameterized using global variables.
    Regards, Scott

    The CAAC has reviewed this requirement and recommends that IBM view this as a “nice to have” low priority feature to the general IBM i community. There are alternate ways to do this, though they are a bit involved. The audience for this would be those with multiple systems running the same application stack, and it would be much appreciated by them.

    Background: The COMMON Americas Advisory Council (CAAC) members have a broad range of experience in working with small and medium-sized IBM i customers. CAAC has a key role in working with IBM i development to help assess the value and impact of individual RFEs on the broader IBM i community, and has therefore reviewed your RFE.

Allow three part naming on table functions

I'd like to see the ability to use three part naming on table functions, like RemoteSystem.QSYS2.HISTORY_LOG_INFO Use Case: Retrieving statistics for a system health dashboard.
