SAP EH&S RFC Connection error in SM59


Hi Experts,

I am facing issues in RFC Connection error in SM59.

I am working on Report Management in Product Safety for which I have set up WWI server and established RFC connections for the same.

  • 1)Initially, when I test in SM59 the connection was positive for the below RFC connections.

WWI_GENPC1 (Initially was positive but after creating a report the test was negative)




  • 2)Please find the screen shots below from CGSADM

RFC Connection WWI_GENPC1 failed to connect to Generation Server SV001 – Initially was working

But, RFC Connections WWI_GENPC2, WWI_GENPC3 and WWI_GENSRV_1 are working as expected

  • 3)Screen shot from Specify Generation Servers

Here, Generation Server SV001 is connection to WWI Server via RFC WWI_GENPC1 and is active.

  • 4)Screen shot from CG5Z

But, the backgroung job for program RC1WWIDP i.e.. Dispatcher Job is taking long time to complete i.e.. just because RFC connection is getting failed WWI_GENPC1 for SV001. Initially, WWI_GENPC1 was working fine but when a report is created the test is getting failed in SM59.

I have checked with BASIS Team for quite a couple of times for which they will open the connection and initially it works fine but when I create another report again I face the same issue as there is no consistency in RFC connections.

Please help me out to fix the problem permanently.

Thanks in advance

    Hi Darshan,

    There is no easy answer we can give you without access to the system...
    Make sure you have read and understand the WWI Cookbock in SAP note 1394553 - it explains everything about the WWI Setup.

    If that doesn't help please check:

    Hi Darshan,

    There are number of issues with the set up. They include

    - WWI services are not set up properly or are not running in the WWI server (Checks services in the windows server)

    - The background jobs for the WWI instances like SV001 are not set up properly (Check jobs for WWI dispatcher and schedule them accordingly)

    - The windows authorization for the WWI admin user is not sufficient to run the service (Check user role and modify it accordingly)

    - Finally the Configuration of Generation servers configuration activity contains entries which are not relevant, but just maintained because of carry forward configuration (Delete non relevant configuration entries and create a fresh entries) .

    Fix these issues, it will work properly

    Thanks and Regards

      • Hi Jayakumar,
      • Thanks for your quick reply.
      • As mentioned by you in point 1 I had stopped the service in CGSADM and restarted again and the RFC connection WWI_GENPC1 is working fine.
      • Now, I have set up the WWI jobs according to note 1094307 but the dispatcher job WWI DISPATCH PROCESS for ABAP program RC1WWIDP is taking too long to complete as a result reports are in Generation possible status in CG50.
      • I have checked configurations and it looks fine.
      • Thanks in advance
