parallel processing maximum sessions error

Former Member — Wed, 24 Feb 2016 08:40:52 GMT

Hi Experts,

I have implemented a parallel processing logic inside a report. I created a FM and calling in using STARTING A NEW TASK IN GROUP addition. Inside this FM there is a RFC call to other system. when I am executing this report, I am getting pop-up s saying 'Maximum number of GUI sessions reached". Why is this pop-up coming. Is the number of parallel sessions are limited to number of maximum sessions that a user can open? I am not using any CALL SCREEN or CALL TRANSACTION inside the code.

thanks,

sankar.

You could use


call function 'TH_USER_INFO'
  importing
  act_sessions = act_sessions
  max_sessions = max_sessions.

to prevent this error, read also 734205 - Remote GUI check in module TH_USER_INFO .

(Also check with RZ11 value of rdisp/max_alt_modes)

Regards,

Raymond

Hi Raymond,

RZ11 parameter has value 6. When I run the parallel process report, in SM50 I see there are 20 dialog WPs that are keep running. Then after some time I get this pop-up saying maximum SAP-GUI sessions reached. So what exactly is happening? Does the RFC call opens another session internally? If I understand the significance of RZ11 parameter,we can attach 6 user sessions to a single dialog WP. Am i right?

thanks,

sankar

Have you called the Function module inside a loop?
