SAP Web GUI Time Out error when using Citrix

ashok_oleti — Thu, 25 Jun 2015 05:04:54 GMT

Hi,

Our users are facing error "400 Session timed out - please login again" (Screenshot Attaced) when they open the web gui link via CITRIX. The Web GUI session opens up with out any error but it gives Time out immediately after clicking on any tab of the web page. But there is no such problem when the link is opened in WAN network.

System Environment is

Product : ECC 6.0 on EHP4

Basis : SAP_BASIS 701 SP14

Kernel : 720 SP 500

OS : Windows Server 2008 R2

DB : MS SQL Server 2008 R2

I have checked the trace files of ICM and ICF and I have found below logs

Log from dev_icf2 file:

Hello Ashok,

This is not an ITS issue per se - rather ICM or Web Dispatcher if you use one.

See the following note

2142478 - Lost or no responses when using the SAP Web
Dispatcher for SAP ME

Take note of the ICM parameters that they recommend increasing.

Regards,

Oisin

Hi Oisin,

Thanks for looking into this post.

No, we are not using any web dispatcher in this case and also the web gui is working fine when opened in WAN.

Hello Ashok,

Have you tried setting the parameter

icm/traffic_control NETTIMEOUT=600

as per note ref in my last reply?

I didnt find these transactions in my system.

Anyhow the issue is fixed now. We had to add all the web gui links to Compatibility view settings of Internet Explorer in Citrix.
