But if i try to extract a table qlik sense returns the following error:

Hi again Michele,

There are a few things to check with firewall and 'SAP services file'. Have a look in this document:

Hi Hakan,

i've checked the document but we have no firewalls on both side (qlik - SAP).

I'm connectiong to an "Application Server" so a change into "SAP service file" (C:\WINDOWS\system32\drivers\etc\services) is not needed in this case.

Anyway i have tried to add a new row (sapmsTST 3600/tcs) on that file but nothing has changed.

The error was on the "Host" name.

By writhing only machine name "ssvsa112" without the domain it works!
