If you use Aurena, you need to use the Aurena URL. Also note that you have two element and lobby types; Enterprise Explorer or Aurena. The following documentation should be useful.

Bonus tip; if you want the filter to be language independent. It's better to use OBJSTATE. As State is a translated value. 

Thank you for that, Could you clarify about the OBJSTATE? 
I was looking to filter by the Status and then count how many PO’s were closed. the Status column appears to be “STATE” though so that is what i used? 

OBJSTATE is the actual database value which always remains the same.

STATE is a translated value which depends on the language of the user.

e.g. OBJSTATE = ‘Closed’ 

STATE when logged in in English is ‘Closed’ 

STATE when logged in in Dutch is ‘Gesloten’ 

STATE when logged in in German is ‘Geschlossen’ 

If you only use 1 language in IFS it does not make a difference .

We potentially will be using multiple languages so this is important to understand when creating custom lobbies. Does this apply to other Fields / Database values? 
 

for the other column in this example “ORDER_NO”, Would this be OBJORDER_NO? most importantly - How do i select these ? - The only option i can see is the English spellings of the columns? 

Thanks again for your help!

State is one of the few fields which get translated in runtime. Normal data fields do not, as you are typing them in manually.
