Hi

We are developing Mobile Application in 1C:Enterprise 8.3 that is working normally.

For Mobile Applications does not exist command Query. In Catalogs I need to get that Items that have the True value in attribute. For that we have to use onely Select command.

Question: Can we use command like Catalogs.Items.Select(,,New Structure("AttributeBoolean", True)); ?????

I got the error "Invalid parameter value (parameter number '3')".

Or available another alternative solution that I don't know?? Any ideas?

&AtClient
Procedure Command(Command)
   ServerCall();   
EndProcedure

&AtServer
Procedure ServerCall()
   
   Selection = Catalogs.Items.Select(,,New Structure("AttributeBoolean", True));
   While Selection.Next()  Do
      ItWorks = Selection.AttributeBoolean;
      Break;
   EndDo;
   
EndProcedure 

You need check that for the catalog attribute AttributeBoolean indexing is set in Designer mode to "Index" or "Index with additional ordering" value.

you can read more about conditions which are imposed on the <Filter> at Syntax assistant

thanks solved it.
