How to get navigation state
I would like to get the navigation state of a query to call the 'Web Service for Accessing Query Data'.
In the documentation at http://help.sap.com/saphelp_nw04/helpdata/en/d8/3bfc3f8fc2c542e10000000a1550b0/frameset.htm
there is a parameter called 'Parameter' that allows you to set Data Provider Commands, i.e. the navigation status. But how do I get it? Within a BeX Web Application, when someone fixes a certain column or does something similar - how do I get this information? For each web item I can access it's attributes but how do I get the navigation status to send it to the 'Query'-web service?
